WebWhich cells of the pancreas secrete glucagon? Glucagon is a 29-amino acid peptide hormone predominantly secreted from the alpha cells of the pancreas. Which pancreatic cell releases insulin? Insulin is released from the beta cells in your pancreas in response to rising glucose in your bloodstream. WebA small proportion (1-2 per cent) of the pancreas is made up of other types of cells called islets of Langerhans. These cells sit in tiny groups, like small islands, scattered throughout the tissue of the pancreas.
