Representative immunofluorescent images of the astrocytic and neuronal response. Tissue surrounding gelatin-coated needles with or without embedded MC-NPs at 3 days (two left columns) and 7 days (two right columns) post implantation. Images show astrocytes (GFAP) (a–d), neurons (NeuN) (e–h), cell nuclei (DAPI) (i–l), and merge (m–p). Scale bar = 100 μm
