Islet cells are a type of cell found in the pancreas that are responsible for producing and secreting hormones, particularly insulin. These cells play a crucial role in regulating blood sugar levels and are essential for the proper functioning of the body's metabolic processes. Research on islet cells focuses on understanding their function, development, and potential implications for various diseases such as diabetes. This research area aims to improve treatments and therapies for conditions related to insulin dysregulation and to enhance our understanding of the underlying mechanisms of these disorders.
