The histone variants H2AX, H2AZ, and H3.3 are predominantly present in TGC chromatin. (a,b) Protein levels of the H2A variants H2AX, H2AZ (a), and canonical H3 H3.1/3.2, and the H3 variant H3.3 (b) in TSCs and dTSCs. Upper panel shows western blotting results for H2AX, H2AZ, pan-H2A (a), H3.1/3.2, H3.3 and pan-H3 (b). Western blotting was performed using total histones equivalent to 0.5 μg of genomic DNA. Bottom panel shows H2AX, H2AZ, H3.1/3.2, and H3.3 levels in dTSCs, which were normalized to the pan-H2A (a) or pan-H3 level (b) (Fig. S1). The values were expressed as a ratio relative to the maximum average. The mean ± standard deviation (S.D.) of three independent experiments are shown. *P < 0.05 versus TSC (Student’s t-test). (c) Immunofluorescence staining of H2AX, H2AZ, H3.1/3.2, and H3.3 in TSCs and dTSCs at day 4, 6, and 8 of differentiation. Bars = 10 μm.
