Umbilical Cord-Derived Mesenchymal Stem Cells Improve Ornidazole-Induced Asthenozoospermia in Rats via Activation of the AKT/mTOR Pathway.

Mesenchymal stem cells (MSCs) have been highly confirmed for their critical role in the treatment of different diseases. This study focuses on the mechanism of umbilical cord-derived MSCs (UC-MSCs) in the treatment of ornidazole (ORN)-induced asthenozoospermia (AS) in rats via the AKT/mTOR pathway. An animal model of AS was established in ORN-induced rats, followed by treatment of UC-MSCs and rapamycin (autophagy activator) or MK-2206 (AKT inhibitor).

[Biological identification on sub-cultivation cells of Schistosoma japonicum adult worms in vitro].

Cultivation of cells from 30-day old Schistosoma japonicum (S.j) adult worms showed that the growth features of the cells were semi-floating and accumulative. The survival rate of the primary cells, passage cells prior to the 5th generation and recovered cells was all up to 90%.

[Identification of the source and types of cells of Schistosoma japonicum by histochemical staining].

Objective: To study the possibility on in vitro identifying the source or kinds of cells from Schistosoma japonicum (S.j).

Methods: The cells from digested tissues of 18 days old schistosomula were smeared on slides.
