Abstract: OBJECTIVE: The aim of this study was to investigate growth and differentiation of neural stem cells (NSCs) on the phosphatase and tensin homology deleted on chromosome ten (PTEN)-inhibitor-adsorbed chitosan scaffold. METHODS: NSCs were divide into the chitosan group and the control groups, and performed CCK-8 test on 1(st), 3(rd) and 7(th) d to compare the proliferation between the 2 groups. The chitosan scaffold adsorbed PTEN inhibitor bpv (pic), and the empty scaffold was used as the control for co-culture of NSCs, immunofluorescence staining was performed on 7(th) d to detect the differentiation of NSCs on the scaffold. RESULTS: The results of CCK-8 test showed no significant difference in the absorbance between the 2 groups. Immunofluorescence staining showed that the NSCs numbers of the bpv scaffold group were more than the empty scaffold group, among which the anti-glial fibrillary acidic protein (GFAP) positive cells were less than the empty scaffold group, while the anti-β-Tubulin III positive cells were more than the empty scaffold group, the two groups both showed rare anti-receptor-interacting protein (RIP) positive cells. CONCLUSIONS: Chitosan scaffold exhibited good compatibility to NSCs, the PTEN-inhibitor-adsorbed chitosan scaffold could promote the migration of NSCs towards the scaffold and their differentiation towards neurons.
