Passage Of California Stem Cell Proposition Boosts Research

For the last decade and more, Stem Cell research and regenerative medicine have been the rave of the healthcare industry, a delicate area that has seen steady advancements over the last few years.

The promise of regenerative medicine is simple but profound that one day medical experts will be able to diagnose a problem, remove some of our body cells called stem cells and use them to grow a cure for our ailment. Using our body cells will create a highly personalized therapy attuned to our genes and systems.

The terminologies often used in this field of medicine can get a bit fuzzy for the uninitiated, so in this article, I have relied heavily on the insights of Christian Drapeau, a neurophysiologist and stem cell expert.

Drapeau was one of the first voices who discovered and began to speak about stem cells being the bodys repair system in the early 2000s. Since then, he has gone on to discover the first stem cell mobilizer, and his studies and research delivered the proof of concept that the AFA (Aphanizomenon flos-aquae) extract was capable of enhancing repair from muscle injury.

Christian Drapeau is also the founder of Kalyagen, astem cell research-based company, and the manufacturers of Stemregen. This stem cell mobilizer combines some of the most effective stem cell mobilizers Drapeau has discovered to create an effective treatment for varying diseases.

How exactly do stem cell-based treatments work? And how is it delivering on its promise of boosting our abilities to regenerate or self-heal?

Drapeau explains the concept for us;

Stem cells are mother cells or blank cells produced by the bone marrow. As they are released from the bone marrow stem cells can travel to any organ and tissue of the body, where they can transform into cells of that tissue.Stem cells constitute the repair system of the body.

The discovery of this function has led scientists on a long journey to discover how to use stem cells to cure diseases, which are essentially caused by cellular loss. Diseases like Diabetes and age-related degenerative diseases are all associated with the loss of a type of cell or cellular function.

However, what Drapeaus research has unearthed over the last few decades is that there are naturally occurring substances that show a demonstrated ability to induce the release of stem cells from the bone marrow. These stem cells then enter the bloodstream, from where they can travel to sites of cell deficiency or injury in the body to aid healing and regeneration. This process is referred to as Endogenous Stem Cell Mobilization (ESCM).

Stemregen is our most potent creation so far, explains Drapeau, and it has shown excellent results with the treatment of problems in the endocrine system, muscles, kidneys, respiratory systems, and even with issues of erectile dysfunction.

Despite the stunning advancements that have been made so far, a concern that both Drapeau and I share is how this innovation can be merged with another exciting innovation; AI.

Is it even a possibility? Drapeau, an AI enthusiast, explains that AI has already been a life-saver in stem cell research and has even more potential.

On closer observation, there are a few areas in which AI has greatly benefited stem cell research and regenerative medicine.

One obstacle that scientists have consistently faced with delivering the full promise of regenerative medicine is the complexity of the available data.Cells are so different from each other that scientists can struggle with predicting what the cells will do in any given therapeutic scenario. Scientists are faced with millions of ways that medical therapy could go wrong.

Most AI experts believe that in almost any field, AI can provide a solution whenever there is a problem with data analysis and predictive analysis.

Carl Simon, a biologist at the National Institute of Standards and Technology (NIST) and Nicholas Schaub recentlytested this hypothesiswhen they applied Deep Neural Networks (DNN), an AI program to the data they had collected in their experiments on eye cells. Their research revolved around causes and solutions for age-related eye degeneration. The results were stunning; the AI made only one incorrect prediction about cell changes out of 36 predictions it was asked to make.

Their program learned how to predict cell function in different scenarios and settings from annotated images of cells. It soon could rapidly analyze images of the lab-grown eye tissues to classify the tissues as good or bad. This discovery has raised optimism in the stem cell research space.

Drapeau explains why this is so exciting;

When we talk about stem cells in general, we say stem cells as if they were all one thing, but there are many different types of stem cells.For example, hair follicle and dental pulp stem cells contain neuronal markers and can easily transform into neurons to repair the brain. Furthermore, the tissue undergoing repair must signal to attract stem cells and must secrete compounds to stimulate stem cell function. A complex analysis of the tissue that needs repair and the conditions of that tissue using AI, in any specific individual, will help select the right type of stem cells and the best cells in that stem cell population, along with the accompanying treatment to optimize stem cell-based tissue repair.

Christian Drapeau

Ina study published in Februaryof this year inStem Cells, researchers from Tokyo Medical and Dental University (TMDU) reported that their AI system, called DeepACT, had successfully identified healthy, productive skin stem cells with the same accuracy that a human could. This discovery further strengthens Drapeaus argument on the potentials of AI in this field.

This experiment owes its success to AIs machine learning capabilities, but it is expected that Deep Learning can be beneficially introduced into regenerative medicine.There are many futuristic projections for these possibilities, but many of them are not as far-fetched as they may first seem.

Researchers believe that AI can help fast-track the translation of regenerative medicine into clinical practice; the technology can be used to predict cell behavior in different environments. Therefore, hypothetically, it can be used to simulate the human environment. This means that researchers can gain in-depth information more rapidly.

Perhaps the most daring expectation is the possibility of using AI to pioneer the 3D printing of organs. In a world where organ shortage is a harsh reality, this would certainly come in handy. AI algorithms can be utilized to identify the best materials for artificial organs, understand the anatomic challenges during treatment, and design the organ.

Can stem cells actually be used along with other biological materials to grow functional 3D-printed organs? If this is possible, then pacemakers will soon give way to 3D-printed hearts. A 3D-printedheart valvehas already become a reality in India, making this even more of an imminent possibility.

While all of these possibilities excite Drapeau, he is confident that AIs capabilities with data analysis and prediction, which is already largely in use, would go down as its most beneficial contribution to stem cell research;

It was already shown that stem cells laid on the connective tissue of the heart, the soft skeleton of the heart, can lead the entire formation of a new heart. Stem cells have this enormous regenerative potential. AI can take this to another level by helping establish the conditions in which this type of regeneration can be orchestrated inside the body.But we have to be grateful for what we already have, over the last 20 years, I have studied endogenous stem cell mobilization and today the fact that we have such amazing results with Stemregen is testament that regenerative medicine is already a success.

As AI continues to scale over industry boundaries, we can only sit back and hope it delivers on its full potential promise. Who knows? Perhaps AI really can change the world.

Gavreto is the first and only precision medicine approved in the EU for first-line treatment of people with RET fusion-positive advanced NSCLC

Conditional approval is based on results from the phase I/II ARROW study, in which Gavreto led to durable responses in people with RET fusion-positive advanced NSCLC

Basel, 19 November 2021 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the European Commission (EC) has granted conditional marketing authorisation for Gavreto (pralsetinib) as a monotherapy for the treatment of adults with rearranged during transfection (RET) fusion-positive advanced non-small cell lung cancer (NSCLC) not previously treated with a RET inhibitor. Gavreto is the first and only precision medicine approved in the European Union (EU) for the first-line treatment of people with RET fusion-positive advanced NSCLC.1

Todays approval represents an important step forward in delivering precision medicine to people with RET fusion-positive advanced non-small cell lung cancer, for whom treatment options have historically been limited," said Levi Garraway, M.D., Ph.D., Roches Chief Medical Officer and Head of Global Product Development. By using cancer genomic profiling upfront, healthcare professionals may identify specific genetic alterations that predict clinical benefit of targeted treatment options like Gavreto in the first-line setting.

The approval is based on results of the ongoing phase I/II ARROW study, in which Gavreto led to durable responses in people with advanced RET fusion-positive NSCLC.2 In 75 treatment-nave patients, Gavreto demonstrated an overall response rate (ORR) of 72.0% (95% CI: 60.4%, 81.8%), and median duration of response (DOR) was not reached (NR) (95% CI: 9.0 months, NR).2 In 136 patients who had previously received platinum-based chemotherapy, Gavreto demonstrated an ORR of 58.8% (95% CI: 50.1%, 67.2%), and median DOR was 22.3 months (95% CI: 15.1 months, NR).2 Gavreto was also generally well-tolerated, with a low rate of treatment discontinuation; common grade 3-4 adverse reactions were neutropenia (reported in 20.1% of patients), anaemia (17.6%) and hypertension (16.1%).2

Story continues

Approximately 37,500 people are diagnosed with RET fusion-positive NSCLC worldwide each year; the disease often affects people with minimal to no history of smoking, and who are typically younger than the average person diagnosed with lung cancer.3,4,5 Roche is committed to providing a tailored treatment option for every person with lung cancer, no matter how rare or difficult-to-treat their type of disease. Gavreto in RET fusion-positive advanced NSCLC, along with Alecensa (alectinib) in ALK-positive advanced NSCLC and Rozlytrek (entrectinib) in ROS1-positive advanced NSCLC, is part of Roches growing portfolio of precision medicines. Together, they offer personalised treatment options for almost one in ten people with advanced NSCLC, and biomarker testing is the most effective way to identify those people who may benefit.6

Beyond NSCLC, RET alterations are also key disease drivers in other cancer types, such as thyroid cancers. Gavreto has shown activity across multiple solid tumour types, reflecting tumour-agnostic potential.7 It is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adults with metastatic RET fusion-positive NSCLC, and for the treatment of adult and paediatric patients 12 years of age and older with advanced RET-altered thyroid cancers. Gavreto is also approved in Canada, mainland China and Switzerland. In the EU, a submission for RET-altered thyroid cancers is planned. Regulatory submissions for advanced RET fusion-positive NSCLC and RET-altered thyroid cancers are also underway in multiple countries worldwide.

Blueprint Medicines and Roche are co-developing Gavreto globally, with the exception of certain territories in Asia, including China.* Blueprint Medicines and Genentech, a wholly owned member of the Roche Group, are commercialising Gavreto in the US and Roche has exclusive commercialisation rights for Gavreto outside of the US, with the exception of certain territories in Asia, including China.*

About the ARROW study8ARROW is an ongoing phase I/II, open-label, first-in-human study designed to evaluate the safety, tolerability and efficacy of Gavreto, administered orally in people with rearranged during transfection (RET) fusion-positive non-small cell lung cancer (NSCLC), RET-mutant medullary thyroid cancer, RET fusion-positive thyroid cancer and other RET-altered solid tumours. ARROW is being conducted at multiple sites across the United States, Europe and Asia.

About rearranged during transfection (RET)-altered cancersRET gene alterations, such as fusions and mutations, are key disease drivers in many types of cancer, including non-small cell lung cancer (NSCLC) and several types of thyroid cancer. There are approximately 2.21 million cases of lung cancer diagnosed each year worldwide,3 of which approximately 1.8 million are NSCLC and RET fusions are present in approximately 1-2% of these patients,4,5 meaning RET fusion-positive NSCLC affects up to 37,500 people each year. Additionally, approximately 10-20% of people with papillary thyroid cancer (the most common type of thyroid cancer) have RET fusion-positive tumours,9 and roughly 90% of people with advanced medullary thyroid cancer (a less prevalent form of thyroid cancer) carry RET mutations.10 Oncogenic RET fusions also are observed at low frequencies in other cancers, including cholangiocarcinoma, colorectal, neuroendocrine, ovarian, pancreatic and thymus cancers.

About Gavreto (pralsetinib)Gavreto is a once-daily, oral precision medicine designed to selectively target rearranged during transfection (RET) alterations, including fusions and mutations, regardless of the tissue of origin. Preclinical data have shown that Gavreto inhibits primary RET fusions and mutations that cause cancer in subsets of patients, as well as secondary RET mutations predicted to drive resistance to treatment. Blueprint Medicines and Roche are co-developing Gavreto for the treatment of people with various types of RET-altered cancers.

About Roche in lung cancerLung cancer is a major area of focus and investment for Roche, and we are committed to developing new approaches, medicines and tests that can help people with this deadly disease. Our goal is to provide an effective treatment option for every person diagnosed with lung cancer. We currently have six approved medicines to treat certain kinds of lung cancer, and a pipeline of investigational medicines to target the most common genetic drivers of lung cancer, or to boost the immune system to combat the disease.

European Commission approves Roches Gavreto (pralsetinib) for the treatment of adults with RET fusion-positive advanced non-small cell lung cancer -...

COVID-19 has been all-consuming. For nearly two years, the world has been focused on the race for vaccines, the pressures on providers, the best testing protocols, and simply staying safe.

COVID-19 also slowed some research efforts, but scientists still managed to seek solutions for many other pressing concerns Alzheimers disease, maternal mortality, and prostate cancer among them that have bedeviled patients for decades.

Below are eight medical advances that may not have grabbed your attention but could ultimately improve the lives of millions.

Assessing a stroke demands a rapid, life-or-death assessment: Is the culprit a clot, which requires a blood thinner, or bleeding in the brain, which requires surgery? Now, a portable MRI device can help make that assessment right at a patients bedside and in much less time than required by a trip to a standard machine.

The Swoop MRI which was created with input from Yale Medicine in New Haven, Connecticut received Food and Drug Administration (FDA) approval in August 2020 and is already at work in several U.S. hospitals.

The new portable machine offers many advantages over its massive cousin, says Yale neurologist Kevin Sheth, MD.

The very strong magnets in regular MRIs bring a lot of challenges, he explains. You need intensive power and cooling, precautions like a shielded room, and a lot of training. If you use a weaker magnet, all those problems go away.

The weaker magnet is effective, according to an August 2021 study, which asked clinicians to identify various cerebral pathologies using Swoop images. The goal is not to be as good as a high-magnet MRI, but to be good enough for clinical decisions, says Sheth, who co-authored the study but has no financial interest in Hyperfine, the Connecticut-based company that produces the machine.

Swoops size its smaller than some refrigerators eliminates the need to move frail patients down hospital hallways. Whats more, its cost around $100,000 compared to $1 million for the bigger machine puts it within reach of hospitals and regions with fewer resources. This could essentially democratize brain imaging, argues Sheth.

Prostate cancer strikes 1 out of 8 U.S. men, and it is expected to take more than 34,000 lives this year alone. When it metastasizes, the disease is almost always incurable, leaving physicians focused only on postponing death and improving patients lives.

A promising new approach has succeeded at both goals and did so among men with an advanced form of the disease whose condition had deteriorated despite receiving standard treatments.

In fact, it more than doubled how long patients lived without their cancer worsening, according to a paper published in September. The study, which followed 831 men in 10 countries for a median of 20 months, compared patients who continued to receive standard care with ones who got the new treatment.

The treatments name is complex: lutetium-177-PSMA-617. But its approach is straightforward: Drive radiation directly into a cancer cell while sparing healthy tissue around it.

The method uses a compound called PSMA-617 to hone in on a protein found almost exclusively in prostate cancer cells, explains Oliver Sartor, MD, study co-lead investigator and medical director of Tulane Cancer Center in New Orleans. Then, a radioactive particle carried by the compound blasts the cancer cells, wherever they are.

Its like a little smart bomb, says Sartor.

In September, the FDA granted the treatment priority review status, according to drug manufacturer Novartis, which funded the study. An answer is expected in the first half of 2022.

Sartor feels hopeful. Ive been working in prostate cancer for more than 30 years, and this is the largest advance Ive ever been associated with.

For more than 5,000 years, sickle cell disease (SCD) has caused untold suffering in people of African descent. In patients with the genetic illness, red blood cells are not round but crescent-shaped like a sickle and can clog blood vessels, depriving the body of oxygen and causing tremendous pain. For a long time, the only cure has been a bone marrow transplant, but new gene-editing techniques now may offer a safe and effective alternative.

In research conducted at Boston Childrens Hospital, scientists used a virus to switch off the gene that triggers cells sickling, according to a January 2021 study. The patients subsequently produced healthy red blood cells and nearly all were able to discontinue the blood transfusions SCD often requires.

One participant used to have transfusions every month but has not needed any in three years, says David Williams, MD, chief of the Division of Hematology/Oncology at Boston Childrens and head of the research team. This has completely changed his life.

The study followed six patients for a median of 18 months and found that the treatment completely halted the diseases more severe symptoms.

Im so happy for my sickle-cell patients. This is a terrible disease, notes Williams.

Next up for Williams is a trial with 25 patients. Meanwhile, SCD researchers elsewhere are studying other gene-editing techniques. All these approaches look promising, and we need a lot more research to determine if one or another is better, Williams says.

This is a very exciting time. In the past, we havent had any particularly good treatments, and now we have several possibilities," he adds.

When a womans uterus fails to contract after childbirth, tremendous blood loss can ensue, possibly leading to an emergency hysterectomy or even death. In fact, postpartum hemorrhage affects 3% to 10% of all childbirths in the United States and causes more than one-third of childbirth-related maternal deaths worldwide.

Treatment options include medications that dont always work and inserting a balloon to put pressure on the uterus much like exerting pressure on a cut that comes with risks and must remain in place for a day.

But providers now have another option.

A new vacuum device aids natural post-birth contractions, putting pressure on leaking blood vessels. The FDA approved the device the Jada vacuum uterine tamponade in September 2020 following a 12-site research study.

The vacuum approach is very logical since its like what the body is supposed to do, says Dena Goffman, MD, the primary investigator at Columbia University Irving Medical Center in Manhattan. Also, the vacuum is used for less time than the balloon roughly two or three hours. For moms, thats a big deal because it makes it easier to breastfeed, get out of bed, and bond with their child, she adds.

The vacuum controlled bleeding in a median of three minutes and successfully treated 94% of participants, according to the study, which was funded by the devices manufacturer, Alydia Health. In comparison, other research puts the balloons effectiveness at 87%.

When a patient has a postpartum hemorrhage and youre the doctor at the bedside, its scary because you know how quickly things can deteriorate, says Goffman. Using this device, when you see the bleeding slowing quickly and you can feel the uterus contracting, its just incredible.

Tearing an anterior cruciate ligament (ACL) the flexible band inside the knee that helps stabilize it can upend a sports career and sideline weekend athletes. Between 100,000 and 200,000 ACL tears occur each year in the United States.

The most effective repair option has been removing the ruptured ACL, harvesting a graft from the shin or elsewhere, sewing that tissue into the knee, and hoping both surgical sites heal well.

In December 2020, the FDA approved a simpler, more natural method: the Bridge-Enhanced ACL Restoration (BEAR).

We basically stimulate the ACL to heal itself, says Martha Murray, MD, orthopedic surgeon-in-chief at Boston Childrens Hospital and BEARs creator.

The approach involves placing a protein-based sponge, prepared with some of the patients own blood, between the torn ACL ends. Murray explains that the blood promotes the connection of the two ACL pieces to the sponge and, ultimately, to each other.

So far, the approach has been tested on more than 100 patients. In a May 2020 study, patients and physicians reported that BEAR performed as well as the standard repair and without the graft surgery that can cause ongoing pain or weakness at the donor site. Miach Orthopaedics, which has the worldwide exclusive license for the BEAR implant, has already begun making it available through orthopedic surgeons in the United States.

For Murray, the experience has highlighted the value of serving as a physician-researcher. When youre faced with a patient with a problem and the current solution is imperfect, its great to be able to say, Were working on a better solution. Its incredibly gratifying.

For the first time since 2014, a new obesity medication has hit the market, offering hope to the 78 million Americans who face the many risks of excess weight: cancer, heart disease, diabetes, and complications from COVID-19, among others.

And the new medication semaglutide, also known as Wegovy is significantly more powerful than its predecessors, according to research that helped it garner approval from the FDA in June.

Weve seen 1 to 2 times the amount of weight loss compared to other medications, says Robert Kushner, MD, a researcher at Northwestern University Feinberg School of Medicine who has led semaglutide studies. That's a leapfrog advance.

In fact, semaglutide recipients lost nearly 15% of their body weight on average compared with 2.4% among controls, according to one study of nearly 2,000 patients.

Semaglutide an injectable medication is not entirely new. A synthetic version of a natural hormone that quells appetite, its already used to treat Type 2 diabetes. But the obesity trials, paid for by pharmaceutical company Novo Nordisk, used a much higher dose.

High doses havent been studied long enough to identify long-term side effects, notes Kushner, a paid consultant to Novo Nordisk. But the recent research reported mild-to-moderate gastrointestinal issues that lessened over time.

Now Kushner hopes semaglutide will help spark interest in obesity medications.

Over 40% of U.S. adults have obesity, and the number who are getting a pharmacologic treatment is under 3%, he says. Part of the challenge is educating primary care providers that providing evidence-based obesity care includes consideration of medication."

Randall Bateman, MD, a Washington University School of Medicine in St. Louis (WUSTL) neurologist, is thrilled to have contributed to the first blood test for Alzheimer's disease a devastating condition that affects as many as 5.8 million Americans.

Back in 2017, though, as Bateman geared up to share the discovery that would enable the test, he worried about his peers reaction. After all, scientists were convinced that the blood marker he studied couldnt predict the disease.

But the WUSTL method was much more sensitive and direct than prior approaches. The resultant test called PrecivityAD effectively detects the amyloid plaques that are a hallmark of Alzheimers disease and has proven as accurate as the previously used tools of a spinal tap or positron emission tomography (PET) scan, which are far more costly and complex.

The test, developed by a company called C2N Diagnostics that Bateman co-founded, has been available to physicians since October 2020, when it received approval through a federal lab certification program. It now awaits additional approval from the FDA.

Weve been hoping for a test to diagnose Alzheimers for more than 20 years, says Bateman, WUSTLs Charles F. and Joanne Knight distinguished professor of neurology. Currently, up to half of people with Alzheimers are misdiagnosed.

The road to success in science is paved with hard work and great uncertainty, he adds. Its a real gamble. Youre investing your life in this work, and you hope it will have a positive impact. And then its like, Wow, it worked!

Anger, fear, recurring nightmares, and intense flashbacks are among the many symptoms that can batter patients with post-traumatic stress disorder (PTSD). The condition, which affects about 15 million U.S. adults in a given year, can be extremely difficult to treat.

A potentially groundbreaking PTSD treatment now lies in a seemingly unlikely source: MDMA, better known as the illegal drugs ecstasy and molly that fueled all-night dance raves and caused potentially fatal side effects.

In June, a study in Nature Medicine reported that patients with severe PTSD combat veterans, first responders, and victims of sexual assault and mass shootings, among others experienced significant relief from MDMA.

In fact, two months after treatment, 67% of subjects who received MDMA together with talk therapy no longer qualified for a diagnosis of PTSD. I saw this amazing transformation in patients, says Jennifer Mitchell, PhD, the studys lead author and a University of California, San Francisco, School of Medicine neurology professor.

The treatment involved three eight-hour sessions a month apart during which patients ingested MDMA and processed painful memories and emotions in talk therapy.

MDMA releases a powerful supply of serotonin and stimulates hormones associated with emotional bonding, Mitchell explains. The idea is that it helps patients be open in a way that enables them to connect well with therapists and work through their problems more quickly.

Before the drug can receive FDA approval for PTSD, researchers need to complete one more clinical trial. Even if it succeeds, Mitchell is aware that MDMA still bears stigma from its party drug image.

I hope people are going to be open-minded and look at the data, which included no abuse potential or other serious side effects from MDMA as used in the study. We are talking about use in a controlled, therapeutic situation, she says. Using drugs recreationally is entirely different. Otherwise, people would come back from [the art and community event] Burning Man cured of their psychological issues.

Although stem cells are known to work wonders, there is still a lot of misunderstanding about what they are, what they do, and how they work.

The good news is that StemCells21 can clear everything up for you. SC21 produces all of its cellular medications in-house, and all of its treatments are performed at its cutting-edge medical centre in Bangkok. Its a one-stop shop that adheres to high-quality standards.

This company will be on display at the Thailand International Boat Show, which will be hosted at Royal Phuket Marina from January 6 to 9 next year. Staff from StemCells21 will be on hand to walk you through the producers, pricing, and techniques.

StemCells21s laboratory is a full-scale culture & analysis laboratory specialising in the production & treatment of Mesenchymal Stem Cells (StemCells21), and Natural Killer Cells (ImmuneCells21). It has also launched a new generation of regenerative medicine called Pluripotent Stem Cells (iPSC21), which hold great potential for impacting chronic diseases in the quest for anti-ageing.

The lab has seven scientists & stem cell researchers, a couple of who have worked with Professor Shinya Yamanaka, who was awarded the Nobel Prize in Physiology or Medicine in 2012 for the discovery that mature cells can be reprogrammed to become pluripotent (iPS cells).

Before StemCells21 was created, Managing Director Paul Collier and co-founder Sergei Dmitrievs experienced the power of stem cells either first hand or through the treatment of someone close to them. They knew that stem cells could deliver positive health results, and also knew stem cell treatmentsand the clinics that administered themhad room for improvement.

After deep laboratory investigation, they came to see that most clinics utilised relatively low-quality stem cells and incomplete treatments. While these clinics could deliver a certain level of positive results, they were only scratching the surface of the promise that stem cell treatments could deliver.

Furthermore, the clinics themselves frequently provided a less-than-ideal patient experience. Clinics were generally hectic, unprofessional, and unwelcoming. Patients were often administered a single treatment and sent on their way, unsure if they had experienced an efficacious treatment or if they had travelled and paid for nothing.

StemCells21 was created to offer superior results and give you a welcoming experience. It was set up to provide the global community with access to treatments that few people are aware of, and to offer health benefits that are superior to what most people ever imagined were possible.

The SC21 complex in Bangkok houses the StemCells21, ImmuneCells21, and IPS21 laboratories, as well as the premium 5* IntelliHealth+ (IH+) Clinic.

IntelliHealth+ is a state-of-the-art medical centre licensed by the Thai medical authorities. The luxurious design, efficient workflow layouts, and modern treatments make it the ideal choice for customers seeking a premium level of healthcare in 5* settings.

The centre treats patients from all over the world and has staff who speak fluent English, Arabic, Chinese, Russian, Thai and Spanish.

Furthermore, SC21s come from all corners of the globe for these cutting edge treatments. Many VIPs travel to the clinic including presidents, prime ministers, sports stars, football managers, bank owners and heads of major corporations, many of whom return every six to twelve months and have been doing so for years.

Recently, SC21 treated a ten-year-old British boy who had Ewing sarcoma develop in his arm, which then spread to other areas. He had tried every treatment option in the UK. His trip and treatment were sponsored by UK football teams and the public. Since he started treatment hes put on weight, hes vibrant, and his demeanour has totally changed. Various tests and scans have shown he is responding very well to the immunotherapy course and will perform another round in a few months time.

SC21 focuses on three main areas: anti-ageing and longevity; orthopaedic and muscular-skeletal issues (knee, hip, back & shoulder); and chronic diseases (diabetes, liver cirrhosis, lung, respiratory, hearing & vision disorders). Aside from that, the clinic can also help with chronic fatigue and burn-out syndrome.

Outpatient services for anti-ageing, immunotherapy and regenerative medicine are available at the centre. The anti-ageing clinic has a cutting-edge approach to skin rejuvenation, dermatology, detoxification, and wellbeing. A youthful appearance, more energy, improved mental capacity and mobility, reduced aches and pains, and a stronger immune system are among the benefits.

The high level of traditional medicine and the unique protocols designed by the IH+ teams give patients real therapeutic benefits and longevity.

According to Paul Collier, a client typically receives two sessions of stem cell injections during a treatment intravenous for systemic and local to the target and is required to stay in Bangkok for two days following their procedure to monitor any complications that may arise. Then theyre given a two-month take-home kit that comprises self-administered injections (similar to insulin) that target specific growth factors in organs or tissues that need to be repaired. These can also be taken orally, but they are less effective.

He goes on to say that stem cells are the foundation of the human body. They split over and over to produce humans from an embryo at the start of our lives. They restore cells in your blood, bone, skin, and organs throughout your life to keep you alive and functioning. Stem cells have two distinct properties that distinguish them from other types of cells in our bodies.

First, they can self-renew (mitosis), which is a stage of the cell cycle in which replicated chromosomes are divided into two new nuclei. As a result, identical duplicated cells are produced.

Secondly, they have the ability to differentiate into specialized cells such as cartilage, heart cells, liver cells, and neurons. No other cell in the body has the natural ability to generate new cell types.

Mesenchymal Stem Cells (MSCs) are at the core of StemCells21s regenerative programs. They are multipotent stem cells derived from various adult and fetal tissues. A large number of studies have shown the beneficial effects of MSC-based therapies to treat different pathologies, including neurological disorders, cardiac ischemia, diabetes, and bone and cartilage diseases.

StemCells21 also has arthritis treatment, which reduces inflammation & joint pain, increases cartilage growth, improves mobility & joint stability and lessens dependence on medication. The clinics degenerative spine treatments help discs regenerate and stabilize the spine.

On top of that, it provides lung & liver disease treatment as well as treatments for autism, cerebral palsy, diabetes, motor neuron disease, multiple sclerosis and immune disorders.

Theres even eye treatment, which reduces blurred vision & field of vision defects, improves night vision & enhances colour texture.

SC21 can even help with certain types of cancer by taking a clients blood and growing their natural killer cells (immunotherapy) over a 21-day period. Through various stimuli, their cytotoxicity is increased which kills cancer and virally-affected cells.

Paul says stem cell therapy should be looked at before undergoing any kind of invasive surgery. The type of medicine should certainly be an intervention before surgery. If you are looking at knee replacement, why not consider an injection of a biologic that would only take a couple of days and has the potential to remodel the cartilage, because once you perform surgery there is no going back.

SC21 also produces a wide range of stem-cell extract-based cosmetics and nutritional supplements, which are available at their medical centres and online under the brand SC21 Biotech.

The Thailand International Boat Show will feature Paul Collier and his team. Theyll be able to answer any of your questions about the cost, procedure, and treatment. On top of that, they will also assist you in educating yourself and managing your expectations so that you do not expect more than stem cell therapy can provide. If you want to get treatment, they will also provide you with a complete report on all treatments. SC21 is fully compliant with international regulations and guidelines.
