A HEALTHCARE worker at Royal Bournemouth Hospital has donated stem cells in a bid to save the life of an unknown man.

Claire Waugh, pictured, who has always been a regular blood donor, decided to join the Anthony Nolan stem cell register after her father was diagnosed with prostate cancer three years ago.

The healthcare assistant co-ordinator was later identified as a possible match for a man needing life-saving treatment.

Following rigorous testing Claire was visited by nurses from the blood cancer charity, who gave her three injections every day for three days to stimulate her bone marrow to produce stem cells.

On the fourth day she travelled to Kings College Hospital in London to receive a final set of injections and undergo a stem cell collection in a simple five-hour outpatient procedure, which is similar to giving blood.

Claire said: I couldnt move or bend my arm due to the fairly heavy duty needle, but I was looked after really well so in the end the time went very quickly.

After donating, Claires stem cells were rushed to the recipient within the required 72 hours. A volunteer from Anthony Nolan told me that if he doesnt survive, there is nothing else on this earth that would have cured him, so this was this persons last chance, added Claire.

When my dad was poorly it made me think that if he needed this kind of help, I would be praying every night that someone would help him.

By doing this, it meant that I could give that chance to someone else and their family.

Royal Bournemouth Hospital granted special leave to Claire for the donation with the charity covering all of her and her husbands travel expenses.

Despite previous indications to the contrary, the esophagus does have its own pool of stem cells, said researchers from the University of Pittsburgh School of Medicine in an animal study published online today in Cell Reports. The findings could lead to new insights into the development and treatment of esophageal cancer and the precancerous condition known as Barrett's esophagus.

According to the American Cancer Society, more than 18,000 people will be diagnosed with esophageal cancer in the U.S. in 2014 and almost 15,500 people will die from it. In Barrett's esophagus, the lining of the esophagus changes for unknown reasons to resemble that of the intestine, though gastro-esophageal reflux disease or GERD is a risk factor for its development.

"The esophageal lining must renew regularly as cells slough off into the gastrointestinal tract," said senior investigator Eric Lagasse, Pharm.D., Ph.D., associate professor of pathology, Pitt School of Medicine, and director of the Cancer Stem Cell Center at the McGowan Institute for Regenerative Medicine. "To do that, cells in the deeper layers of the esophagus divide about twice a week to produce daughter cells that become the specialized cells of the lining. Until now, we haven't been able to determine whether all the cells in the deeper layers are the same or if there is a subpopulation of stem cells there."

The research team grew pieces or "organoids" of esophageal tissue from mouse samples, and then conducted experiments to identify and track the different cells in the basal layer of the tissue. They found a small population of cells that divide more slowly, are more primitive, can generate specialized or differentiated cells, and have the ability to self-renew, which is a defining trait of stem cells.

"It was thought that there were no stem cells in the esophagus because all the cells were dividing rather than resting or quiescent, which is more typical of stem cells," Dr. Lagasse noted. "Our findings reveal that there indeed are esophageal stem cells, and rather than being quiescent, they divide slowly compared to the rest of the deeper layer cells."

In future work, the researchers will examine human esophageal tissues for evidence of stem cell dysfunction in Barrett's esophagus disease.

"Some scientists have speculated that abnormalities of esophageal stem cells could be the origin of the tissue changes that occur in Barrett's disease," Dr. Lagasse said. "Our current and future studies could make it possible to test this long-standing hypothesis."
