...ound associated with the spermatogonia type B, pachytene spermatocytes and Sertoli cells. The results from this study show that there are basic similarities in the Leydig cells of the vervet compared to other mammals, humans and nonhuman primates, however, there also seem to be species differences among the mammalian group. The association of these cells with developing cells, and Sertoli cells was established. However, the association of Leydig cells with spe...

...e first time. Results of spermatogonial metaphases showed that the chromosome number and the karyotype formula of the species was 2n♂=35 (X1X2X30) which is the first record for the family Hersiliidae. Both autosomes and sex chromosomes were acrocentric. The lengths of the chromosomes indicated no significant difference between autosomal pairs, however, X3 was the smallest chromosome but X1 and X...

...d in the reproduction of spermatogonial stem cells (SSCs). To date, commercialized murine and human GDNF have typically been used for the in vitro culture of SSCs from domestic animals. However, whether endogenous GDNF is superior to xenogenic GDNF in SSC culture in vitro remains unclear. To answer this question, the buffalo GDNF gene was cloned and integrated into the PiggyBac eukaryotic expression vector, which was stably expressed in Sertoli c...
