title: Cells derived from human umbilical cord blood support the long-term growth of undifferentiated human embryonic stem cells.
abstract: Various types of human cells have been tested as feeder cells for the undifferentiated growth of human embryonic stem cells (hESCs) in vitro. We report here the successful culture of two hESC lines (H1 and H9) on human umbilical cord blood (UCB)-derived fibroblast-like cells. These cells permit the long-term continuous growth of undifferentiated and pluripotent hESCs. The cultured hESCs had normal karyotypes, expressed OCT-4, SSEA-4, TRA-1-60, and TRA-1-81, formed cystic embryonic body in vitro and teratomas in vivo after injected into immunodeficient mice. The wide availability of clinical-grade human UCB makes it a promising source of support cells for the growth of hESC for use in cell therapies.
