Mechanisms of urodele limb regeneration
This review explores the historical and current state of our knowledge about urodele limb regeneration. Topics discussed are (1) blastema formation by the proteolytic histolysis of limb tissues to release resident stem cells and mononucleate cells that undergo dedifferentiation, cell cycle entry and accumulation under the apical epidermal cap. (2) The origin, phenotypic memory, and positional m...
متن کاملExpression of pax-6 during urodele eye development and lens regeneration.
Regeneration of eye tissues, such as lens, seen in some urodeles involves dedifferentiation of the dorsal pigmented epithelium and subsequent differentiation to lens cells. Such spatial regulation implies possible action of genes known to be specific for particular cell lineages and/or axis. Hox genes have been the best examples of genes for such actions. We have, therefore, investigated the po...
متن کاملDigit regeneration in the amphibian--Triturus cristatus.
Digit regeneration has been examined in Triturus cristatus. Because of their size, blastemas that form after digit amputation are relatively a lot more suitable for quantitative studies that involve for example the counting of cells in histological sections. They are also very useful for the study of some basic histological aspects of regeneration particularly cartilage formation. This has been...
متن کاملInfluence of Temperature on Rate of Regeneration in the Time-graded Regeneration Field in Planarians
INTRODUCTION THERE exists in planarians a time-graded regeneration field for head regeneration (Brandsted, 1946, 1956; A. & H. V. Brondsted, 1952). The characteristics of this field, expressed by rate of regeneration, are species-specific. The existence of this field ensures harmonious regeneration from cuts everywhere in the body, as a cut will always expose a 'high point' where regeneration o...
متن کاملAmputation Level - Dependent Patterning in Urodele Limb Regeneration
Comparison of mesopodial skeletal patterns found in native and regenerated limbs of the salamander Plethodon cinereus reveals variant patterns unique to each group. Variant patterns in native limbs are based on fusions between laterally adjacent elements (i.e., in the anteroposterior axis). Variant patterns in the rnesopodia of regenerated limbs usually exhibit fusions among proximodistally adj...
