Developmental Biology, 2008 Nematogenesis, the production of stinging cells (nematocytes) in Cnidaria, can be considered as a model neurogenic process. Most molecular data concern the freshwater polyp Hydra, in which nematocyte production is scattered throughout the body column ectoderm, the mature cells then migrating to the tentacles.

Developmental Biology, 2009 Egg animal-vegetal polarity in cnidarians is less pronounced than in most bilaterian species, and its normal alignment with the future embryonic axis can be disturbed by low-speed centrifugation. We have analyzed the development of oocyte polarity within the transparent and autonomously functioning gonads of Clytia medusae, focusing on the localization

Comparison of cell types across life cycle stages of the hydrozoan Clytia hemisphaerica
, 2022 The hydrozoan Clytia hemisphaerica displays a typical tri-phasic hydrozoan life cycle including a vegetatively propagating polyp colony and free-swimming medusa form as the sexually reproductive life stage. Male and female jellyfish spawn daily, triggered by light and after fertilisation a ciliated planula larva forms in about one day. After three days

, 2017 20 mM hydroxyurea treatment completely inhibits cell division in the Clytia medusa exumbrella. 7 day old animals were labeled with EdU for 24 h in the absence (A,B) or presence (C,D) of 20 mM hydroxyurea. B and D show Hoechst staining in the same animals in A and C, respectively. Scale bar = 50 μm (PPTX 824 kb)

, 2017 Labeling index of cells in the exumbrella. EdU incorporation showed that in the first 3–4 days after release there is very little, if any, division in epithelial cells in the exumbrella. In contrast, at 7 days the percentage of cells dividing within a 24 h period is >40%.

, 2017 Actin in lamellipodia of epithelial cells at a wound site. Wounded animals were fixed and stained with phalloidin, and imaged using a Zeiss 710 laser confocal microscope. Lamellipodia can be seen extending from intact marginal cells and from pieces of cells in the wound gap. Scale bar = 50 μm. (PPTX 879 kb)

Light-induced oocyte maturation in the hydrozoan clytia hemisphaerica
, 2017 Tight control of oocyte maturation and of gamete release is essential for successful sexual reproduction in the animal kingdom. These processes are precisely coordinated by endocrine and/or environmental cues, depending on the species, but much remains to be learned about their regulation.

Cellular and molecular basis of regeneration in the medusa Clytia hemisphaerica
, 2019 La méduse hydrozoaire Clytia hemisphaerica a une plasticité lui permettant de répondre efficacement à différents types de blessure. Au cours de ma thèse, je me suis intéressée aux processus cellulaires et moléculaires au cours de la régénération de l’organe digestif regroupant la bouche et l’estomac (appelé ‘manubrium’) chez cette méduse.
