Figure 5. FN is required for proliferation of cells in splanchnic mesoderm.
A–B. E8.75 control (A) and mutant (B) embryos were stained with anti-pHH3 antibody (green) and DAPI (blue). Representative sections are shown. Splanchnic mesoderm is underlined by the dotted lines and shown enlarged in A′–B′. C. Quantification of the fraction of pHH3+ labeled cells in splanchnic mesoderm. 4–5 sections from each embryo were analyzed, total of 413 control and 537 mutant nuclei were counted per genotype.
