Pseudocysts of the pancreas are abnormal collections of fluid, dead tissue, pancreatic enzymes, and blood that can lead to a painful mass in the pancreas. 1  About this Condition.
The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (i.e., hormone-producing) cells. Discovered in 1869 by German pathological anatomist Paul Langerhans, the pancreatic islets constitute approximately 1-2% of the pancreas's mass and receive 10-15% of its blood flow.ormones produced in the pancreatic islets are secreted directly into the blood flow by (at least) five types of cells. In rat islets, endocrine cell subsets are distributed as follows: 1  Alpha cells producing glucagon (15â20% of total islet cells). 2  Beta cells producing insulin and amylin (65â80%).
