| Abstract: | The morphological development of the seminiferous epithelium in the pig at different ages ( Sus scrofa , Landrace breed)
In the Pig, Landrace breed, were observed, at different ages, among 15 to 210–220 days, the morphological patterns of the seminiferous epithelium that lines "cordonal" tubules at 15 to 30 days of postnatal and "luminal" tubules at 120 to 210–220 days of age. Although some morphological events of cellular differentiation were observed at 120 days, and the spermatogenesis process apparently could be observed at 180–190 days, really the overall characteristics of the cellular differentiation in the seminiferous epithelium, with the presence of luminal spermatozoa, were observed at 210–220 days of age. This last stage is considered as the puberal age. |
