Fig. 5. Fgfr3-positive cells are unaffected in Pdgfa null spinal
cords. Consecutive sections of newborn wild-type or Pdgfa knockout
mouse cervical spinal cords were hybridised in situ with probes to
Fgfr3 (A,B) or Pdgfra (C,D). The number of
Pdgfra+ OLPs is strongly reduced in the Pdgf-A
knockout (compare C with D) but neither the number nor the distribution of
Fgfr3+ cells is changed noticeably (A,B). Again, we
conclude that the Fgfr3+ cells and
Pdgfra+ OLPs are different cells.
