Fig. 2. Detection of Mpl expression in the AGM and FL by in situ
hybridization. Transverse sections of E10.5
(A,B,D,H), E11.5
(C,E,I,J), E12.5 (F) and E16.5 (G)
mouse embryos were hybridized with Mpl antisense riboprobes. (A,B,C)
Mpl expression in the hematopoietic cells emerging from the ventral
wall of the aorta in the AGM region. (D,E,F,G) Mpl expression in the
liver at various times of development. (H,I,J) Mpl expression in the
yolk sac. The boxed areas are shown at high magnification to the right of each
panel.
