The ferroptosis of sertoli cells inducing blood-testis barrier damage is produced by oxidative stress in cryptorchidism.

Oxidative Stress (OS) is the main cause of damage to the Blood-Testis Barrier (BTB) in cryptorchidism, which seriously endangers male reproductive health. It is well known that the OS induced ferroptosis is an important cause of dysfunction in the body. However, it is still unknown whether BTB damage in cryptorchidism leads to ferroptosis of Sertoli cells.

Analysis of Histochemical Characteristics of Submandibular Gland of the Bactrian Camel.

The ultrastructure of submandibular gland (SMG) of Bactrian camels was observed by a transmission electron microscope. Routine HE staining, special staining combined with immunohistochemistry, and immunofluorescence techniques were used to study the histochemical characteristics of the submandibular gland and the localisation and distribution characteristics of epidermal growth factor (EGF) and epidermal growth factor receptor (EGFR). HE results showed that the submandibular gland of Bactrian camels was composed of mixed serous and mucinous acini glands.

Morphological characteristics and distribution identification of telocytes in Tibetan sheep testis and epididymis.

Telocytes (TCs) are a type of stromal cell discovered in the various organs of different animals and have many potential functions, including angiogenesis, signalling, and substance transport. However, the TCs have not been detected in the testis or epididymis of Tibetan sheep. This study investigated the position, characteristics, and distribution of TCs in the testis and epididymis of Tibetan sheep using transmission electron microscopy (TEM), toluidine blue staining, immunohistochemistry, and double immunofluorescence to elucidate their possible functions.
