Insulin is secreted by what cells
NettetInsulin is secreted in primarily in response to elevated blood concentrations of glucose. This makes sense because insulin is "in charge" of facilitating glucose entry into cells. Some neural stimuli (e.g. sight and taste of food) and increased blood concentrations of other fuel molecules, including amino acids and fatty acids, also promote ... Nettet9. apr. 2024 · After about 3 weeks of in vitro induction, IPCs formed microspheres of 100-200 μm, with > 95% viable cells that were dithizone stain positive. IPCs expressed islet-related genes and proteins, and secreted high levels of insulin whether stimulated by low or high levels of glucose.
