Scientists have made a fundamental discovery about how the properties of embryonic stem cells are controlled. The study, which focuses on the process by which these cells renew and increase in number, could help research to find new treatments. Researchers have found that a protein, which switches on genes to allow embryonic stem cells to self-renew, works better when the natural occurring level of the protein is reduced. It was previously thought that once levels of this protein - called Oct 4 - were reduced the numbers of new stem cells being produced would also fall... via Health News from Medical News Today Read More Here..
