Stem Cell Research
Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state
July 6th, 2007
For more than 25 years, stem cells have been defined based on what they can become: more of themselves, as well as multiple different specialized cell types. But as genetic techniques have become increasingly powerful, many scientists have sought a more molecular definition of stem cells, based on the genes they express. Now, a team of Canadian scientists has identified 1,155 genes under the control of a gene called Oct4 considered to be the master regulator of the stem cell state. A comprehensive molecular definition of stem cells is emerging: according to this research, stem cells are cells that keep their DNA packaged in a flexible format, keep cell division tightly...
