Changes in Bioelectric Signals Trigger Formation of New Organs: Tadpoles Made to Grow Eyes in Back, Tail, Tufts University Study

For the first time, scientists have altered natural bioelectrical communication among cells to directly specify the type of new organ to be created at a particular location within a vertebrate organism. Using genetic manipulation of membrane voltage in Xenopus (frog) embryos, biologists at Tufts University's School of Arts and Sciences were able to cause tadpoles to grow eyes outside of the head area.
