Scientists have created human embryos that are genetic copies of living people to make stem cells, potentially treating diseases but raising cloning concerns. The method, detailed in Cell, uses somatic cell nuclear transfer to create embryonic stem cells. The research, led by Shoukhrat Mitalipov at Oregon Health & Science University, has sparked ethical debates and calls for regulation. The study involved 23 scientists and used donor eggs to create stem cell lines, including from a patient with Leigh syndrome. The findings highlight the need for federal rules on therapeutic cloning and egg donation practices.
