Histological characterization of the polymer optical fibers (POFs) in vivo. A Representative examples of GFAP (red) and NeuN (green) immunostaining of the conventional silica optical fibers (SOFs) and POFs at 4 weeks after implantation. B, C Quantitative comparisons of GFAP (B) and NeuN (C) immunoreactivity between the SOFs and POFs (n = 8 in each group, mean ± standard deviation). Comparisons were performed using intensity profiles as a function of distance from the implant interface (shaded area: p < 0.005, t test)
