19-P040 Molecular analysis of spinal cord regeneration in Axolotl
sue is known as transdifferentiation, in which the local cells are able to dedifferentiate (lose the characteristics of their origin) and subsequently redifferentiate. Our lab has shown by transient lineage tracing that spinal cord cells (radial glial cells) can migrate into surrounding tissues and contribute to non-neural cells during regeneration [Science 298 (2002) 1993–1996]. In order to fo...
متن کاملEfficient gene knockin in axolotl and its use to test the role of satellite cells in limb regeneration.
Salamanders exhibit extensive regenerative capacities and serve as a unique model in regeneration research. However, due to the lack of targeted gene knockin approaches, it has been difficult to label and manipulate some of the cell populations that are crucial for understanding the mechanisms underlying regeneration. Here we have established highly efficient gene knockin approaches in the axol...
متن کاملIdentification of Conserved and Novel MicroRNAs during Tail Regeneration in the Mexican Axolotl
The Mexican axolotl salamander (Ambystoma mexicanum) is one member of a select group of vertebrate animals that have retained the amazing ability to regenerate multiple body parts. In addition to being an important model system for regeneration, the axolotl has also contributed extensively to studies of basic development. While many genes known to play key roles during development have now been...
متن کاملFundamental differences in dedifferentiation and stem cell recruitment during skeletal muscle regeneration in two salamander species.
Salamanders regenerate appendages via a progenitor pool called the blastema. The cellular mechanisms underlying regeneration of muscle have been much debated but have remained unclear. Here we applied Cre-loxP genetic fate mapping to skeletal muscle during limb regeneration in two salamander species, Notophthalmus viridescens (newt) and Ambystoma mexicanum (axolotl). Remarkably, we found that m...
متن کاملChemical activation of Wnt/β-catenin signalling inhibits innervation and causes skeletal tissue malformations during axolotl limb regeneration
Limb regeneration involves several interrelated physiological processes in which a particular signalling pathway may play a variety of functions. Blocking the function of Wnt/β-catenin signalling during limb regeneration inhibits regeneration in axolotls (Ambystoma mexicanum). Limb development shares many features with limb regeneration, and Wnt/β-catenin activation has different effects depend...
