A corporation in New York, called NeoStem Inc., focuses on processing long-term storage of adult stem cells. They do this by collecting and storing non-diseased stem cells for future use. Early February saw this corporation announcing that they had received a provisional license for such tissue procurement services within the state of New York.

Recently, a patient in Finland was able to enjoy the benefits of the new jawbone that was cultivated from his own stem cells. The 65-year-old patient had suffered severe tissue damage due to tumor growth, but was able to undergo a bone transplant using stem cells that had been isolated from tissues grown inside his abdomen. Researchers in Finland, determined to isolate stem cells from a patient's own store of fat, grew them for two weeks in a mixture that also incorporated the patient's own blood serum. Later, they were successful in pulling out what they termed mesenchymal stem cells, which are immature cells that may be grown to form blood vessels, muscle tissues, as well as bone tissue.

Scientists and researchers have been searching for pancreatic stem cells for years. Because they were so difficult to find as well as to process and activate, most scientists have given up on the search. It was believed that finding and using pancreatic adult stem cells that replace beta cells that have been damaged in people suffering from diabetes might discover the reverse in the disease process. As it stands, there is no cure for Type-1 diabetes, except the possibility of transplanting pancreatic cells into the liver. The problem with this technique is that it takes several deceased donors to contribute the number of cells that are necessary for such a treatment.

While many of us are aware of the benefits of eating properly, recent research has identified the importance of carbohydrates in stem cell development. A carbohydrate molecule known as heparin sulfate is known to cover the surface of certain proteins on a cellular surface and is important for the potency, as well as the growth of stem cells. While the molecular function and mechanisms of such cells are still relatively unknown, such research offers potential as a jumping off point for further studies.

The headlines are screaming with the news that a toddler who had been suffering from a rare form of cancer has been saved by being given a transplant from stem cells saved from a Japanese woman's umbilical cord blood stem cells. The two-year-old British toddler had been given less than a 40% chance of survival after most of Europe and America have been scoured for suitable tissue donors in the hopes of providing a turnaround for the toddler's chances of survival. Unbelievable as it may seem, physicians discovered a perfect match for the toddler among stem cells that had been harvested and stored from the umbilical cord blood of a mother in Tokyo, Japan.

Melanoma is one of the most aggressive and devastating types of skin cancer. Scientists at Harvard have released a report that this type of human skin cancer has the potential to be suppressed by targeting cancer stem cells. Initial studies using mice found that specifically targeted cancer stem cells do have the ability to be suppressed. To date, there is no known cure for melanoma, one of the most aggressive skin cancers. In the United States alone, almost 60,000 new cases are diagnosed a year, and the National Cancer Institute states that nearly 8000 deaths in 2007 alone were caused by melanoma skin cancer.
