Anti-VGLUT1 immuno-staining of (a) the control nerves and (b to g) all groups, 60 days after surgery. h Quantification of the integrated density of pixels in the experimental groups relative to control group (%). Statistically, the difference between N + F versus N + F + D + T and N + F + D versus N + F + D + T groups are meaningful with p < 0.05 and p < 0.01, respectively. Scale bar: 50 μm. N: neurorrhaphy, F: heterologous fibrin sealant, D: doxycycline, T: transgenic hESCs
