Insulin-secreting cell

In medicine and physiology, insulin-secreting cells, also called pancreatic beta cells, are a "type of pancreatic cell representing about 50-80% of the islet cells. Beta cells secrete insulin."

Beta cell function (HOMA-B) can be measured by:

${\text{HOMA-IR}}={\frac {20*{\text{fasting insulin}}}{{\text{fasting plasma glucose}}-3.5}}$
