Dual origins for neural cells during development of the <i>Clytia</i> planula larva Open
Adult hydrozoan cnidarians undergo extensive tissue turnover, generating neural cell types including nematocytes (stinging cells) from interstitial stem cells (i-cells) expressing stemness proteins such as Piwi and Nanos. The contribution …

Cross-species analysis of ARPP19 phosphorylation during oocyte meiotic maturation charts the emergence of a new cAMP-dependent role in vertebrates Open
In many animal species, elevated cAMP-PKA signaling initiates oocyte meiotic maturation upon hormonal stimulation, whereas in vertebrates, it acts as a negative regulator of this process. To address this “cAMP paradox”, we have focused on …

Whole-animal multiplexed single-cell RNA-seq reveals transcriptional shifts across <i>Clytia</i> medusa cell types Open
Whole-organism perturbations reveal single-cell responses across the Clytia medusa.

Whole Animal Multiplexed Single-Cell RNA-Seq Reveals Plasticity of<i>Clytia</i>Medusa Cell Types Open
We present an organism-wide, transcriptomic cell atlas of the hydrozoan medusa Clytia hemisphaerica , and determine how its component cell types respond to starvation. Utilizing multiplexed scRNA-seq, in which individual animals were index…

Pattern regulation in a regenerating jellyfish Open
Jellyfish, with their tetraradial symmetry, offer a novel paradigm for addressing patterning mechanisms during regeneration. Here we show that an interplay between mechanical forces, cell migration and proliferation allows jellyfish fragme…

A G protein–coupled receptor mediates neuropeptide-induced oocyte maturation in the jellyfish Clytia Open
The reproductive hormones that trigger oocyte meiotic maturation and release from the ovary vary greatly between animal species. Identification of receptors for these maturation-inducing hormones (MIHs) and understanding how they initiate …

An improved whole life cycle culture protocol for the hydrozoan genetic model <i>Clytia hemisphaerica</i> Open
The jellyfish species Clytia hemisphaerica (Cnidaria, Hydrozoa) has emerged as a new experimental model animal in the last decade. Favorable characteristics include a fully transparent body suitable for microscopy, daily gamete production …

Cell shape changes during larval body plan development in <i>Clytia hemisphaerica</i> Open
The cnidarian “planula” larva shows radial symmetry around a polarized, oral-aboral, body axis and comprises two epithelia cell layers, ectodermal and endodermal. This simple body plan is set up during gastrulation, a process which proceed…

The genome of the jellyfish <i>Clytia hemisphaerica</i> and the evolution of the cnidarian life-cycle Open
Jellyfish (medusae) are a distinctive life-cycle stage of medusozoan cnidarians. They are major marine predators, with integrated neurosensory, muscular and organ systems. The genetic foundations of this complex form are largely unknown. W…
