Figure Lengend Snippet: NSCs produce neurotrophins and reduce micro- and macrogliosis in SOD1G93A mice. The amounts of ( A ) GDNF, ( B ) BDNF, ( C ) NT3 and ( D ) TGF-α secreted by the NSCs were determined by ELISA, which demonstrated a significant production of these neuroprotective substances with respect to fibroblasts. ( E ) Expression of GFAP (red) was reduced in the spinal cord of transplanted SOD1 mice. Nuclei are stained with DAPI (blue). Scale bar: 70 µm. NSC transplantation significantly reduced the presence of microglial cells ( F ) and astrocytes ( G ) in the spinal cord of intrathecally and systemically injected mice (data represent the mean ± SD, *significant, P < 0.001, ANOVA).

Article Snippet: On day 24, we added the growth factors BDNF, GDNF and insulin-like growth factor-1 (10 ng/ml each; PeproTech).
