(Submitter supplied) The asymmetric localization of maternal biomolecules is critical for body plan development. One of the most popular model organisms for early embryogenesis studies is Xenopus laevis but there is a lack of information in other animal species. Here, we compare the early development of two amphibian species – the frog X. laevis and the axolotl Ambystoma mexicanum. This study aimed to identify asymmetrically localized RNAs along the animal-vegetal axis during the early development of A. more...

(Submitter supplied) To investigate whether axolotl could serve as a novel model organism for the study of kidney regeneration after severe renal injury. We established tubular injury model by intraperitoneal injection of gentamicin. We then performed gene expression profiling analysis using data obtained from RNA-seq of 5 different samples from Control or gentamicin-induced injury groups.

(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) Asymmetrical localization of biomolecules inside the egg, results in uneven cell division and two daughter cells with different fates. This phenomenon is required for the establishment of many biological processes and is particularly responsible for the great variety of cell types formed during developmentand requires strict timing and positional control. The key molecules determining the body plan are the mRNAs, of which many examples have already been discovered to be asymmetrically localized during oogenesis and embryogenesis in both the amphibian and fish models. 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.
