(The Conversation) – A recent report shows new healthy eggs can be made from stem cells. Stem cells are present in human embryos, as embryonic stem cells, and in most organs including the ovary. Alternatively, an induced form of stem cells can be obtained by treating mature cells with a cocktail of reagents in the laboratory. The procedures required to create new eggs out of stem cells are very complex and still experimental. There are ethical issues, such as the need to destroy a human embryo to obtain embryonic stem cells, and further experiments will be necessary to show there are no genetic or fertility problems with subsequent generations.
