Inhibitory Effect of Tetrandrine on the Proliferation of Human Dermal Fibroblasts Derived from Hypertrophic Scars

Tetrandrine can inhibit the proliferation and collagen synthesis of fibroblasts in lung and liver tissue confirmed by a series of clinical research. In this chapter, we investigated the effect of Tetrandrine on the proliferation of human dermal fibroblasts derived from hypertrophic scars. The dermal fibroblasts were isolated from human hypertrophic scar tissues and cultured in vitro. Tetrandrine with different concentration were added to culture medium respectively. The proliferative activities were determined. The result show that when the concentration of added Tetrandrine increased from 5μg/ml to 80μg/ml, the proliferative activities of cultured dermal fibroblasts were decreased gradually in dose-dependent manner. It conclusions that Tetrandrine can obviously inhibit the proliferation of human dermal fibroblasts derived from hypertrophic scars.
