Studies of hCG binding and endocytosis in rat ovary by ultrastructural immunocytochemistry

Abstract: Localization of hCG binding sites and the process of endocytosis in pseudopregnant rat ovaries were investigated by indirect electron-microscopic immunocytochemistry. Immature female rats were treated with pregnant-mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG) to induce ovarian luteinization. Eight days after priming with PMSG-hCG and 1-6 h before sacrifice the animals were given another injection of hCG to bind the receptors. Receptor sites to hCG localized by reaction product were pre… Show more

“…There have been several studies of the fate of hCG in target cells using either biochemical (5,6,14,15,45) or morphological (1,2,24,28,38) methods. However, no direct study of the LH receptor has been performed, at the electron microscopic level, probably due to the lack of specific antibodies.…”

“…The available information on in vitro propagation of Gymnocalycium is scarce and limited. Therefore, although relevant information exists for various species [42][43][44][45][46][47][48][49][50], more comprehensive research is needed to develop efficient and reproducible protocols for in vitro propagation. Additionally, these protocols should be feasible to implement and enhance performance in the ornamental plant industry.…”
