Figure 1. Olfactory ensheathing cells culture, purification, and immunofluorescence staining. A: OECs cultured for 8 days, B: OECs cultured for 14 days C: cultured for 8 days, D: cultured for 14 days OECs with immuofluorescence staining. NGFR-p75 staining for OEC (red); fibronectin staining for ONF (green). The scale bar is 20 μm.
