Retinal regeneration in amphibians.
This review is a comparative analysis of retina regeneration in different amphibians. Special attention is given to the newt, which, unlike other vertebrates, retains the capacity for the regeneration of eye structures for all life. The review focuses on the sources of the cells which contribute to retina regeneration, proliferative activity of cells participating in regeneration, the factors w...
متن کاملThe expression of Brachyury (T) during gastrulation in the marsupial frog Gastrotheca riobambae.
Gastrulation in the marsupial frog Gastrotheca riobambae has been analyzed by the distribution of the Brachyury (T) protein. Comparison with other amphibians provides mechanistic insights, since G. riobambae develops slowly and has the most divergent mode of amphibian gastrulation, producing an embryonic disk. The T pattern indicates that the prospective mesoderm is superficial, as in many amph...
متن کاملReduce, reuse, recycle - Developmental signals in spinal cord regeneration.
Anamniotes, fishes and amphibians, have the capacity to regenerate spinal cord tissue after injury, generating new neurons that mature and integrate into the spinal circuitry. Elucidating the molecular signals that promote this regeneration is a fundamental question in regeneration research. Model systems, such as salamanders and larval and adult zebrafish are used to analyse successful regener...
متن کاملSex Reversal in Amphibians.
Amphibians have been widely used to study developmental biology due to the fact that embryo development takes place independently of the maternal organism and that observations and experimental approaches are easy. Some amphibians like Xenopus became model organisms in this field. In the first part of this article, the differentiation of the gonads in amphibians and the mechanisms governing thi...
متن کاملLeft and right in the amphibian world: which way to develop and where to turn?
The last decade has seen a dramatic increase in studies on the development, function and evolution of asymmetries in vertebrates, including amphibians. Here we discuss current knowledge of behavioral and anatomical asymmetries in amphibians. Behavioral laterality in the response of both adult and larval anurans to presumed predators and competitors is strong and may be related, respectively, to...
