Skin Cell Into Sperm Or Egg? Human Induced Plurtipotent Stem Cells Reprogrammed Into Germ Cell Precursors

For the first time, researchers have reprogrammed human induced pluripotent stem cells into the cells that eventually become eggs and sperm, possibly opening the door for new treatments for infertility using patient-specific cells. Theoretically, an infertile patient's skin cells, for example, could be taken and reprogrammed into iPS cells, which, like embryonic stem cells, have the ability to become every cell type in the human body. Those cells could then be transformed into germ line precursor cells that would eventually become eggs and sperm.
