Fig. 1. Mpl expression in hematopoietic organs of control C57Bl6
embryos. Mpl expression was assessed by RT-PCR analysis in the
mouse fetal liver (A), AGM region (B), spleen and thymus
(C) from individual embryos. PCR of Actb (Actin) and
Mpl were performed in parallel, in order to normalize Mpl
signal after 35 cycles of amplification.
