The apical cytoplasm of the epithelial cells was thrown into by a continuous striated border of microvilli (Fig.
In this study, the apical cytoplasm of epithelial cells was covered by a continuous striated border of microvilli which is in accord with the findings of Abdul-Gahaffor et al., in the pigeon.
The cytoplasm has large vacuoles weakly acidophilous, and the apical cell surface presents striated border (Fig.
The cell apex has a striated border and the cell cytoplasm was predominantly acidophilic.
Epithelial cells of the posterior midgut are each characterized by the presence of a well-developed striated border relative to the digestive cells of the anterior midgut, which suggests a role of nutrient absorption; moreover the occurrence of apocrine secretion or release of cytoplasmic vesicles into the lumen was not observed.
Posterior midgut epithelial cells containing vacuoles and striated border (arrow) on the apical surface and regenerative cells (r) in the basal portion.
The inner epidermis of the transitional area between the marginal and middle mantle is a simple columnar layer with a well-developed
striated border on the free surface (Fig.
The histological sections were used to measure the height of digestive cells, the length of the striated border, the nuclear area and the area of the regenerative cell nests.
flavicincta was formed by a single layer of columnar digestive cells with a well-developed striated border and oval nuclei possessing 1 or 2 evident nucleoli.
Alcian blue/PAS (AB/PAS) histochemical test showed a strong reaction to PAS in the striated border and cytoplasmic granules in the apical portion of digestive cells.
The anterior midgut region showed longer digestive cells (34 [+ or -] 4.6 [micro]m) and a longer striated border (3.6 [+ or -] 0.6 [micro]m) than the posterior midgut region [(P < 0.05) (Figs.
A well-developed
striated border was formed on the free surface of the epithelial layer (Fig.
