Abstract
The relationship between urodele regeneration and the possibility of regeneration in mammals is unclear, but the idea of possible regeneration of neural elements in man is being studied because of its potential clinical importance. One of the great challenges is to gain sufficient knowledge about the basic biology of animal regeneration and to use it for the betterment of the mankind. It is known that the initial stages of urodele limb regeneration depend on the presence of intact nerve fibers connected to their cell bodies. The nerve fibers severed at the level of limb amputation regrow and penetrate the blastema, providing blastema cells with indispensable factors. These factors are produced in the perikarya of neurons and transported via their axons to the blastema. Numerous studies have been performed to elucidate the quantitative relationships between nerve fibers and limb regeneration. However, there are no reports dealing with the individual nerve cells at work. The aim of this investigation was to analyze the quantitative participation and qualitative distinctions of different nerve cells innervating the regenerating parts of the urodele limb and their possible roles in the nerve-dependent and nerve-independent periods of regeneration. The cells under study are housed in the dorsal ganglia (sensory neurons) and in the ventral part of the spinal cord gray matter (motor neurons). The direct involvement of these neurons in different regeneration periods was visualized by means of horseradish peroxidase (HRP) labeling. A total of 34 animals (21 experimental and 13 control) were used to study fluctuations in the numbers of labeled nerve cells. The results are summarized as follows: (a) the first nerve cells incorporating HRP within 5 days after amputation are found in the dorsal ganglia, whereas motor neurons in the gray matter are labeled within 7 days; (b) the number of labeled perikarya increases during the nerve-dependent regeneration period (0–21 days after amputation), with the percentage of implicated sensory neurons exceeding that found in the control series; and (c) during the next, nerve-independent period, the number of participating labeled neurons decreases gradually. Such fluctuations in the number of labeled neurons might represent the metabolic status of these cells in their effort to provide the blastema cells with the factors needed at the appropriate time. The current findings support previous observations that the periods of dependence and independence of urodele limb regeneration on the integrated control of brachial nerves reflect changes in the metabolism of individual sensory and motor neurons.
