Figure 1. Xenogeneic offspring from guinea fowl.

Figure 1

Upper panel: Phylogenetic relationship between chicken (Gallus domesticus) and guinea fowl (Numida meleagris). Bottom panel: primordial germ cells migrating through the blood in a 2.5 day old embryo were retrieved and cultured (A) and transfected with a GFP expression construct. GFP positive PGCs (B) were injected into guinea fowl embryos (C). The embryos were hatched (D) and males were raised to sexual maturity (E). The guinea fowl males were mated to White Leghorn females (F) and GFP positive chicken offspring (G) were obtained demonstrating that the chicken PGCs had passed through the germline of the male guinea fowl.
