Identifying and isolating specific cell types is crucial for several reasons: 1. Understanding Cell Function: By isolating specific cells, researchers can study their functions in detail. 2. Disease Research: Isolation of disease-associated cells helps in understanding the pathogenesis and progression of diseases. 3. Therapeutic Development: Isolated cells can be used for developing and testing new therapies. 4. Stem Cell Research: Isolating different stem cell populations is vital for regenerative medicine.
