OBJECTIVE To study the cytotoxicity of polyamide amine dendrimers (PAMAM)-hyaluronic acid(HA)as a non-viral gene delivery vector in vitro. METHODS PAMAM-HA was synthesized by our laboratory. Cytotoxicities of various polymers on HeLa cells,Bel-7402 cells and HepG2 cells were evaluated by MTT assay. Apoptotic rates were determined by flow cytometry. RESULTS The cytotoxicity of PAMAM-HA polymer increased with the concentration of polymer(50-800 mg · L-1),the time of action(24-72 h), the number of generations of PAMAM(G4,G5) and decrease in the molecular mass(3850,17 200)and the graft density(5%-25%)of HA. After incubation with PAMAM G4-HA3850-5%or PAMAM G5-HA3850-5%for 24 h,the apoptotic rate of hepatoma cells—Bel-7402 cells was 4.5%and 9.9%,respectively. After incubation with complexes of PAMAM G4-HA3850-5%/DNA or PAMAM G5-HA3850-5%/DNA for 24 h,the viability of HeLa cells was more than 80%,which was lower than that of PAMAM G4/DNA和PAMAM G5/DNA. CONCLUSION Cytotoxicity of PAMAM modified by HA of different grafting density and quantity can be reduced ,suggesting the PAMAM is a promising non-viral gene vector.

Objective:To investigate the expression pattern of Mtsl/S100A4 in mouse spinal cord;to investigate the effects of Mtsl/S100A4 on glial cell responses.Method:The study was carried out on Mtsl/S100A4 wild type and knock-out mice.The degenerative spinal cord model was established by dorsal root or sciatic nerve injury.The de-myelinated spinal cord model was established by ethidium bromide injections.Then the expressions of S100A4,GFA P,NG2 and Mael were measured.Result:The expressions of Mtsl/S100A4 in mice spinal cord were similar to that in rats.In WT mice this protein expressed in a thin layer of fiber bundles in the tract of Lissauer,and in white matter astrocytes.There was intracellular up-regulation of Mtsl/S100A4 in white matter astrocytes of WT mice after dorsal root or sciatic nerve injury,with no difference in glial cell response between WT and KO mice.However,7 days after ethidium bromide injection,in WT mice,the astroglial reaction was restricted on operated side,where a distinct glial scar had formed.While in KO mice,no distinct glial scar formed in demyelinated area.Conclusion:Mtsl/S100A4 expression in mouse spinal cord is similar to the pattern as in rats;intracellular Mtsl/ S100A4 up-regulation does not affect glial responses in degenerative spinal cord;the presence of extracellular Mtsl/ S100A4,which entered the spinal cord after ethidium bromide induced demyelination,markedly affects the glial cell responses in demyelinative spinal cord,including glial scar formation.

AIM:To study whether three kinds of rabbit corneal cells can grow well on fibrin glue (FG) constructed in vitro, and investigate the feasibility of FG for the scaffold of cell sheet engineering. METHODS: Three kinds of corneal cells were seeded on FG which was produced in vivo. Cell growth on FG was examined as follows: (1) by inverted microscope; (2) histologically by hematoxylin and eosin; (3) by scanning electron microscopy. RESULTS: Fibrin glue prepared was smooth and transparent. With cell growth, FG degradated partly, then obtained cell sheet engineering only with a small amount of FG. Corneal cells generated well on the fibrin glue in vitro and maintained the physiological state of cells. Corneal epithelial cells formed unilaminar and stratified layers and cellular joins. Corneal endothelial cells formed round or polygon, the same size cells and lined up tightly. Corneal stroma cells formed triangle and arborization, cell-cell junction was obvious, and formed network link. CONCLUSION: Fibrin glue is well compatible with three kinds of corneal cells, which can construct tissue engineered cell sheet with fibrin glue, so as to reconstruct ocular surface.
