The vacuoles may reflect excretory function or pinocytotic vesicles; in other molluscs, these are thought to be involved in glucose resorption (Taylor & Andrews 1987, Andrews 1988).
Weiss and Enzinger (2) identified multiple endothelial structures on electron microscopy, including elaborate junctional attachments, pinocytotic vesicles, investing basal lamina, and Weibel-Palade bodies.
In addition, type II epithelial microvilli were missing or shortened, lamellar bodies were empty, chromatin was found at the periphery of nuclei, vascular endothelial cells were swollen and there were more pinocytotic vesicles.

The electronic microscopy specimen in the control group showed the presence of thin endothelial cell cytoplasm and pinocytotic vesicles and organelles.
FSBM induces significantly lower morphological changes such as disintegration of microvilli, absence of granulated pinocytotic vacuoles, etc in fingerling rainbow trouts (Yamamoto et al., 2010).
Hence, most promising drug delivery through brain capillaries is possible by augmentation of pinocytotic vesicles.
The ultrastructure of fully developed lymphatic endothelium is characterized by the presence of many cisternae of Golgi complexes, pinocytotic vesicles, vacuoles, cytoplasmic microfilaments and anchoring filaments, and the lack of basement membrane [52, 53].
Electron microscopy findings suggest tumour cells with well-defined basement membrane, scattered electron dense condensations in the plasma membrane, abundant glycogen, and pinocytotic vesicles and cytoplasmic filaments [24].
