Summary of morphological, self-renewal and vasculogenic properties of cardiac progenitor cell clones.

Morphology was assessed by light microscopy and immunocytology. Last passage number: maximum number of passages to date. Vasculogenic index: length x number of tubes formed per high power field in Matrigel at 5 hours. SDF-1 levels were determined by ELISA (see Methods).

采用光学显微镜与免疫细胞学技术对样本形态学特征进行评估。末次传代次数：截至当前的最大传代代数。血管生成指数：5小时时于基质胶（Matrigel）中每高倍视野下形成的血管管状物长度与数量的乘积。基质细胞衍生因子-1（SDF-1）水平通过酶联免疫吸附测定（ELISA）确定，详见方法部分。
