Most ECC lines are aneuploid and contribute only poorly to adult somatic tissues and rarely to the germline upon injection into blastocysts and subsequent transfer into foster females, a key assay to probe the ability of nonhuman pluripotent cell lines to functionally integrate into tissues of the developing embryo.The finding that ECCs can also be derived from teratocarcinomas experimentally induced by the transplantation of implantation-stage mouse embryos to extrauterine+ q- x( T( F+ @; j

对于 ECCs 【immortal pluripotent cell lines from teratocarcinomas, tumors of germ cell origin-- embryonal carcinoma cells 】不太懂…………
