Derivation of human trophoblast stem cells from placentas at birth.

ABSTRACT: Human trophoblast stem cells (hTSCs) have emerged as a powerful tool for modeling the placental cytotrophoblast (CTB) in vitro. hTSCs were originally derived from CTBs of the first-trimester placenta or blastocyst-stage embryos in trophoblast stem cell medium (TSCM) that contains epidermal growth factor, the glycogen synthase kinase-beta inhibitor CHIR99021, the transforming growth factor-beta inhibitors A83-01 and SB431542, valproic acid, and the Rho-associated protein kinase inhibitor Y-27632. Here, we show that hTSCs can be derived from CTBs isolated from the term placenta, using TSCM supplemented with a low concentration of mitochondrial pyruvate uptake inhibitor UK5099 and lipid-rich albumin (TUA medium). Notably, hTSCs could not be derived from term CTBs using TSCM alone, or in the a
