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.

Also known as Île aux deux Cocos, the island, located off the southern coast of Grand Port, is named after the two abandoned coconut plantations it houses.

Both of these relatively large islands, lying to the east of Mauritius and considered part of Flacq, become temporarily merged at low tide. The islets are an increasingly popular
