Sequential genetic modification of the hprt locus in human ESCs combining gene targeting and recombinase-mediated cassette exchange.


Genetic modification of human embryonic stem cells (hESCs) will be an essential tool to allow full exploitation of these cells in regenerative medicine and in the study of hESC biology. Here we report multiple sequential modifications of an endogenous gene (hprt) in hESCs. A selectable marker flanked by heterospecific lox sites was first introduced by… (More)
