Figure 3: Ezh2 is not required for normal melanocyte homeostasis.

(a,b) Mouse genotypes (a) and strategy (b) used to analyze the effect of conditional Ezh2 ablation in the melanocytic lineage of adult wild type mice. (c) Macroscopic pictures and H&E staining on trunk skin sections of control and cKO mice at 5 months and 1 year post conditional Ezh2 ablation. (d) Immunofluorescent staining on trunk skin sections of wt mice for β-Gal to quantify recombination efficiencies (representative fields not shown). (e) Immunofluorescent staining on trunk skin sections of wt mice for Sox10 (control) or β-Gal (cKO) and H3K27me3 to quantify H3K27me3 depletion. White arrowhead, Sox10-positive cell considered H3K27me3 positive; white open arrowhead, β-Gal-positive cell considered H3K27me3 negative. H&E, haematoxylin and eosin; HF, hair follicle. Data are represented as mean±s.e.m. of n=3. P values calculated with unpaired Student’s t-test. Scale bars, 50 μm.
