![]() vectensis, while others may play a role in regulating proliferation during regeneration. The integrins expressed in the gonads may play roles in mediating sperm-egg interactions in N. Nematostella is a cnidarian (corals, jellyfish, hydras, sea anemones, etc.) animal that was originally targeted by EvoDevo researchers looking to identify a cnidarian animal to which the development of bilaterians (insects. Our observations confirm that complex patterns of integrin expression were already present in basal metazoans. This protocol describes a reliable method for inducing spawning in the starlet sea anemone Nematostella vectensis under laboratory conditions. This review highlights the rise of one such novel model system, the starlet sea anemone Nematostella vectensis. ![]() One of the β subunits is expressed 8-fold higher during regeneration, and its expression is observed in cells within both the epidermis and the gastrodermis at the site of regeneration. Changes in expression were also studied 48 h after horizontal transection by quantitative reverse transcription PCR and in situ hybridization. The three β subunits each have distinctive patterns of expression: one is concentrated in the gonad and mesenteric filament, another is found in a subset of cells in the epidermis of the oral region and in a subset of gastrodermal cells in the mesenteries, and a third is expressed widely. The α subunit is primarily expressed in cells near muscles, by a subset of gastrodermal cells, and in the gonad. The expression of one of the α subunits and three of the β subunits was confirmed by reverse transcription PCR and in situ hybridization. Its known range includes the south and east coasts of Britain on the Northeast Atlantic (Sheader et al. The starlet sea anemone is a species of small sea anemone in the family Edwardsiidae native to the east coast of the United States, with introduced. ![]() The β subunits cluster with the previously described β integrins of the hard coral Acropora millepora. Nematostella vectensis (Starlet Sea Anemone) is a small estuarine mud-dwelling sea anemone with a somewhat enigmatic distribution. vectensis is a useful model to examine neuropeptide function during development, because genomic and. Phylogenetic analysis suggests that the α subunits are most closely related to RGD- and LDV-dependent α subunits of chordates. Among cnidarians, the starlet sea anemone N. Here we describe two α subunits and four β subunits from the starlet sea anemone Nematostella vectensis. Integrins are extracellular matrix receptors composed of α and β subunits.
