Spermatogenesis and spermiogenisis in the testes of local Iraqi breed cat (Felis catus)
The seminiferous epithelium of the testes of cat consists of two groups of cells; Spermatogenic cells and Sertoli cells. The interstitial areas are filled with Leydic cells, blood and lymph vessels, and connective tissue.

Retinoic Acid Receptors Control Spermatogonia Cell-Fate and Induce Expression of the SALL4A Transcription Factor. [PDF]
All-trans retinoic acid (ATRA) is instrumental to male germ cell differentiation, but its mechanism of action remains elusive. To address this question, we have analyzed the phenotypes of mice lacking, in spermatogonia, all rexinoid receptors (RXRA, RXRB

Doxorubicin and vincristine affect undifferentiated rat spermatogonia [PDF]
Anticancer drugs, such as alkylating agents, can affect male fertility by targeting the DNA of proliferative spermatogonial stem cells (SSC). Therefore, to reduce such side effects, other chemotherapeutics are used. However, less is known about their potential genotoxicity on SSC. Moreover, DNA repair mechanisms in SSC are poorly understood.

Spermatogonial stem cells (SSCs) possess a unique ability to recolonize the seminiferous tubules. Upon microinjection into the adluminal compartment of the seminiferous tubules, SSCs transmigrate through the blood-testis barrier (BTB) to the basal ...
