Abstract

Velvet antler (VA) is used in traditional Chinese medicine to treat a wide range of ailments including the enhancement of wound healing. A 3.2 kDa recombinant polypeptide of VA from sika deer was purified and compared to native polypeptides stimulation growth of NIH3T3 cells. Both stimulated growth in a dose-dependent manner (10-100 μg/ml). To study its wound healing properties, burn-wounded rats were topically administered with recombinant VA polypeptide or native polypeptide. Rats treated with 0.05 and 0.1% (w/w) polypeptides exhibited significant wound healing. As the yield of recombinant polypeptide was 40-fold higher than that of the native polypeptide, it may therefore be a useful biopharmaceutical.
