[Research progress of bone marrow mesenchymal stem cells differentiation into nerve-like cells induced by traditional Chinese medicine].

Bone marrow mesenchymal stem cells (MSCs) have active abilities of self-replication and multidifferentiation. In recent years, a lot of studies have proved that MSCs can be induced and differentiated into nerve-like cells under certain conditions. Because of some advaced characteristics including sampling convenience, no immune rejection, high transfection rate and stable exogenous gene expression, MSCs will provide new way in treating disease of nervous system.

[Effects of Shibao Powder on promoting the expression of b-FGF and TGF-beta 1, in the repair of soft tissue injuries].

Objective: To study the effects of Shibao Powder on the expression of b-FGF and TGF-beta 1 in granulation tissues of rabbit models with soft tissue injuries, so as to explore mechanism of external Chinese drugs for repairing of soft tissues in molecular levels.

Methods: The rabbit models were established by classical method of full-thickness skin wounds. After 8% sodium sulfide was used and routine disinfection completed, intra-peritoneal anaesthesia was adopted.
