The majority of animal phyla have species that can regenerate. Comparing regeneration
across animals can reconstruct the molecular and cellular evolutionary history of this …

Somatic genetic variation (SoGV) may play a consequential yet underappreciated role in
long-lived, modular species among plants, animals, and fungi. Recent genomic data …

The epithelial and interstitial stem cells of the freshwater polyp Hydra are the best-
characterized stem cell systems in any cnidarian, providing valuable insight into cell type …

In most animals, pluripotency is irreversibly lost post gastrulation. By this stage, all
embryonic cells have already committed either to one of the somatic lineages (ectoderm …

Hydractinia is a colonial marine hydroid that shows remarkable biological properties,
including the capacity to regenerate its entire body throughout its lifetime, a process made …

Neurogenesis is the generation of neurons from stem cells, a process that is regulated by
SoxB transcription factors (TFs) in many animals. Although the roles of these TFs are well …

Cnidarians are> 600 million years old and are considered the sister group of Bilateria based
on numerous molecular phylogenetic studies. Apart from Hydra, the genomes of all major …

Cell fate stability is essential to maintaining" law and order" in complex animals. However,
high stability comes at the cost of reduced plasticity and, by extension, poor regenerative …

Environmental stressors are assessed through methods that quantify their impacts on a wide
range of metrics including species density, growth rates, reproduction, behaviour and …

Hydractinia, a genus of colonial marine cnidarians, has been used as a model organism for
developmental biology and comparative immunology for over a century. It was this animal …
