Pancreatic Cells (Alpha and Beta Cells)

Alpha cells (α cells): also known as α cells, are a type of endocrine cells located in the Islets of Langerhans within the pancreas. They are responsible for producing the hormone glucagon when there is a low level of glucose in the blood. Moreover, research indicates that alpha cells have a significant role in safeguarding and regenerating beta cells. 

Beta cells in the pancreas: beta cells in the pancreas have a crucial function in regulating glucose levels in the body, as they are responsible for producing insulin. These cells have a lengthy lifespan and typically do not replicate much in a person's lifetime under normal conditions. Their primary role involves synthesizing, storing, and secreting insulin, which is carefully controlled in response to fluctuations in the body's metabolic state.
