La rigenerazione del midollo spinale della coda di larve di Xenopus laevis in seguito ad amputazioni ripetute
In the present work, tadpoles of Xenopus laevis were submitted to successive removal of 70% of the tail. The structure of the regenerated spinal cord and the evolution of the regenerative process was compared with, those of tadpoles submitted to one amputation. The results obtained demonstrated that: 1) Either after one amputation or after two or three amputations, the regenerative process exhibits the same phases: a) migratory phase, b) multiplicative phase, c) differentialve phase. 2) Either...
