Radiosensitivity of testicular cells in the fetal mouse.

The effects of prenatal X irradiation on postnatal development of the CBA/P mouse testis was studied. At days 14, 15 and 18 post coitus pregnant female mice were exposed to single doses of X rays ranging from 0.25-1.

Radiosensitivity of testicular cells in the prepubertal mouse.

The effects of total-body X irradiation on the prepubertal testis of the CBA/P mouse have been studied. At either day 14 or day 29 post partum male mice were exposed to single doses of X rays ranging from 1.5-6.

Postnatal development of testicular cell populations in mice.

The postnatal development of body and testis weight and the size of the testicular cell populations were studied in CBA mice up to day 52 post partum. The body weight increased from 1.3 g at day 1 to 22.

Proliferative activity of gonocytes, Sertoli cells and interstitial cells during testicular development in mice.

Developing mouse testis was studied from Day 14 post coitum (p.c.) until Day 35 post partum (p.

The estimation of damage to testicular cell lineages.

Assuming that spermatogonial multiplication in primates will not be fundamentally different from that in non-primates it can be deduced that Ap and Ad spermatogonia in primates are analogous to the undifferentiated spermatogonia in non-primates. Ap and Ad spermatogonia consist of single, pairs and chains of cells, among which the single cells likely are the stem cells. The single Ap are the active stem cells while the single Ad only become active after cell loss.
