A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs able to give rise to early human embryos, researchers report September 30 in Nature Communications.

The effort is the latest attempt to make eggs and sperm from human cells. Researchers have already succeeded in making these important cell types from many types of animals,
