The stem cell carries a single copy of the human genome, instead of the two copies typically found in normal stem cells. These are the first human cells that are known to be capable of cell division with just 1 copy of the parent cell’s genome. Since the stem cells were a genetic match to the egg cell donor, they could also be used to develop cell-based therapies for diseases such as blindness, diabetes, or other conditions in which genetically identical cells offer a therapeutic advantage. Because their genetic content is equivalent to germ cells, they might also be useful for reproductive purposes.
