对齐心肌组织的产生是一个关键的要求,适应干细胞生物学的最新进展,临床上有用的目的。在这里,我们描述了一个微接触印刷方法的精确控制细胞的形状和功能。使用高度纯化群体中的胚胎干细胞源性心肌祖细胞,然后产生各向异性功能的心肌组织。

以下实验的目的是通过微接触打印生成对齐的功能性心肌组织。这是通过首先将纤连蛋白微接触打印到聚二甲基硅氧烷基材上来实现的。作为第二步,双重转基因。

胚胎干细胞系在体外分化并通过荧光激活细胞分选进行分离,从而获得高度纯化的强心源性祖细胞群。接下来,将分离的心脏祖细胞接种到微专利 PDMS 底物上,使其恶性并呈心肌细胞状。获得的结果表明,基于事实和免疫荧光分析,心脏祖细胞的成功分离和各向同性生长。
