It is important to note that oocytes presenting different characteristics can be physically close to one another and also close to apparently healthy oocytes in the same acinus (Fig.
For a comprehensive analysis, we studied two organs in comparison with the pancreas but focused mainly on the endothelial damage in microvasculature of the (pancreatic islet of Langerhans), (glomerular capsule Bowman's capsule) and the liver acinus, using the expression of CD34.
The pancreatic acinus were tubular or vesicular, and formed the peripheral gland cells, as well as the middle centroacinar cells.

Although some studies investigated the effects of diabetes and/or menopause, it was hard to find the sufficient analysis that examined morphological changes, the content of secretion or stereological analysis of acinus epithelium on parotid gland with diabetic or ovaryectomized effects.
Measurements were made of the acinus diameter in male and female gonads, and of spermatozoid acrosome length.
The acinar cells secrete a fluid that contains water, electrolytes, mucus, and enzymes, all of which flow out of the acinus into collecting ducts.
