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.

Islets and skerries in the Faroes Islets and skerries in the Faroes Besides the 18 islands of the Faroes there are also several islets and skerries. The Faroe Islands consist of 779 islands, islets and skerries. The islets are small and are geographical parts of the larger islands. Suðuroy consists of 263 islands, islets and skerries, which is the largest number. The islets are measured in square hectometers (hectares), the largest being comparable in size to the smallest island, Lítla Dímun. Here is a list of the largest islets: 1. Tindhólmur (65,0 sqhm), at Sørvágur Vágar 2. Mykineshólmur (45,0 sqhm), at Mykines 3. Trøllhøvdi (19,0 sqhm),
