Sexually dimorphic expression of RPL5b and RPL24 in tilapia ovary and testis by immunohistochemistry. Samples were taken at 120 dah. Signals of RPL5b were observed mainly in the cytoplasm of oocytes in the ovary (A), while weak signals were detected in the spermatocytes in the testis (B). In contrast, very weak signals of RPL24 were observed in the cytoplasm of oocytes in the ovary (C), while strong signals were detected ubiquitously in different spermatogenic cells (D). Black arrows indicate positive signals. Scale bar, A and C, 10 μm; B and D, 16 μm.
