Residual melanocyte marker expression in sox10, mitfa, and sox10;mitfa mutants.
A–AB) Expression of dct, tyr, silva and tyrp1b in wild-type (WT), sox10t3, mitfaw2 and sox10t3; mitfaw2 mutants is shown at 24 and 36 hpf as indicated. Insets in each panel show enlargement of area of dorsal posterior trunk. Note the pronounced derepression of silva and dct, mild derepression of tyr, and minimal residual expression of tyrp1. Note that all in situs were over-developed in order to detect low level expression.
