We introduced improved primary mixed glial culture and different-attachment method to isolate and purify the OPCs, the cells were proliferated in serum-free medium, flow cytometry and immunohischemistry methods were employed to estimate the purity of cultured OPCs. Their abilities of differentiation and expression of trophic factors were identified by RT-PCR and immunostaining. Several methods including TUNEL and MTT were adopted to estimate the protective effects of conditioned culture medium from oligodendrocyte lineage cells on the primary cultured cerebellar granule neurons. Intravitreal transplant of OPCs, combined with retrograde fluorescent labeling the superior colliculus and intraorbital optic nerve transection, were used to investigate the protective effects of OPCs on the axotomized RGCs in vivo. Intravitreal transplantof OPCs or NSCs on the newborn rats, and retinal transplant of OPCs on the young rats were performed, to observe the myelin formation in the retina at different stages after cellular transplantation. Optic nerve transection was carried out on some rats with myelinated retinae, to study the influence of myelination on the injuried RGCs.

Estrogen deficiency can increase the mRNA expression of MMP-1、MMP-3 and IL-1β in OA synovia tissue. Estrogen could inhibit the mRNA expression of MMP-1、 MMP-3 and IL-1β in OA synovia tissue. Progestin could even decrease this expression. Estrogen could slightly increase the mRNA expression of TIMP-1. It is suggested that low dose of estrogen supplement play a protective effect on OA cartilage, and progestin could increase this protective effect.
