    Abstract:
    This study evaluated the proliferative effects of chishao on RSC96, Schwann cells. A dose-dependent proliferative effect of chishao was obtained by methylthiazol tetrazolium (MTT), proliferating cell nuclear antigen (PCNA) Western blotting, and wound healing assays in Schwann cells administered with chishao (0-500 mg/ml), except at 500 mg/ml concentration. The chishao-treated cells also showed a dose-dependent activated fibroblast growth factor-2 (FGF-2) signaling with increased urokinase plasminogen activator (uPA) and decreased plasminogen activator inhibitor-1 (PAI-1), enhanced proliferative proteins, extracellular signal regulated kinase (ERK) and c-Jun N-terminal kinase (JNK)-signaling. Using mitogen-actvated protein kinase (MAPK)-signaling chemical inhibitors, U0126, SB203580, and SP600125, the proliferative effects of chishao on RSC cells were identified to be ERK- and JNK- signaling dependent. Based on the results, applying appropriate doses of chishao to Schwann cells would be a potential approach for enhancing neuron regeneration.
