beta cell

n.
1. Any of the insulin-producing cells of the islets of Langerhans in the pancreas.
2. Any of the basophilic chromophil cells located in the anterior lobe of the pituitary gland.

beta cell

A pancreatic endocrine cell that comprises up to 80% of the cells in the islets of Langerhans, which produces and releases insulin. Beta cells are destroyed or dysfunctional in type-1 diabetes, function suboptimally in type-2 diabetes and become neoplastic in insulinomas. Beta cells were once distinguished solely on the basis of differential staining from other cells designated A, C and D

beta cell

1. Any of the insulin-secreting cells of the pancreas that constitute the bulk of the islets of Langerhans. Synonym: B cell
2. A basophil cell of the adenohypophysis (anterior pituitary gland).
