Proliferative activity is essential for several reasons:
1. Tissue Growth: During development, tissues and organs grow through the proliferation of cells. 2. Tissue Repair: After injury, cells proliferate to replace damaged tissues. 3. Cancer Diagnosis: High proliferative activity is a hallmark of cancer. Measuring it can aid in diagnosing and determining the aggressiveness of tumors. 4. Research: Understanding proliferative activity helps in studying various biological processes and developing therapeutic interventions.
