Configuration and distribution of bovine spermatogonia
Cell and Tissue Research, 1995The configuration and distribution of bovine spermatogonia, preleptotene primary spermatocytes and Sertoli cells in the basal seminiferous tubular compartment have been studied by means of whole-mount preparations, immunohistochemistry and quantitative morphology. Three types of spermatogonia (Sg) can be identified.

1. A description is given of form and components of the three types of spermatogonia: type A, I, and B. 2. The distribution of the stem cells (=type A-spermatogonia at the beginning of the cycle, i.e. after the release of the mature sperms) is rather irregular. 3. The mean number of stem cells per cross section of a tubule is

Isolation and transplantation of spermatogonia in sheep
Theriogenology, 2006Studies in rodents show that spermatogonial transplantation is an excellent new tool for studying spermatogenesis and for preservation and dissemination of genetics. The aim of this study was to adapt the technique to rams. Two issues were addressed: purification of stem cell spermatogonia, and efficient injection of donor spermatogonia into the ...

Radiation Research, 1992
In the CBA mouse the radiosensitivity of the undifferentiated spermatogonia that are committed to differentiate was determined by counting their more developed descendants 10 days after graded doses of X rays. Decreasing D0 values were found when these differentiating spermatogonia were derived from undifferentiated spermatogonia that were located in ...

Xenogeneic transplantation of human spermatogonia
Zygote, 2000In the last 3 years, several studies have shown that xenogeneic transplantation of rodent spermatogonia is feasible. The treatment of infertile patients with spermatogenic arrest using the injection of immature germ cells has yielded only poor results.

The Anatomical Record, 1987
AbstractThe topographical arrangement of the clones of Asingle, Apaired, and Aaligned (As, Apr, and Aal) spermatogonia on the basement membrane of seminiferous tubules of the Chinese hamster was studied. It was found that at least some of these clones are not distributed at random as clones of similar cell number were often seen in clusters. Areas were

Perspectives: Approaches for Studying Livestock Spermatogonia
2023At present, the knowledge base on characteristics and biology of spermatogonia in livestock is limited in comparison to rodents, yet the importance of studying these cells for comparative species analysis and enhancing reproductive capacity in food animals is high. Previous studies have established that although many core attributes of organ physiology
