Immunostaining and quantification of AMH⁺ or SOX9⁺ cells in porcine testis sections. A AMH and SOX9 immunostaining of porcine testis sections at each age. Bar = 10 μm. B The numbers of SOX9⁺ cells per cross-section of seminiferous cords/tubules in porcine testes at each age. Data are presented as the mean ± SEM of three littermates, with 50 round cord/tubule cross-sections analyzed per individual. Different letters indicate significant differences between groups (P < 0.05)
