Pancreatic islets and transdifferentiate into beta cells in both healthy and diabetic human and mouse pancreatic islets, a possible future source for beta cell regeneration. Pancreatic islets The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (hormone-producing) cells, discovered in 1869 by German pathological anatomist Paul Langerhans. The pancreatic islets constitute 1 to 2% of the pancreas volume and receive 10–15% of its blood flow. The pancreatic islets are arranged in density routes throughout the human pancreas, and are important in the metabolism of glucose. There are about 3 million islets distributed in the
Beatrice Islets about 7500 years ago when sea levels reached current levels. The islets are composed of sand and sandgrit. The islets is part of a drying spit at low water which falls to a depth of within about to the west. As of 1987 and again in 1996, the Beatrice Islets were reported as having no vegetation as a result of an exercise to remove the infestation of South African boxthorn. While sources dated 1987 and 1996 do not explicitly list fauna for Beatrice Islets, it is likely that fauna species which are exclusively birds reported as being present on The
