Fig 1: Immunofluorescence double staining of NOM cells cultured for 21 days in 2D stationary culture, prior to their seeding in the magnetic fibrin scaffolds. (A1) S100B (glia marker in red); (A2) NF (neuronal marker in green); (A3) merge of S100B and NF. (B1) Nestin (neuronal precursor marker in red); (B2) ß3Tub (neuronal marker in green); (B3) merge of nestin and ß3Tub. The nuclei of the cells were dyed in blue with DAPI.Abbreviations: NOM, nasal olfactory mucosa; 2D, two-dimensional; S100B, 100% soluble calcium-binding protein B; NF, neurofilament; ß3Tub, beta III tubulin; DAPI, 4',6-diamindo-2-phenylindole.
