Fig. 1From: Shift in the function of netrin-1 from axon outgrowth to axon branching in developing cerebral cortical neuronsExpression of DCC protein in mouse primary cortical axons. Neurons prepared from E14 (a) and E16 (b) mice were fixed after 5 DIV, permeabilized, and then immunostained for DCC. DIC images of the same fields are also presented below (c, d).
