A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem cell biologist Jacob Hanna.
He and his team at the Weizmann Institute of Science in Israel have taken steps toward probing that puzzle. Last year, they announced they had grown a synthetic human embryo, equivalent to a 14-day-old human embryo, in the lab without the aid of a human sperm or egg cell.
The discovery may serve as a model for better understanding the earliest days of human development, potentially helping scientists to grow organs and tissues for transplant down the line. Hanna, who was named to...
