Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.

The results of study show:1. White pulp and red pulp in parenchyma of spleen of embryo can be obviously discerned after 18 days. Periarterial lymphoid sheath and ellipsoid periarterial lymphoid sheath also can be obviously discerned in spleen of 4 days chicken. T, B lymphocytes in appendix basement of embryo emerge after 20 days. It is the initial shape of cecal tonsil. Crypt structure of conjunction of esophago and stomachus glandularis form obviously at 4 days. It is the initial shape of esophago tonsil. The germinal center firstly emerges in these three organs at 14 days. With the increase of day age, the characteristic structure peripheral immune organs gradually develop mature. Spleen achieve mature at 21 days and cecal tonsil at 35 days.2. IgM~+ and IgA~+ cells in spleen of embryo emerge at 15 days. IgG~+ cell, CD3~+ and CD8~+T lymphocytes of embryo emerge at 20 days. CD3~+, CD8~+ and IgM~+ cells in cecal tonsil of embryo emerge at 20 days. However CD4~+, IgG~+ and IgA~+ cells all emerge in 1 day age chicken out of crust. CD3~+, CD4~+, CD8~+, IgM~+ and IgG~+ cells in esophago tonsil of embryo all emerge at 20 days. However IgA~+ cells emerge in 1 day age chicken out of crust.3. The amount of T, B lymphocytes in peripheral immune organs increase follow with the increase of day age, and hold an upgrade tendency. The amount of T, B lymphocytes in spleen achieved stabilization at 21 days, and in tonsil of esophago and appendix at 35 days.

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.
