Fig. 8. Cultured cells from E17 rat spinal cord double-labelled for Fgfr3 and Gfap. Cells were hybridised in situ with a ³⁵S-labelled RNA probe for Fgfr3, then immunolabelled for Gfap followed by autoradiography (see Materials and Methods). The Fgfr3 signal (black silver grains) is present over most Gfap-positive cells (brown DAB reaction product; arrows) (also see Table 1). Scale bar: 10 µm. Arrohead indicates an Fgfr3-positive, Gfap-negative cell.
