Fig. 2. Developmental expression profiles of TAF7L, TBP and TAF7. (A) Double labelling immunodetection of TAF7L and TBP in developing male germ cells. TAF7L and TBP are detected in microdissected segments of seminiferous tubules from the stages shown in each panel. (B) Double labeling immunodetection of TAF7L and TAF7. Representative examples of cell types are indicated. ES, elongating spermatids; LS, leptotene spermatocytes; MDS, meiotic dividing spermatocytes; PS, pachytene spermatocytes; RS, haploid round spermatids; ZS, zygotene spermatocytes. Magnification, 40x.
