PDGFRA overexpression causes hyperplasia of OPCs and Schwann cells (a-c) Representative confocal images of the spinal cords of mCherry control (n=3), wild-type PDGFRA (n=3), and mutant PDGFRA (n=3) transgenic 6 dpf larvae in the nf1a+/+; nf1b-/-; p53m/m background. Both (b) wild-type PDGFRA and (c) mutant PDGFRA transgenic larvae demonstrate increased numbers of sox10:mCherry-positive oligodendrocyte progenitor cells (OPCs) as compared to (a) mCherry control larvae in the nf1a+/+;nf1b-/- ; p53 m/m background. (d) Quantification of the sox10:mCherry-positive OPC number within a 100 μm region of the thoracic spinal cord.
