Abstract
In Rana ridibunda, digits regenerate from the proliferation of skeletal tissues (cartilaginous or periosteal) and never from a blastema as is the case in Urodela. However, these chondroblastic regenerates have a very limited growth in normal conditions. Experiments have shown that the growth period of these regenerates, and hence their size, can be enhanced by injections of collagenase (which affects the reorganization of conjunctive matrices) or growth hormone (which favors the proliferation of chondrocytes). These neoformations seem to depend on factors that differ from those that influence the blastematic regenerates found in Urodela (which depend on the nervous system) and their growth is thus more directly affected by the conditions that control the metabolism of chondroblastic tissues.[Journal translation]
