【Abstract】 AIM: To investigate the effect of canstatin on cultured rabbit vascular smooth muscle cells(VSMC). METHODS: By means of cationic liposome mediated method, canstatin RNA was transferred into cultured VSMC. The proliferation quantity of VSMC were determined by the cell counting method and thymidine(-TdR) incorporation. RESULTS: Canstatin RNA could be effectively transferred into cultured primary rabbit aortic smooth muscle cells by the cationic liposome-Dosper and could markedly inhibit VSMC proliferation. CONCLUSION: Transfection of canstatin RNA could inhibit the growth of VSMC in vitro.更多还原
