摘要：

In situ hybridization (ISH) analysis of the murine melanosomal gene, Pmel17, demonstrated robust expression in the presumptive retinal pigmented epithelium (RPE) starting at E9.5, and in neural crest-derived melanoblasts starting at E10.5. Pmel17 expression is not detectable in;embryos mutated for Microphthalmia-associated transcription factor (Mitf), demonstrating transcriptional dependence of Pmel17 on Mitf in the RPE. Pmel17 expression in dorsal regions precedes dopachrome tautomerase (Dct) ISH expression, suggesting Pmel17 identifies melanoblasts at an earlier developmental stage. Dorsally localized Pmel17-positive cells at the forebrain/midbrain and midbrain/hindbrain boundaries at E10.5 reveal migratory pathways for cranial melanoblasts that have not been previously described in mouse using Dct expression.
