Scientists Make Human Stem Cells Through Cloning

•, Jennifer Welsh
 "Our finding offers new ways of generating stem cells for patients with dysfunctional or damaged tissues and organs," study researcher Shoukhrat Mitalipov of Oregon Health & Science University, said in a press release. "Such stem cells can regenerate and replace those damaged cells and tissues and alleviate diseases that affect millions of people."

This technique they used to make these stem cells is called somatic cell nuclear transfer, and is the same technique used to clone animals, like Dolly the sheep.

To put it in very simplified terms: the researchers first harvest a human egg from a woman's ovaries and completely remove her genetic material from the egg. Then, they take a human skin cell and insert it into the egg using an inactivated virus which fuses the two cells. The embryo that grows from this would be a genetic copy of the person that donated the cell.
