一种体细胞类型向另一种体细胞类型的谱系转换构成了用于研究和临床应用的有吸引力的方法。谱系转换可以在没有增殖和多能祖细胞产生的情况下以直接方式进行,或者通过产生可扩展的多能祖细胞状态以间接方式进行。在这里,我们报告了一种组合的重编程方法的发展,通过一个塑料中间状态过渡,允许产生人中胚层祖细胞,同时绕过传统的多能性标志。转化的中胚层祖细胞表现出双能分化潜能,并且能够产生内皮和平滑肌谱系。重要的是,人成纤维细胞可以通过非整合方法转化为成血管细胞样祖细胞。分化的成血管细胞样细胞在体内表现出新血管生成和吻合。本文所述的间接谱系转化为成血管细胞样细胞的方法增加了旨在临床治疗缺血性病理的重编程方法的设备。
Lineage conversion of one somatic cell type into another constitutes an attractive approach for research and clinical use. Lineage conversion can proceed in a direct manner, in the absence of proliferation and multipotent progenitor generation, or in an indirect manner, by the generation of expandable multipotent progenitor states. Here we report on the development of a combined reprogramming methodology that, transitioning through a plastic intermediate state, allows for the generation of human mesodermal progenitor cells while circumventing the traditional hallmarks of pluripotency. Converted mesodermal progenitor cells demonstrated bi-potent differentiation potential and were able to generate endothelial and smooth muscle lineages. Importantly, human fibroblasts can be converted into angioblast-like progenitor cells by non-integrative approaches. Differentiated angioblast-like cells exhibit neo-angiogenesis and anastomosis in vivo. The methodology for indirect lineage conversion to angioblast-like cells described here adds to the armamentarium of reprogramming approaches aimed at the clinical treatment of ischemic pathologies.
