Research Abstract

Human embryonic stem(ES) cells are difficult to be cultivated in vitro, compared with murine ES cells. In contrast, human embryonal carcinoma(EC) cells can easily be cultivated, compared with human ES cells. In this study, we evaluated human EC cell lines to investigate which human cells can be used as feeder cells. We set specification of human feeder cells in terms of maintenance of human ES cells and preservation of pluripotency. We determined human cell types that are capable of being feeder cells and indeed established human feeder cells.
