Unformatted text preview: did he arrive at based on the results of these experiments? PSNs are required for the differentiation of small arterial blood vessels in the mouse limb skin. In addition to the differentiation markers that you have encountered in experiments described in figs 1 3, figure 4 describes the expression of two additional markers; BFABP (brain fatty acid binding protein) and alpha-SMA (alpha-smooth muscle actin). What cell types are specifically identified by these two markers? BFABP is expressed only by Schwann cells. Alpha-SMA is expressed only by smooth muscle cells (seen only around developing arteries, not veins)....
