Figure Lengend Snippet: Morphological characterization of Ankrd31 –/– testes. (A) Comparative size analysis between WT and Ankrd31 –/– testes. Testis weight (mg) analysis was carried out on WT and Ankrd31 –/– testes ( n = 20). Data are reported as mean value ± S.E.M. (B,C) Defective spermatogenesis was observed by H&E staining of WT and Ankrd31 –/– Bouin’s fixed seminiferous tubule sections (7 μm) collected from 8-week-old testes. SPG, spermatogonia; SPC, spermatocytes; rSPT, round spermatids; eSPT, elongated spermatids (black-arrowheads). (D,E) Cells in metaphase are indicated by white arrowheads. (F) Quantification of seminiferous tubules containing spermatocytes in metaphase in WT and Ankrd31 –/– testes ( n = 10 for each genotype). The number of total tubules counted in five different animals for each genotype corresponded to n = 650. Data are expressed as percentage (%) of tubules containing cells in metaphase and reported as mean ± SEM, ** p < 0.01. (G,H) Classification of germ cells in respect to chromatin structure marked with DAPI staining in WT and Ankrd31 –/– testicular sections (7 μm). The elongated spermatids not correctly oriented toward seminiferous lumen are indicated by white arrowheads. (B–H) Scale bar corresponds to 50 μm; (D,E) scale bar corresponds to 25 μm.
