Japanese regulators just quietly gave researchers there a historic OK to generate human embryos from stem cells in the lab — no ovaries or testes needed. Scientists in Japan and around the world are quickly working toward making viable human eggs and sperm from stem cells, a process called in vitro gametogenesis, or IVG. Those stem cell-derived sperm and eggs …
