The hydroid Hydractinia: a versatile, informative cnidarian representative

Abstract: The Cnidaria represent the most ancient eumetazoan phylum. Members of this group possess typical animal cells and tissues such as sensory cells, nerve cells, muscle cells and epithelia. Due to their unique phylogenetic position, cnidarians have traditionally been used as a reference group in various comparative studies. We propose the colonial marine hydroid, Hydractinia, as a convenient, versatile platform for basic and applied research in developmental biology, reproduction, immunology, environmental studies… Show more

“…In mature colonies, CEL expression resumed but was restricted to only few cells. A Hydractinia colony is mainly composed of two polyp types, feeding polyps (gastrozooids) and sexual polyps (gonozooids), both emerging from the gastrovascular network, the stolons (Frank et al, 2001). Sexual polyps do not feed but contain the gonads.…”

“…Two North Atlantic sibling species, H. echinata and H. symbiolongicarpus have been studied since decades, mainly in the context of development and allorecognition (Frank et al, 2001). Hydractinia's stem cells, called interstitial cells or i-cells, are pluripotent and are repeated carbohydrate recognition domains (CRD) of about 95 amino acid residues including eight conserved cysteines (Hosono et al, 1999).…”

“…The availability of mutants is one of the features fostering the choice of Hydractinia echinata (Cnidaria: Hydrozoa) as a cnidarian model organism in studies on the evolution of genes, developmental mechanisms, and allorecognition (Frank et al, 2001). Hydractinia is a colonial species; the colony consists of hydra-like feeding polyps (gastrozooids) and sexual polyps (gonozooids); these polyps are all interconnected with each other through a network of gastro-vascular channels, termed stolons.…”

“…Basic knowledge about processes acting downstream of the induction of metamorphosis is available (for review see Frank et al, 2001;Müller and Leitz, 2002). Neurosensory cells transfer internally the external signal via the phosphatidyl-inositol-PKC transduction cascade (Leitz and Müller, 1987).…”
