Elemento esqueletico calcareo poliforme que se encuentra en la mesoglea
y tambien en el eje de Scleraxonia.
Masson's trichrome (Sumner & Sumner, 1969) was suggested by Manuel (1981) as a general stain for Anthozoa, allowing for a good contrast between the mesoglea
and the cellular regions.
Among cnidarians, the ECM has a variety of functions, but it mainly provides support for tissues, and it is the principal visible structure in the acellular mesoglea
The gastroderm tissues of the mesenteries and the solenia are separated from the surrounding mesoglea
by collagen-rich basal lamina (Menzel et al.
Similarly, in some cnidarians, including gorgonians, scleractinian corals, and sea anemones, amoebocytes are recruited from the mesoglea
to the wound site, and these cells engage in phagocytosis (Hutton and Smith, 1996; Meszaros and Bigger, 1999; Olano and Bigger, 2000; Henry and Hart, 2005; Mydlarz et al.
1b) distributed throughout the body, mainly within the mesoglea
At the interradii, the tissue sheets are connected to the bell mesoglea
, but the circular, striated muscle sheets are continuous, showing no interruptions (Fig.
Like the cnidae that they support, the epithelial cells in anemones are unusually tall and thin, secreting and supported by an unusually fibrous and structured mesoglea
which almost qualifies as connective tissue (Hyman, 1940; Chapman, 1966; Gosline, 1971; Koehl, 1977).
Larger anemones also have thicker mesoglea
(Shick, 1991; Francis, 2004), which can support a thicker attached layer of tissue and larger nematocysts (i.
In both symbiotic and aposymbiotic tentacles, preimmune controls showed light brown staining in epidermal and gastrodermal tissues, and no staining in the mesoglea
Their soft body makes it easy to separate ectodermal epithelium from associated mesoglea
to further localize enzyme activity to specific tissues.
A more serious problem is that these bubbles will slowly work themselves through the mesoglea
, which can lead to infection.
