Fig. 3: Hippocampal cells cultured on Pt smooth film and Pt MA film on day 10.

a–f GFAP (a, b) and TUJ1 (d, e) immunostaining of Pt smooth film (a, d) and Pt MA film (b, e). GFAP (c, Pt smooth film, n = 36 images from six samples; Pt MA film, n = 51 images from nine samples) and TUJ1 immunoreactivity (f, Pt smooth film, n = 22 images from five samples; Pt MA film, n = 35 images from seven samples) were compared using two sample t-tests, shown as the means ± SEM (***p < 0.005). g–h SEM images of hippocampal neurons cultured on Pt smooth film (g) and Pt MA film (h); neurons and neurites are shown in pseudocolors
