Final answer:
The transformation of acinar cells of the pancreas into pancreatic beta cells is an example of cell differentiation.
Step-by-step explanation:
The transformation of acinar cells of the pancreas into pancreatic beta cells is an example of cell differentiation.
In this case, the acinar cells undergo a process called metaplasia, where they change their structure and function to become beta cells. This transformation allows the pancreas to produce insulin, which is essential for regulating blood glucose levels.
