The Senescence-Related Mitochondrial/Oxidative Stress Pathway is Repressed in Human Induced Pluripotent Stem Cells
Embryonic stem cells possess the ability to propagate in tissue culture indefinitely. This is different than differentiated cells, for example, skin cells which can only multiple in tissue culture approximately 50 times before undergoing senescence. The ability of embryonic stem cells to escape senescence is related to expression of the protein telomerase. Usually when cells…
