Fig. 3. In vivo colocalisation of incorporated BrdU and KIN17 protein in adult testis. (A,D) BrdU staining appears green. (B,E) KIN17 staining appears red. (C,F) merged images where the colocalisation of KIN17 protein and BrdU appears yellow. (F) shows a magnification of the spermatogonia in merged images of the indicated area in D and E. Stages of the seminiferous epithelium are indicated with Roman numerals. Preleptotene spermatocytes: S, spermatogonia: Sg. Bars: A, B, C, D and E, 32 µm; F, 13 µm.
