The cytoplasm of mucous epithelium cells of the intestinal track was full of a large number of highly electron-dense and obvious mitochondria as well as abundant pinocytotic vesicle bodies (Fig.
Cytoplasm contained abundant mitochondria and pinocytotic vesicles. Epithelium of posterior intestine was thin, translucent and squamous with dense blood capillary network underground, while there were no folds on mucous membrane surface.
The apical cytoplasmic membrane forms pinocytotic pits, and the subapical cytoplasm contains numerous pinocytotic vesicles. RER is well developed in the cytoplasm, GA is located in the supranucleus zone, and lipid droplets are concentrated in the middle and basal parts.
The apical cytoplasmic membrane has pi-nocytotic pits, and the apical cytoplasm contains a GA and pinocytotic vesicles. An oval nucleus with a large nucleolus is located in the middle of the cell.
The presence of pinocytotic vesicles in the apical cytoplasm is evidence that these cells are involved in the absorption of nutrients (Byrne, 1994), while the presence of phagosomes indicates that intracellular digestion may be one of their functions.
The small pits observed scattered over the cell surface probably represent pinocytotic vesicles, previously documented (SVEDBERGH & BILL, 1972).
Intracytoplasmic pinocytotic vesicles were rarely found.
Some investigators observed typical characteristics of smooth muscle cells, including well-formed external laminae, pinocytotic vesicles, numerous cytoplasmic thin filaments, and subplasmalemmal dense patches.
An oval nucleus that bulges in the centre of the cell, cilia (between one to four per cell), openings of pinocytotic vesicles, microvilli, border bars and border cell with zig-zag appearance due to the interdigitations, were observed.
Pinocytotic vesicles openings were observed, with similar characteristics to previous reports, ie.
Pinocytotic vesicles were found beneath the plasma membranes, and cytoplasmic organelles were sparse, although swollen mitochondria, rough endoplasmic reticulum, lysosomes, and occasional collections of intermediate filaments were noted (Figure 4).
With ultrastructural observations of the intestinal muscle coat of mouse and bat, Yamamoto[8] summarized the character of the ICC as being (1) slender cytoplasmic processes, (2) ample free ribosomes, (3) numerous pinocytotic vesicles, and (4) a basement membrane that incompletely or completely covered them.
