(A) Graphical representation of CRISPR-Cas9-mediated gene editing of the Actl7b locus using two guide RNAs (black arrowheads) targeting the intron-less Actl7b -coding sequence. 473 bp were deleted, causing a frameshift leading to a premature stop.

(C) Actl7b expression and ACTL7B immunolocalization during spermiogenesis based on literature ( ; ; ). ES, elongating spermatids; P, pachytene spermatocytes; RS, round spermatids; S, spermoatogonia; SP, spermatozoa.

Figure Lengend Snippet: Morphology of Actl7b -deficient seminiferous tubules. (A) Hematoxylin and Eosin staining of Bouin-fixed paraffin wax-embedded testis sections of Actl7b −/− mice. Immature apoptotic germ cells can be seen to be released into the lumen (green arrows). At late stage VIII, elongated spermatids with an abnormal morphology, which were not spermiated, were seen (green arrowheads) and round spermatids blocked in development with dark cytoplasm were found (orange arrows). Vacuolation of seminiferous tubules was detected (orange arrowheads). Scale bars: 50 µm. (B,C) Transmission electron micrographs of vesicles filled with degrading spermatids detected in Actl7b −/− seminiferous tubules. N, condensed nuclei; dN, degraded nucleus; G, granular material. Orange arrowheads indicate acrosomal structures; green arrowheads indicate flagellar cross-sections; green arrows indicate mitochondria. Scale bars: 5 µm in B; 2 µm in C. (D) Western blots on protein extractions from whole Actl7b +/+ , Actl7b +/− and Actl7b −/− testis. Anti-LC3 and anti-CSTB were used. α-Tubulin was used as a loading control.
