... that is sufficient to direct expression throughout the lateral mesoderm, beginning at 7.5 days of mouse embryonic development. The activity of this enhancer is initially broad but eventually becomes restricted to the mesenchyme surrounding the liver. We demonstrate that the function of this enhancer in transgenic...

... cell mass (ICM) in the posterior midline of the embryo 1 day after fertilisation. These cells originate from the posterior lateral mesoderm(PLM) of the post-gastrula embryo ( Zhong et al., 2001 ) ( Fig. 1D ). Here, overlapping expression patterns of blood and endothelial genes suggest the existence...

... as in-situ hybridization for the expression of two new hemopoietic marker genes, draculin and leucocyte-specific plastin , we show that macrophages appear in the embryo at least as early as erythroid cells, but originate from ventro-lateral mesoderm situated at the other end of the embryo, just anterior...

... in nephric duct progenitors, nephric duct formation and the initiation of nephrogenesis. Thus, BMP-4 signaling can substitute for the surface ectoderm in supporting nephric duct morphogenesis. Collectively, these data suggest that inductive interactions between the surface ectoderm, lateral mesoderm...
