Proliferation evaluation of SCs co-cultured with living nerve microtissues or PRP supernatant. A SCs exposed to various groups during 1, 3, 5, 7 days of co-culture. SCs in the SCs + Micro-T + PRP group had faster proliferation, better spread and became more enlarged in shape than other groups from the third day of co-culture. The SCs count results were shown in (B). C CCK-8 colorimetric assay was performed to evaluate the effect of different groups on the proliferation of SCs (^*P < 0.05, ^**P < 0.01, n.s. P > 0.05).
