Localization of SPATC1L in germ cells during spermatogenesis. Isolated spermatogenic cells were immunostained for SPATC1L (red) and γ-tubulin (green). γ-Tubulin was used as a centrosome marker, and cells were counterstained with the nuclear dye Hoechst 33342 (blue). Fluorescence images of individual staining are shown at the top and merged images are shown in the middle. Insets are magnified iamges. Sc, spermatocyte; RS, round spermatid; ES, elongating spermatid; TS, testicular sperm; MS, epididymal mature sperm; BF, overlay with bright field image.
