This study shows that adaptive immune cells are not required for appendage regeneration in axolotls and zebrafish, with regeneration proceeding normally despite the absence of mature T and B cells.

This study identifies SYCP2's closure motif as essential for HORMAD2 recruitment to chromosome axes, revealing its role in meiotic synapsis quality control in mice.

This study investigates the functional differences between thymic and peripheral Treg cells in visceral adipose tissue, showing that tTreg instability contributes to inflammation and obesity while pTreg cells protect against metabolic disorders.

The paper presents the chromosome-scale assembly of the giant Pleurodeles waltl genome, revealing insights into its expansion and regeneration-related genes.

The paper shows that passage 1 human iPSC-derived RPE cells form more extensive monolayers after transplantation compared to passage 2 cells, highlighting a subpopulation with higher transplantation potential.

This study shows that primate-specific EPIREGULIN expression enhances basal progenitor proliferation in the developing neocortex, contributing to increased brain size across species.

This study shows that cellular senescence promotes progenitor cell expansion during axolotl limb regeneration by creating a pro-proliferative niche and modulating Wnt signaling.

The paper identifies Tig1 as a regulator of proximo-distal identity during salamander limb regeneration through single-cell RNAseq analysis.

This study maps β-cell regeneration in zebrafish using single-cell transcriptomics, identifying hybrid β/δ cells as key contributors to diabetes recovery.

The paper uses single-cell transcriptomics to reveal heterogeneity in zebrafish thyroid thyrocytes and characterizes surrounding cell types.

The paper uses single-cell transcriptomics to analyze how Amyloid-beta42 and Interleukin-4 affect neural stem/progenitor cell plasticity in adult zebrafish brain, identifying gene expression changes and cell-cell communication alterations.
