(Submitter supplied) The mandible plays an essential part in human life and, thus, defects in this structure can dramatically impair the quality of life in patients. Axolotls, unlike humans, are capable of regenerating their lower jaws; however, the underlying mechanisms and their similarity to those in limb regeneration are unknown. In this work, we used morphological, histological, and transcriptomic approaches to analyze the regeneration of lateral resection defects in the axolotl mandible. more...

(Submitter supplied) Regenerating limbs retain their proximodistal (PD) positional identity following amputation. This positional identity is encoded genetically by PD patterning genes, which instruct blastema cells to regenerate the appropriate PD limb segment. Retinoic acid (RA) is known to specify proximal limb identity, but how RA concentration is established in the blastema is unknown. Here, we show that RA breakdown via CYP26B1 is essential for determining the RA concentration within blastemas. more...

(Submitter supplied) Humans and other tetrapods are considered to require apical-ectodermal-ridge, AER, cells for limb development, and AER-like cells are suggested to be re-formed to initiate limb regeneration. Paradoxically, the presence of AER in the axolotl, the primary regeneration model organism, remains controversial. Here, by leveraging a single-cell transcriptomics-based multi-species atlas, composed of axolotl, human, mouse, chicken, and frog cells, we first established that axolotls contain cells with AER characteristics. more...

(Submitter supplied) Axolotl limb regeneration proceeds through the formation of a blastema, a mound of progenitor cells that accumulate at the end of the amputated stump. These progenitor cells expand and later undergo patterning to regenerate the missing limb, restoring both form and function. A subset of cells within the blastema become senescent, a state of permanent growth arrest. Here, we address the functional relevance of cellular senescence to axolotl limb regeneration, through a combination of gain- and loss-of-function assays. more...

(Submitter supplied) An outstanding mystery in biology is why some species, such as the axolotl, can regenerate tissues whereas mammals cannot1. Here, we demonstrate that rapid activation of protein synthesis is a unique feature of the injury response critical for limb regeneration in the axolotl (Ambystoma mexicanum). By applying polysome sequencing, we identify hundreds of transcripts, including antioxidants and ribosome components that are selectively activated at the level of translation from pre-existing messenger RNAs in response to injury. more...

(Submitter supplied) The salamander limb regenerates only the missing portion. Each limb segment can only form segments equivalent to- or more distal to their own identity, relying on a property termed “positional information”. How positional information is encoded in limb cells has been unknown. By cell-type-specific chromatin profiling of upper arm, lower arm, and hand, we found segment-specific levels of histone H3K27me3 at limb homeoprotein gene loci but not their upstream regulators, constituting an intrinsic segment information code. more...

(Submitter supplied) Amphibians such as the salamanders and the African clawed frog Xenopus are great models for regeneration studies because they can fully regenerate their lost organs. While axolotl can regenerate damaged organs throughout its lifetime, Xenopus has a limited regeneration capacity after metamorphosis. The ecotropic viral integrative factor 5 (Evi5), a cell-cycle-regulated protein that prevents cells from entering mitosis prematurely, is of great interest for it is highly upregulated in the limb blastema of axolotls, but its expression level remains unchanged in the fibroblastema of postmetamorphic frogs. more...

We performed gene expression profiling of over 1 million single cells across 19 tissues to construct the first adult axolotl cell landscape. Comparison of single-cell transcriptomes between the tissues of neotenic and metamorphosed axolotls revealed the heterogeneity of non-immune parenchymal cells in different tissues and established their regulatory network. more...

We report that at 27 days after a retinectomy (early-mid regeneration), regenerating axolotl retinas exhibit downregulation of genes associated with neuronal networks but upregulation of genes associated with angiogenesis and the extracellular matrix. We also report differential expression of two Notch pathway effector genes, Hes1 and Hes5.

(Submitter supplied) Salamanders have the remarkable ability to functionally regenerate after spinal cord transection. In response to injury, GFAP+ glial cells in the axolotl spinal cord proliferate and migrate to replace the missing neural tube and create a permissive environment for axon regeneration. In this paper we show that miR-200a acts to repress expression of Brachyury in sox2 positive progenitor cells in the axoltol spinal cord after spinal cord injury but after tail amputation when multiple tissue types must be regenerated then mir-200a is downregualted allowing progenitor cells in the spinal cord to naturally become bipotent progenitors which can give rise to muscle and neural cell types. more...

(Submitter supplied) Salamander limb regeneration is an accurate process which gives rise exclusively to the missing structures, irrespective of the amputation level. This suggests that cells in the stump have an awareness of their spatial location, a property termed ‘positional identity’. Little is known about how positional identity is encoded, in salamanders or other biological systems. Through single-cell RNAseq analysis, we identified Tig1/RARRES1 as a potential determinant of proximal identity. more...
