Vitronectin (VTN-N) is a recombinant human protein that provides a defined surface for feeder-free culture of human pluripotent stem cells (PSCs). When used with Essential 8? Medium (A1517001), vitronectin (VTN-N) has been proven to maintain pluripotency and normal growth characteristics in multiple PSC lines. In addition, vitronectin (VTN-N) has been shown to support PSC growth for >50 passages without any signs of karyotypic abnormalities and to maintain the ability of PSCs to differentiate into all three germ line lineages. As published by Guokai Chen et al. (1) in the laboratory of James Thomson, the VTN-N variant of vitronectin supports human pluripotent stem cell attachment and survival better than wild-type vitronectin when used in conjunction with Essential 8? Medium
