Hematopoietic potential of yolk sac cells with various genotypes. Yolk sac cells collected at E9.5 were subjected to in vitro liquid culture with KL, IL-11, IL-3, and Epo. Hematopoietic cells grown after 10 days in culture were cytocentrifuged onto slides and stained with May-Grünwald/Giemsa. The arrow points to mast cells.
