Major advance in stem cell research / Controversial step in regenerative medicine reported

Major advance in stem cell research / Controversial step in regenerative medicine reported: “Biologists in South Korea reported Thursday the creation of the first stem cell lines engineered to carry the DNA of patients with chronic disease and injury, a development hailed by some as perhaps the most significant technical advance for regenerative medicine since stem cells were isolated from human embryos in 1998.”

========================

Pretty wild. They must put patient DNA in host embryo’s (like they do with frog oocytes) and get them to differentiate. That way the cells match the host and could potentially be used as implants.
