The culturing and use of human pluripotent stem cells is controversial because the natural source of such cells is embryos, which are destroyed by the process of extraction.

人类多功能干细胞的培养和使用备受争议，因为这类细胞的自然来源胚胎，在提取过程中会被破坏。

To Loring's surprise, however, the corresponding human genes did transform both animals' cells into embryonic-like stem cells called induced pluripotent stem cells (iPS cells).

然而令Loring惊喜的是，相应的人类基因确实能把这两种动物的细胞转换成称为诱导多能干细胞(iPS细胞)的类胚胎干细胞。

I feel these cells are pluripotent like human embryonic stem cells.

我感觉这些细胞像人胚胎干细胞一样是多能的。

Induced pluripotent stem cells can come from any cell in the human body, including skin cells, so they don't have the moral quandaries surrounding them.
