Scientists find key embryonic stem cell gene
Scientists have identified a gene that is required during early mammalian embryogenesis to maintain cellular pluripotency – the ability of an embryonic cell to develop into virtually any cell type of the adult animal. This discovery by Dr. Robin Lovell-Badge and colleagues at the MRC National Institute for Medical Research (London, UK) that the Sox2 gene is necessary to sustain the developmental plasticity of embryonic cells sheds new light on the molecular cues that direct early embryogenesis, as well as the genetic requirements for embryonic stem cell maintenance. The report is published in the January 1 issue of Genes & Development.
"Stem cells must have specific genes that give them their characteristic properties. Our work describes one such gene, Sox2, that appears essential for multipotent stem cell types in the early embryo," explains Dr. Lovell-Badge.
