No colonies were observed within 30Â days in the hAESC group. HepG2 cells were used as a positive control. b Tumorogenesis in NOD-SCID mice. There was no any tumor formation after 5Â months of hAESC injections, in which the cells were injected into the right back and left thigh muscle of NOD-SCID mice. Embryonic stem cells were used as a positive controlBack to article page
