Annual Cycle of the Seminiferous Epithelium of Myotis macrodactylus

Seminiferous Epithelium Cycle in Bombina orientalis

The purpose of the present study was to examine the seminiferous epithelium cycle of Bombina orientalis using a light microscope. The cycle was divided into a total of 10 stages, according to the morphological characteristics of the cells. The spermatogenetic cells included primary spermatogonia, secondary spermatogonia, primary spermatocytes, secondary spermatocytes, spermatid and sperm. At st...

Lectin Histochemistry Assessment of Seminiferous Epithelium Glycoconjugates in Mouse

Purpose: Plasma membrane glycoconjugates are important determinantsof differentiation and iteraction during spermtogenesis. Which entails miotic and meiosis proliferation, alternation in cell shape and so on. Hihg rates of them synthetized and present in acrosomes. With attention to such importancy, the present study has was designed to analyze glycoconjugates with special terminal sugar residu...

To Study the Changes of the Seminiferous Epithelium After Ga.Ai.As Laser Radiation (830Nm)

Purpose: The purpose of this study was to investigate the immediate effects of low power laser radiation (Ga-Al-As; 830nm) on the seminiferous epithelium of Sprague-Dawley rats. Materials and Methods: Male Sprague-Dawley rats were randomly divided into three groups (two experimental groups and the sham). The left testes of the animals were shaved, washed and marked at inferior pole. Then, they...

Localization of protamine 1 mRNA in different stages of the cycle of the rat seminiferous epithelium

A mouse protamine 1 cDNA probe was used to study P1 protamine gene expression during the cycle of the seminiferous epithelium in the rat. In situ hybridization experiments showed that transcription of the P1 protamine mRNA starts in the middle of step 7 of spermiogenesis during substage VIIc. The mRNA levels stay high in steps 7-14 spermatids but decrease during steps 15-16 and are virtually un...
