Cell differentiation

Definition

Cell differentiation is the process by which unspecialized cells, such as stem cells, develop into specialized cells with distinct functions and characteristics. This crucial biological process is essential for the formation of various tissues and organs during development, playing a key role in tissue engineering by enabling the creation of specific cell types needed for regenerative medicine and therapeutic applications.
