title: Amputation level and hind limb regeneration in larvae of the Egyptian toad Bufo regularis Reuss: length, volume and rate.
abstract: Study of the influence of the amputation level on regeneration length and volume and on the rate of regeneration of the hind limbs of a larval stage of Bufo regularis revealed that, during dedifferentiation and blastema accumulation and growth, the parts regenerating from proximal and distal amputation levels were almost the same length and volume, and grew at the same rate, irrespective of the amputation level. During blastema differentiation and morphogenesis, however, there were significant length, volume and elongation rate differences between parts regenerating from different amputation levels. The results also demonstrated that there was a strong positive correlation between regeneration length and volume, but that the elongation rate was not correlated to regeneration volume.
