Limb regeneration.
Limb regeneration is observed in certain members of the animal phyla. Some animals keep this ability during their entire life while others lose it at some time during development. How do animals regenerate limbs? Is it possible to find unifying, conserved mechanisms of limb regeneration or have different species evolved distinct means of replacing a lost limb? How is limb regeneration similar o...
متن کاملCyclosporine Effects on Chick Limb Bud Mesenchyme and DNA Content
Background: Cyclosporine A (CsA) is a powerful immunosuppressive agent, which is used for the prevention of allograft rejection and for the treatment of autoimmune diseases. Many transplant recipients must take this medicine for the rest of their lives. Females in reproductive age group on prolonged CsA therapy have legitimate concerns about drug effects on pregnancy. Objective: To explore Cs...
متن کاملLimb regeneration revisited
The investigation of vertebrate limb regeneration, a favorite topic of early developmental biologists, is enjoying a renaissance thanks to recently developed molecular and genetic tools, as indicated in recent papers in BMC Biology and BMC Developmental Biology. Classical experiments provide a rich context for interpreting modern functional studies.
متن کاملProximodistal patterning during limb regeneration.
Regeneration is an ability that has been observed extensively throughout metazoan phylogeny. Amongst vertebrates, the urodele amphibians stand out for their exceptional capacity to regenerate body parts such as the limb. During this process, only the missing portion of the limb is precisely replaced--amputation in the upper arm results in regeneration of the entire limb, while amputation at the...
متن کاملMechanisms 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...
