Re: Cloning and Telomerase

... shortening chromosomes that eventually can’t function normally. One of the steps required for the in vitro immortalization of cell lines is the de-repression of telomerase to enable the telomeres to be continually restored. They are learning how to do more with differentiated cells. Recently, there ...
