Pancreatic islets isolation [electronic resource] : from the mouse to the clinic / Miriam Ramírez-Domínguez, editor.
Pancreatic islets make up the endocrine pancreas and they contain the only source of insulin in the body, beta cells. Hence, access to high quality preparations of pancreatic islets is fundamental for in vitro studies and to test pre-clinical applications in animal models in vivo. Access to healthy...
