Schwann cell response on polypyrrole substrates upon electrical stimulation

Immunoflourescent staining (S-100 (red) + Dapi (blue)) of Schwann cells cultured on PPy films coated with Laminin then electrically stimulated (0.5 V, 2 h) after 2.5 h of incubation and fixed and immunostained 5.5 h post electrical stimulation (total incubation time 10 h). Scale bar = 200 μm.20
