Islets biology
WitrynaMost of the cells of the pancreas secrete digestive enzymes (exocrine function) but throughout the organ, there are small sections of cells known as the islets of Langerhans that produce hormones (endocrine function) The islets of Langerhans contain two cell types: alpha cells, which secrete glucagon, and beta cells, which secrete insulin Witryna23 sie 2024 · Correlation between simulation data and experimentally measured islet viability was examined. Using these in vitro viability data of human islets, the effect of islet diameter and oxygen tension of the culture environment on islet viability was also analyzed using a logistic regression model.
