Epsilon cell Epsilon cell Epsilon cells (ε-cells) are endocrine cells found in the Islets of Langerhans and produce the hormone ghrelin. They were discovered in mice. In human fetal pancreases, single epsilon cells scattered in primitive exocrine tissue were observed to start aggregating into clusters after gestational week 13. From gestational week 21, epsilon cells were observed around developing islets, forming an almost continuous layer at the rim of the islets. In adult pancreas samples, they remained localized on the mantle of the islets in different amounts. Production of ghrelin with insulin, glucagon, or somatostatin was not detected during development.

Wild Wind Islets are the short-tailed shearwater, (20,000 pairs), fairy prion (3000 pairs), common diving-petrel (3000 pairs) and silver gull. The white-bellied sea-eagle has nested there. The metallic skink is present. Wild Wind Islets The Wild Wind Islets comprise a group of five steep rocky unpopulated islets located close to the south-western coast of Tasmania, Australia. Situated some south of where the mouth of Port Davey meets the Southern Ocean, the islets are one of the eight islands that comprise the Mutton Bird Islands Group. The Wild Wind Islets are part of the Southwest National Park and the Tasmanian Wilderness World Heritage Site.
