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.

MAIN OUTCOME MEASURES: Morphological changes in primary cultured and subcultured mouse BMSCs were measured. BMSC surface antigen of the second passage of mice (CD105, CD44, CD25, CD34) were determined using flow cytometry. The modified method was assessed to harvest the purity of stem cells. Activity of mouse BMSCs was identified using adipogenic and osteoplastic differentiation. The strength of fluorescent cells following multiple passage was observed.

The mature egg cell was an inactive cell with only a few polysomes. At the early zygote stage, a large number of ribosomal precursors were produced by the nucleolus, and many polysomes appeared in the cytoplasm, which suggests a high level of metabolism. Zygote at the dormancy stage had a small nucleolus and marked decrease in ribosomes, as shown by a few polysomes, which suggests decreased metabolism. Zygotes in the prophase of mitosis and two-celled proembryo became active again in metabolism, for a prominent nucleolus, high density of ribosomes and increased number of polysomes in the cytoplasm.

The injured gill cells had a different ultrastructure, with endoplasmic reticulum dilated and vesiculated, mitochondrial cristaes partially disintegrated, gill fibre cuticles denatured and dropped. The ultrastructural damages to hepatopancreatic cells were characterized by the decrease of microvilli, swelling and breaking up of mitochondria, expansion of endoplasmic reticulum, disruption and vacuolization of nucleus, tumefaction of nuclear membrane and increase of lipid droplets. As for the toxicological changes of myocardial cells, the mitochondria were swelling, having a lot of vacuolus and disintegrating, while the myofibrils were irregular with endoplasmic reticulum dissolved.

In order to elucidate the regulation mechanism of RU5 region to BFV gene expression, BFV3026 provirus DNA was used to construct the plasmids containing different deletion of R region, which were cotransfected with luc report gene locatied behind the IP promoter to BL12 cells, and luciferase activities was assayed, confirming that U5 region could repress the initiation function of LTR as well as IP. The BFV structure genes with different deletion of R region were cloned closely behind to heterogenous CMV promoter, then transfected to 293T cells, RT activity was performed, testifying the R region was required for BFV pol gene expression, and also the function domain was identified within the 100n.t. sequence at the 5′end.
