Induction of hematopoiesis in an embryonic germ (EG) cell line derived from mouse primordial germ cells (PGCs) was examined. When single undifferentiated EG-1 cells were inoculated directly into the methylcellulose medium, both primitive and definitive erythropoiesis were seen in embryoid bodies derived from the EG cells as observed in ES cells, and production of myeloid cell lineages was stimulated by IL-3. These results indicate that EG cells acquired in vitro potency to differentiate toward hematopoietic cells, although they were derived from PGC and are distinct from inner cell mass-derived ES cells with regard to gene expression and patterns of DNA methylation corresponding to genomic imprinting. It turns out that they are useful for study of cell differentiation in the animals whose ES cells are not available.
