In E6 chick embryos, hSF revealed a smaller tropism for nerves than hADSC. (A) In situ hybridization with Alu probes and Alcian blue counterstaining in cross-sections at anterior limb bud level. hSF were dispersed throughout the mesenchyme (dark blue nuclei), including the dermis (gray arrow). (B) In an adjacent section immunostained with HNK1, the majority of hSF (red outlines) were not adjacent to peripheral nerves. A,B, scale bar: 100 µm. d.r.g., dorsal root ganglion; m., mesonephron.
