Controlling Adult Stem Cells

Filed under: Uncategorized — chelseaz @ 9:50 pm

At the UK National Stem Cell Network Annual Science Meeting atendees heard about the promise of adult stem cells. Yes, you heard that right, the promise of ASCs, not that embryonic stem cell hype (which I’m sure was also present at the meeting). From the story:

Professor Kielty’s team study stem cells that are found in human bone marrow called mesenchymal stem cells (MSCs). MSCs have the ability to relocate and develop into several different types of cells and tissue and are very promising as a source of cells for transplant in tissue repair. As well as offering the potential for bespoke treatments derived from a person’s own cells, MSCs are unlikely to trigger a severe immune response, and may be suitable for “off-the-shelf” treatments for tissue repair. This research focuses on the details of a messaging system that leads to the development of blood vessels from MSCs in the body. This system is called ‘PDGF receptor signalling’…

Professor Kielty said: “What we have shown is that adult stem cells respond in particular ways to some of the chemical signals in the body. The next stage will be to understand how this messaging system regulates relocation of the MSCs and instructs them to become blood vessel cells. After that, we can look at applying our understanding to develop stem-cell derived therapies for tissue repair.”

Here again we see how modern stem cell science is debunking the theory that ASCs have little to no pluripotency. In fact, because of their maturity, it is easier for ASCs to conform to their surroundings. ESCs have generally proved to be too pluripotent, hence their tendency to form tumors.
