Genetic testing of embryos
WHAT: The confluence of advances in human genetics
and reproductive science has resulted in the ability to perform genetic tests on embryos produced by in vitro fertilization. Embryos found to be free of a disease-causing gene mutation can then be selectively implanted into a woman's womb to initiat...
Researchers look to stem cell therapy and bone marrow transplants to find a cure for diabetes
