WebJan 3, 2013 · From a genetic standpoint, the life of any somatic cell lineage lasts a single generation, whereas the germ line is essentially immortal. Therefore, to ensure faithful transmission of genetic information between generations, it is much more important for germline cells to maintain genetic integrity than it is for somatic cells to do so. WebStem cells have the ability to self-renew. Unlike muscle cells, blood cells, or nerve cells—which do not normally replicate— stem cells may replicate many times. When a stem cell divides, the resulting two daughter cells may be: 1) both stem cells, 2) a stem cell and a more differentiated cell, or 3) both more differentiated cells.
