  • METHOD FOR EFFICIENT TRANSFER OF HUMAN BLASTOCYST-DERIVED STEM CELLS (hBS CELLS) FROM A FEEDER-SUPPORTED TO A FEEDER-FREE CULTURE SYSTEM
    Publication number: 20100183566
    Abstract: Technology is provided for the transfer of human blastocyst-derived stem cells (hBS cells) to a feeder-free culture system and propagation of the cells in such a feeder-free culture system, the method comprising the following steps of (a) transferring the blastocyst-derived stem cells from feeder to feeder free culture by mechanical treatment, (b) culturing the blastocyst-derived stem cells under feeder cell free growth conditions in a suitable growth medium and/or on a suitable support substrate, and (c) optionally passaging the blastocyst derived stem cell line every 3-10 days by enzymatic and/or mechanical treatment. The application of hBS cells cultured under a feeder-free condition in medicine (e.g., myocardial regeneration) and screening and toxicity testing also is provided.
