Enhancement of self-renewal of hfNSCs by ferritin incorporation. a Microscopic observation of hfNSCs during culture for self-renewal and expansion with or without ferritin treatment. Scale bar = 200 μm. b qPCR analysis for evaluating gene expression of neuronal progenitor and stemness markers (Nestin, OCT4, and Nanog) in the generated neurospheres after 6 days of culture (n = 3, *p < 0.05 and **p < 0.01 versus No ferritin group)
