These cells exhibit features similar to those of chicken EG cells such as typical bird nest morphology, strong reactivity toward periodic acid-Schiff and alkaline phosphatase staining. They could be maintained for more than a month on STO feeder in vitro, expressed the pluripotent markers such as stage specific embryonic antigen-1, stage-specific embryonic antigen-4, tumor rejection antigen-1-60 and tumor rejection antigen-1-81. Furthermore, the ES-like cells could form embryoid bodies and differentiate to several kinds of cells in vitro. Their easy accessibility makes these cells an attractive alternative to chicken ES cells for future functional and genomic studies and comparison with other stem cells.
