Figure S1. The relative viability of hfNSCs in each group after 2 days of culture under self-renewal conditions, which was evaluated by MTT assay (n = 3, *p < 0.05 and **p < 0.01 versus No ferritin group). The viability of each group was normalized to that of the No ferritin group. Figure S2. The relative proliferation of hfNSCs in each group after 2 and 5 days of culture under self-renewal conditions, which was evaluated by MTT assay (n = 3, **p < 0.01 versus No ferritin group). The proliferation of each group at day 5 was normalized to that of each corresponding group at day 2. Figure S3. Immunofluorescence staining of primary hippocampal neurons for Tuj1 (green) and NeuN (red). Cell nuclei were counterstained with DAPI. Scale bar = 200 μm. (DOCX 1587 kb
