GDNF Enhances Therapeutic Efficiency of Neural Stem Cells-Based Therapy in Chronic Experimental Allergic Encephalomyelitis in Rat

Figure 1

The generation and characterization of the neurosphere in vitro. (a) Cultured neurospheres derived from cerebral tissue of newborn rats at culture of 7 d. (b) Immunocytochemical staining of nestin in neurospheres. (c) Neurospheres infected by GDNF recombinant adenovirus for 2 days showed green fluorescence under fluorescence microscope. (d) RT-PCR showed higher level of GDNF mRNA in the GDNF/NSCs than NSCs. (e) Quantitative analysis of the percentages of NSCs and GDNF/NSCs differentiated into each type of neural cells (mean ± SD, ). with NSCs group, . (f–k) Immunostaining showed, respectively, MAP2, GalC, and GFAP-positive cells from neurospheres. (f) MAP2⁺ cells from NSCs; (g) MAP2⁺ cells from GDNF/NSCs; (h) GalC⁺ cells from NSCs; (i) GalC⁺ cells from GDNF/NSCs; (j) GFAP⁺ cells from NSCs; (k) GFAP⁺ cells from GDNF/NSCs; (a–c) bar = 50 μm; (f–k) bar = 75 μm.
