Retrieved riana Eunjung Cha Cloning advance using stem cells from human adult reopens ethical questions Washington Post. Dolly was bound for fame from the time she was born in essays on real estate market 1996. Doi :.1186/gb reviews1023. 27 28 There is also the potential for treating diseases associated with mutations in mitochondrial DNA. This ability allows stem cells to create any cell type, which could then be transplanted to replace damaged or destroyed cells. Thus, though legal, scnt cannot be federally funded.
The first extinct species was cloned in 2009. Shanghai announced the successful cloning of two female crab-eating macaques (named, zhong Zhong and Hua Hua ) from fetal nuclei. One problem with iPSCs is that they can't be used to treat people with mitochondrial diseases.
