Figure 7.

Limited coexpression of contactin2 with sidekicks or dscams. a, b, Sections of E16 retina were stained with anti-Cntn2 plus antibodies to either Sdk1 (a) or Sdk2 (b). Sublaminar localization of Cntn2 overlaps with those of both Sdks. c–f, Expression of sdk1, sdk2, dscam, and dscamL was compared with that of cntn2 by two-color in situ hybridization of E15 retina. Few if any cntn2-positive cells expressed sdk2, dscam, or dscamL, but ∼50% coexpressed sdk1 (arrowheads in c). Scale bar: 10 μm for a, b; 5 μm for c–f.
