高血压、动脉粥样硬化、肺动脉高压等疾病均以血管平滑肌细胞的异常增生和迁移为特征。为此 ,近几年来 ,血管平滑肌细胞的培养已经成为研究工作的基础。目前 ,仍然多采用贴块片[1 ] 。因其方便经济、技术难度低 ,但贴块片确有不足之处 ,如细胞容易出现“去分化”或“调整”现象 Hypertension, atherosclerosis, pulmonary hypertension and other diseases are characterized by abnormal proliferation and migration of vascular smooth muscle cells. To this end, in recent years, the culture of vascular smooth muscle cells has become the basis of research work. At present, the patch is still used more [1]. Because of its convenient economy, low technical difficulty, but patch does have shortcomings, such as cells prone to “de-differentiation” or “adjustment” phenomenon
