The mammalian seminiferous epithelium consists of a highly complex yet well-organized
cell population, with germ cells in mitosis and meiosis and postmeiotic cells undergoing …

The aim of this study was to evaluate the distribution of inhibin/activin alpha, beta (A) and
beta (B) subunits and follistatin in immature oocytes and in matured oocytes before and after …

Context Young boys treated with high-dose chemotherapy are often confronted with infertility
once they reach adulthood. Cryopreserving testicular tissue before chemotherapy and …

The proto-oncogene c-kit is encoded at the white-spotting locus and in the mouse mutations
at this locus affect the precursor cells of melanocytes, hematopoietic cells, and germ cells. c …

Identification and isolation of spermatogonial stem cells (SSCs) are a prerequisite for
culture, genetic manipulation, and/or transplantation research. In this study, we established …

The aim of this study was to develop a cryopreservation protocol for type A spermatogonia.
Testes from 5‐to 7‐month‐old calves were collected, and type A spermatogonia were …

The continuation of the spermatogenic process throughout life relies on a proper regulation
of self‐renewal and differentiation of the spermatogonial stem cells. These are single cells …

Background To isolate and characterization of human spermatogonial stem cells from stem
spermatogonium. Methods The disassociation of spermatogonial stem cells (SSCs) were …

Studies in rodents show that spermatogonial transplantation is an excellent new tool for
studying spermatogenesis and for preservation and dissemination of genetics. The aim of …

Introduction Presently the techniques for making transgenic animals are cumbersome,
required costly instruments and trained man-power. The ability of spermatogonial stem cells …
