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

Journal of Developmental and Physical Disabilities, 1981 A comparison has been made between gonocytes and adult type undifferentiated spermatogonia in the mouse. The following morphological resemblances were noted: 1.

Strain Differences in the Radiosensitivity of Mouse Spermatogonia
International Journal of Radiation Biology and Related Studies in Physics, Chemistry, and Medicine, 1985 The radiosensitivity of spermatogonia was found to be greater by up to a factor of 2 in C3H mice than in B6D2F1 mice, whether assessed for the highly sensitive spermatogonia (types A2 to In) or the much more resistant clonogenic spermatogonia which ...

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 ...

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.

AbstractIn this study the yield of the proliferation of the differentiating spermatogonia into spermatocytes was determined in five Chinese hamsters. Large differences of up to a factor 2 were found between the numbers of A1 spermatogonia in the various animals.
