Scientists Use Stem Cells to Create Model Human Embryos
INTO THE FUTURE
“I’d like to emphasize that these are neither embryos, nor are we trying to make embryos actually,” Dr. Jitesh Neupane, of the University of Cambridge’s Gurdon Institute, said.
Scientists announced that they’ve been able to grow embryo-like structures made from human stem cells, featuring a heartbeat and traces of blood. The structures—made without the need for egg, sperm or fertilization—replicated some of the cells that would appear in early pregnancy.
