BioNews - Breakthrough in stem cell research - world's first reprogrammed adult cell: US scientists have for the first time created 'personalised' human embryonic stem cell (hESCs) using a form of cloning. The result is a significant milestone on the route to using stem cell-based therapies but the researchers stress more work is to be done as genetic errors in the cells means they are not yet suitable for therapeutic use.
The researchers used a technique called somatic cell nuclear transfer (cloning) to create an egg that contains genetic material taken from the intended recipient of the resulting stem cells. The egg then reprograms the cell so that it begins to divide like a developing embryo to produce a blastocyst from which stem cells can be collected.
