EMBRYO BREAKTHROUGH OFFERS ALTERNATIVE SOURCE OF STEM CELLS

Scientists have created Britain'+s first "virgin conception" human embryos, writes Clive Cookson. They hope these parthenotes, as they are known technically, will be an alternative to human cloning as a source of stem cells genetically identical to the patient.
Paul De Souza told the British Association science festival in Dublin that his research team had worked with about 300 immature human eggs to make six parthenotes. The procedure involves stimulating an unfertilised egg electrically to start developing into an early embryo without the addition of any male genetic material from a sperm cell.
