Cells in close proximity to the mesogleal layer typically become more compact and contain abundant vesicles along with other dense granules (Fig.
The mesogleal layer is defined with a distinct inner and outer border and contains multiple muscle cells arranged in fascicles (Figs.
Oogenesis: Stage I oocytes were small, ovoid or rounded and the main characteristic was the presence of a thin, bluish-transparent mesogleal
layer surrounding the egg (Fig.

organization and collagen synthesis in the sea anemone Aiptasia diaphana.
In cryosections, quinones and quinoproteins stained blue in the outermost ectodermal epithelium cells and in oblong cells with large granules in the mesogleal cell cords (Fig.
2C) were localized mainly in the granular cell layer immediately below the ectodermal epithelium, with some cells in the mesogleal cell cords also staining positive (Fig.

canals of Zoanthus robustus?
There was no evidence of any sym32 label within the mesogleal
layer, and the pattern of distribution of the sym32-containing vesicles in the epidermal cells was distinct from that in the gastrodermis.
The Sigma Scan program was also used to determine the percentage of each labeled section that was epithelial tissue or mesogleal
Effect of salinity on osmolality of mesogleal
The other site of abundant immunoreactivity was the mesogleal
nerve net, a meshwork of neurons and amoebocytes embedded in the collagen-based jelly, the meso-glea, that separates ectoderm from endoderm [ILLUSTRATION FOR FIGURE 6D OMITTED].
Research into the true biological roles and phylogenetic status of the mesogleal
amoebocytes is hampered by the small, and often variable, number of the cells in anthozoans and the difficulty of their isolation for in vitro analysis (Patterson and Landolt, 1974; Van der Vyver, 1981).
