...ssociated 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 spermatog...

...t 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 X2

...he 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 cells, ...

The present findings reveal that during non-pubertal stage; continuous administration of kisspeptin may suppress hypothalamic-pituitary-gonadal axis and spermatogenesis.

...font-size: small;">Spermatogonial stem cells (SSCs), a class of primitive germ cells located on the basement of the seminiferous tubules of the testes, are the only kind of adult stem cells that can pass their genetic material to offspring and are also capable of proliferation and differentiation, ensuring the efficiency of passing transgenes from parents to subsequent generations. In this research, to understand the growth characteristics of buffalo SSCs i...

After quercetin administration, they showed an improvement in the previous biochemical parameters. Seminiferous tubule diameters were 105.2 ± 2.1 µm and their epithelium heights were 26 ± 2.1 µm. Remarkably, spermatogonia, spermatocytes, spermatids and sertoli were positively reacted with PC...

In past many of its sibling species were misidentified on morphological examination. However, DNA-based species assignments has now made it possible to overcome this barrier. In this study we present CO1 gene data set on the 6 species of Chrotogonus i.e. Chrotogonus (Chro
