Schwann cells-laden conductive PGSAP-H films inducing PC12 cells differentiation. (A) Schematic diagram depicting PC12 cells differentiation and neurite extension when culture in medium suspension from Schwann cells (RSC96) on conductive films. (B) Quantitative analysis of neurite length of PC12 cells supplemented with the normal medium (NM) group, TCP group, PGS-H group, PGSAP-H group, TCP + NGF group, and NM + NGF group. (d) Frequency of neurite length distribution of PC12 cells of each group. *P < 0.05. Reproduced from Ref. [77] with permission of Elsevier.
