2009 NOV 3 -- Researchers detail in 'Electric currents in Xenopus tadpole tail regeneration,' new data in life sciences. "Xenopus laevis tadpoles can regenerate tail, including spinal cord, after partial amputation, but lose this ability during a specific period around stage 45. They regain this ability after stage 45," scientists in the United States report.
"What happens during this 'refractory period' might hold the key to spinal cord regeneration. We hypothesize that electric currents at amputated stumps play significant roles in tail regeneration. We measured electric current at tail stumps following amputation at different developmental stages. Amputation...
