Stem cells are special human cells that are able to develop into many different cell types. This can range from muscle cells to brain cells. In some cases, they can also fix damaged tissues. Researchers believe that stem cell-based therapies may one day be used to treat serious illnesses such as paralysis and Alzheimer disease.

Stem cells are divided into 2 main forms. They are embryonic stem cells and adult stem cells.

Embryonic stem cells. The embryonic stem cells used in research today come from unused embryos. These result from an in vitro fertilization procedure. They are donated to science. These embryonic stem cells are pluripotent. This means that they can turn into more than one type of cell.

Adult stem cells. There are 2 types of adult stem cells.One type comes from fully developed tissues such as the brain, skin, and bone marrow. There are only small numbers of stem cells in these tissues. They are more likely to generate only certain types of cells. For example, a stem cell that comes from the liver will only make more liver cells.

The second type isinduced pluripotent stem cells. Theseare adult stem cells that have been changed in a lab to be more like embryonic stem cells. Scientists first reported that human stem cells could be changed in this way in 2006. Induced pluripotent stem cells don't seem to be different from embryonic stem cells, but scientists have not yet found one that can develop every kind of cell and tissue.

The only stem cells now used to treat disease are hematopoietic stem cells. These are the blood cell-forming adult stem cells found in bone marrow. Every type of blood cell in the bone marrow starts as a stem cell. Stem cells are immature cells that are able to make other blood cells that mature and function as needed.

These cells are used in procedures such as bone marrow transplants. These help people with cancer make new blood cells after their own hematopoietic stem cells have been killed by radiation therapy and chemotherapy. They may also be used to treat people with conditions such as Fanconi anemia. This is a blood disorder that causes the body's bone marrow to fail.

Stem cells may help your health in the future in many ways and through many new treatments. Researchers think that stem cells will be used to help create new tissue. For example, one day healthcare providers may be able to treat people with chronic heart disease. They can do this by growing healthy heart muscle cells in a lab and transplanting them into damaged hearts. Other treatments could target illnesses such as type 1 diabetes, spinal cord injuries, Alzheimer disease, and rheumatoid arthritis. New medicines could also be tested on cells made from pluripotent stem cells.

Stem cells need much more study before their use can be expanded. Scientists must first learn more about how embryonic stem cells develop. This will help them understand how to control the type of cells created from them. Another challenge is that the embryonic stem cells available today are likely to be rejected by the body. And some people find it morally troubling to use stem cells that come from embryos.

Scientists also face challenges when using adult pluripotent stem cells. These cells are hard to grow in a lab, so researchers are looking into ways to improve the process. These cells are also found in small amounts in the body. There is a greater chance that they could contain DNA problems.

Clinical trials that use stem cell therapies are currently being done in the U.S. If you are interested in trying this therapy to treat a certain condition, ask your healthcare provider how to find out about trials available in your area.

Stem Cells Market to Cross US$ 25.68 Bn by 2028, Increasing Demand for Stem Cells in Regenerative Medicines Accelerates Market Growth - BioSpace

An investigative stem cell-based therapy called PEC-Direct, designed to act as a replacement pancreas, has the potential to provide blood sugar control in patients with high-risk type 1 diabetes, suggests a clinical study presented Saturday, June 11at ENDO 2022, the Endocrine Societys annual meeting in Atlanta, Ga.

The study found multiple patients using the new treatment had clinically relevant increases in C-peptide, a substance made in the pancreas along with insulin. C-peptide and insulin are released from the pancreas at the same time and in about equal amounts, so measuring C-peptide can show how much insulin the body is making.

This research represents the first instance in multiple patients of clinically relevant increases in C-peptide, indicative of insulin production, with a stem cell-based therapy delivered in a device, according to Manasi Sinha Jaiman, M.D., M.P.H., Chief Medical Officer of ViaCyte, Inc., in San Diego, Calif., the company that makes PEC-Direct.

Patients with type 1 diabetes eventually lose the ability to produce their own insulin to control blood sugar levels. Patients must frequently check those levels with finger sticks, inject multiple insulin shots or carry around bulky devices. The injection of insulin also carries the risk of accidentally lowering blood sugar to dangerous levels.

The PEC-Direct device is designed to provide a long-term, stable source of insulin to regulate glucose levels. The device comprises a pouch containing stem-cell derived pancreatic cells which mature into insulin-producing cells once implanted into the body to regulate glucose levels. The open device membrane allows blood vessels to grow into the device to contact the cells. To prevent an immune reaction, patients take immunosuppressive drugs.

The treatment is meant for patients with high-risk type 1 diabetes, who may be especially vulnerable to acute complications due to factors such as recurrent severe low blood sugar, or frequent and extreme blood sugar fluctuations that are difficult to control.

The study included 10 adults with type 1 diabetes who had received their diagnosis at least 5 years prior to the start of the study and were not able to tell when their blood sugar went too low (called hypoglycemia unawareness). Initial data from one patient showed clinically relevant levels of stimulated C-peptide and corresponding improvements in blood glucose control within six months after implantation of PEC-Direct. Since then, increased C-peptide levels were seen in multiple patients, along with decreases in HbA1C (a blood test that measures average blood sugar levels over the past three months) by as much as 1.5%, and decreases in the amount of insulin patients needed to administer by as much as 70%.

The results suggest stem cell-based replacement therapy has the potential to provide blood glucose control and could one day eliminate the need for injecting or dosing insulin externally, Jaiman said. The study provides further proof-of-concept that continued optimization of PEC-Direct has promise as a functional cure for type 1 diabetes.

Stem-cell based therapy shows promise in treating high-risk type 1 diabetes - EurekAlert

MARSHALL, Ill. (WAWV/WTWO) A young Illinois woman welcomed the man that saved her life from across the world into her hometown.

Stem Cell Recipient 21-year-old Taylor Mason has had anything but a normal life, at 15-years-old she was diagnosed with Acute Myeloid Leukemia. After months of treatment and remission the Leukemia came back when she was 17.

They told me I needed a stem cell transplant so I did pre chemo, IVF fertility, and then I did a stem cell transplant, Mason said. All I was told is that it was from a donor in Europe.

Around the same time Stem Cell Donor Daniel Riedinger of Germany just happened to sign up to be a donor. After many tests he was notified he would be the best possible donor for Masons transplant, who he did not know at the time.

I was registered and I knew there was someone that needed my stem cells who would not survive without them, Riedinger said. It was not a question for me.

Mason had to wait two years in the registry and once she was well enough after her transplant she reached out to Reidinger.

I thought about what ones says and what one does for the person that saves your life for awhile, Mason said. Simply just hugging them and meeting them and knowing they are the reason your here is everything.

Mason visited Riedinger in Germany last year however, this is Riedingers first time in Masons hometown. Friends and family of Mason gathered at the Marshall VFW to meet Riedinger.

I now have a new sister and a new family, Riedinger said. I cant explain its unbelievable.

Mason said Riedinger has become a huge part of her life.

Hes a big part of our lives now I mean every holiday we contact him or he contacts, Mason said. We are family I mean we are literally blood now.

Both Riedinger and Mason encourage those considering stem cell donation to sign up.

Magdalena Zernicka-Goetz, Bren Professor of Biology and Biological Engineering and affiliated faculty member with Caltech'sTianqiao and Chrissy Chen Institute for Neuroscience, has been awarded the 2022 NOMIS Distinguished Scientist and Scholar Award. Established in 2016, the award is presented to "pioneering scientists and scholars who, through their innovative, groundbreaking research, have made a significant contribution to their respective fields and who inspire the world around them," according to the NOMIS Foundation.

Zernicka-Goetz's research addresses fundamental questions about how life begins, such as: What drives a fertilized egg to divide and grow until it becomes 40 trillion cells, and how do these cells know how to make a person? To address these questions, she has developed methods for tracking living embryos to determine how stem cells are first created, establish their fates, and work together to shape the body. She also pioneered methods to grow embryos beyond implantation, techniques that won the "People's Choice Scientific Breakthrough of the Year" in 2016 inSciencemagazine. Her team used these methods to createthe first complete embryo models from stem cells that develop like natural embryos.

In 2021, the team determined the molecular signals involved in how an embryo becomesasymmetrical and polarizedand how the embryo forms itshead-to-tail body axis.

Zernicka-Goetz received her PhD from Warsaw University and joined the Caltech faculty in 2019. Prior to Caltech, she was professor of mammalian development and stem cell biology at the University of Cambridge, England. She is a fellow of the British Academy of Medical Science, the Polish Academy of Sciences, and a recipient of anNIH Director's Pioneer Award and the 2022 Edwin G. Conklin Medal from the Society for Developmental Biology.

Zernicka-Goetz Receives Honors from the NOMIS Foundation - Caltech

An Australian-first study has found collecting and storing cells from a babys umbilical cord and later transferring them to a sibling who has cerebral palsy has been found to be safe.

The clinical trial, led by theMurdoch Childrens Research Institute (MCRI)and published inCytotherapy, stated fully matched umbilical cord blood cells from one child could safely be infused into a sibling with cerebral palsy. The study was funded by the Cerebral Palsy Alliance Research Foundation and Cell Care cord blood bank.

Only one serious adverse reaction related to the study was reported, while sixof the 12 participants experienced minor adversereactions. All adverse reactions were treated effectively in hospital.

Murdoch Childrens researcherDr Kylie Cromptonsaid while there was no cure for cerebral palsy, cord blood cells have the potential to improve brain injury and gross motor function because of their ability to activate repair processes and regenerate some tissues in the human body.

Our study found infusing matched sibling cord blood cells into children with cerebral palsy is a relatively safe procedure however it should only be conducted in tertiary hospitals with facilities to treat the infrequent adverse reactions, she said.

The phase I clinical trial involved 12 participants, aged 1-16 years, from across Australia who received a siblings cord blood cells and was followed up for 12 months after the infusion.

Most of the participants, monitored for a year, showed typical developmental progress for children with cerebral palsy, Improvements in gross motor function were noted in three children, three months after the infusion. Any changes were less pronounced one year afterwards.

Dr Crompton said the greatest gross motor improvements were seen in younger children who had not yet reached 90 per cent of their predicted gross motor skill potential.

This suggests that intervention may be more effective in the first few years of life, she said. To find outifthis is the case, we and other researchers are now planning additional trials to understand these effects better.

Cerebral palsy is caused by damage to the developing brain while in utero, during birth or in the first years of life. The congenital disorder affects around two per 1000 live births across the world, making it the most common physical disability in childhood. An Australian child is born with cerebral palsy every 20 hours.

Murdoch ChildrensProfessor Dinah Reddihoughsaid the findings were a valuable stepping-stone towards establishing the safety and feasibility of using umbilical cord blood in the management of cerebral palsy. However, not all children with cerebral palsy will have fully matched siblings cells available.

Investigating a cell product that is available to the broader cerebral palsy community, rather than just those with matched siblings who have cord blood stored, is an important next step, she said.

Further research is also needed to investigate whether different forms of cerebral palsy are more amenable to change following cord blood cell infusion, what cell dose is required and if multiple doses would provide a better outcome.

Diagnosed with cerebral palsy, Charlotte (pictured, right)at age two couldnt grip a water bottle or pen, verbally communicate and was yet to take her first steps. After taking part in the trial, mum Laura West said it was like a light switch had been turned on.

However, Laura said Charlottes developmental progression had slowed over time since the infusion.

While pregnant with her youngest daughter, Emma (pictured with Charlotte, below, left), Laura decided to collect and store cells from her umbilical cord to have them later transferred to Charlotte. Laura accessedCell Carescord blood collection and storage program for siblings of a child with cerebral palsy. The free program ensures these stem cells are collected in a fully audited and government-approved manner so that they will be available for use in future clinical trials in Australia.

Laura said the changes in Charlotte, now aged seven, were evident after starting the cell infusion.

Charlotte was quite static in her development and progress up until the infusion and then we saw this noticeable difference, she said.

It was striking at first and then settled into a steady improvement. Charlotte was always fed through a tube but quickly learned to drink out of a bottle. We never thought she would be able to grip a pencil properly but then suddenly she was holding it correctly.

She went from being propped up with pillows to sitting, standing and running. It was huge to see her so independent and able to do these things by herself. The rate of change in Charlotte in the immediate aftermath was so pronounced but now her development has slowed to baby steps.

Were glad the researchers will continue the work to see if the intervention may be more effective in the first few years of life, which will offer hope to other families.

Professor Nadia Badawi,Cerebral Palsy AllianceChair of Cerebral Palsy Research at The University of Sydney, said this was a landmark study, which gave a new understanding of how umbilical cord blood cells might one day be used to improve the lives of children with the disorder.

We are indebted to the children and their families who participated in this research, and who have helped to pave the way for many future trials, she said.

At Cerebral Palsy Alliance, we are committed to carrying out research that empowers people with cerebral palsy and their families. From surveying our community, we know that people with cerebral palsy and their families want more research into potential therapies, and this study is an important step forward in demonstrating the safety of using cord blood cells in an Australian hospital setting.
