Clinical trials: B Cells
Type1 Diabetes Mellitus
PET-CT Scan Method to Monitor Pancreatic B-Cell Loss in Diabetes Mellitus
The pancreas is an organ that plays major roles in the digestion of food. A part of the pancreas called islet beta-cells produces insulin, which regulates the amount of glucose (a sugar) present in the blood at all times.
