Résumé Le récent développement chez l'hydre de l'inhibition génétique par ARN
interférence, grâce à des ARNs double brin délivrés dans la nourriture, a ouvert la voie à la …

The recent establishment of gene silencing through RNA interference upon feeding opens
avenues to decipher the genetic control of regeneration in hydra. Following that approach …

Numerous developmental control genes have been isolated in a variety of organisms by
either homology cloning or system-specific strategies. Functional genetic tests, however, are …

The silencing of genes whose expression is restricted to specific cell types and/or specific
regeneration stages opens avenues to decipher the molecular control of the cellular …

Hydra continuously differentiates a sophisticated nervous system made of mechanosensory
cells (nematocytes) and sensory–motor and ganglionic neurons from interstitial stem cells …

The cnidarian Hydra is a classical model of whole-body regeneration. Historically, Hydra
apical regeneration has received more attention than its basal counterpart, most studies …

Hydra vulgaris is a small and simple aquatic animal capable of whole-body regeneration
and has negligible senescence. The entire animal, including the nervous system, is …

Hydra belongs to Cnidaria, a phylum that contains animals with radial symmetry exclusively
found in aquatic environments. The fossil evidences of embryos and larvae place the …

In animals capable of whole-body regeneration, a single bisection injury can trigger two
different types of regeneration. Currently, it is not well understood how this adaptive …

Transitions in gene regulatory processes responsible for the emergence of specialized cell
types and spatiotemporal regulation of developmental signaling prior to the divergence of …
