This study is done by isolation of chicken X-stage blastodermal cells. The putative ES cell clone features a typical bird’s nest structure, PAS and AKP-positive and strongly positive for SSEA-1. It is able to form embryoid bodies and multiple types of cells as well as participates in embryonic development and feather color chimera formation through in vitro differentiation.
