Transforming growth factor: beta signaling is essential for limb regeneration in axolotls. [PDF]

PLoS ONE, 2007
Axolotls (urodele amphibians) have the unique ability, among vertebrates, to perfectly regenerate many parts of their body including limbs, tail, jaw and spinal cord following injury or amputation. The axolotl limb is the most widely used structure as an

A developmentally regulated switch from stem cells to dedifferentiation for limb muscle regeneration in newts

Nature Communications, 2016
How limb regeneration in the newt is regulated at a cellular level is much debated. Here, the authors show different mechanisms acting at different developmental stages, namely stem/progenitor cells in larval regeneration and muscle fibres in the ...

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Data on chemical activation of Wnt/β-catenin during axolotl limb regeneration

Data in Brief, 2017
Limb amputation in axolotls was performed to obtain data demonstrating that a chemical agonist of Wnt (int-related protein)/β-catenin signalling can have a role in axolotl limb regeneration (Wischin et al., 2017) [1].

Mechanisms of urodele limb regeneration [PDF]

Regeneration, 2017
AbstractThis 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.

Neural control of growth and size in the axolotl limb regenerate

eLife, 2021
The mechanisms that regulate growth and size of the regenerating limb in tetrapods such as the Mexican axolotl are unknown. Upon the completion of the developmental stages of regeneration, when the regenerative organ known as the blastema completes ...

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

Advanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

miR-20487-5p/SERCA1/MAPK/ERK Pathway Regulates Newt Limb Regeneration

Biology
Cynops orientalis, a member of the Salamandridae family, can regenerate severely injured limbs throughout its lifespan. The molecular mechanisms regulating limb regeneration in C. orientalis remain largely unknown.
