Scientists Create Living Entities in The Lab That Closely Resemble Human Embryos Director of Research Ethics Insoo Hyun asks, at what point does an embryo model become a real embryo? March 19, 2021 "For decades, science has been trying to unlock the mysteries of how a single cell becomes a fully formed human being and what goes wrong to cause genetic diseases, miscarriages and infertility. Now, scientists have created living entities in their labs that resemble human embryos; the results of two new experiments are the most complete such "model embryos" developed to date. The goal of the experiments is to gain important insights into early human development and find new ways to prevent birth defects and miscarriages and treat fertility problems."
