According to Scientists Gene-Engineer First Human Stem Cells, scientists deleted a disease gene from human embryonic stem cells:
Scientists said on Sunday they had, for the first time, genetically manipulated human stem cells — a step toward making the body’s so-called master cells into a useful tool.Using the method that made the laboratory mouse so valuable to genetic researchers, the team at the University of Wisconsin deleted a disease gene from human embryonic stem cells.
I still feel “knockout mouse” sounds much cooler than “knockout human”…
