Jellyfish are known for their remarkable regenerative abilities. This study shows that in the jellyfish Cladonema, following tentacle amputation, repair-specific proliferating cells robustly form a...

As the sister group to bilaterians, cnidarians stand in a unique phylogenetic position that provides insights into evolutionary aspects of animal development, physiology, and behavior. While cnidar...

Jellyfish have existed on the earth for around 600 million years and have evolved in response to environmental changes. Hydrozoan jellyfish, members of phylum Cnidaria, exist in multiple life stages,...

Blastema formation is a crucial process that provides a cellular source for regenerating tissues and organs. While bilaterians have diversified blastema formation methods, its mechanisms in non-bil...

体のどこを切っても再生する動物「プラナリア」をご存じだろうか。体を何カ所かで切断しても、1週間ほどで断片の一つ一つがそれぞれ個体に成長するという、なんとも不思議な動物だ。プラナリアをはじめ、こう...

これまで脱分化は組織の損傷再生時や腫瘍形成時に起こることが知られていたが，生理的な環境変化に対して起こりうるかは不明だった．今回，われわれは絶食からの再摂食という栄養環境の変化に応答した脱分化現象とそのメカニズムを同定し，脱分化が栄養環境に対する腸管の適応成長を司ることを明らかにした．

Adult tissues in Metazoa dynamically remodel their structures in response to environmental challenges including sudden injury, pathogen infection, and nutritional fluctuation, while maintaining qui...

The remarkable regenerative abilities observed in planarians and cnidarians are closely linked to the active proliferation of adult stem cells and the precise differentiation of their progeny, both...

Nature Communications - The presence of cancer can induce systemic disruption of the host homeostasis. Here, the authors show that different solid tumours remotely increase hepatic...

The sea anemone Nematostella vectensis (Anthozoa, Cnidaria) is a powerful model for characterizing the evolution of genes functioning in venom and ...

Researchers have unveiled an intriguing phenomenon of cellular reprogramming in mature adult organs, shedding light on a novel mechanism of adaptive growth.

Nature Communications - The mechanisms underlying cell plasticity remain poorly understood. Here, Guo et.al discover that intestinal cells in the fly gut can alter their fates through the loss of a...
