Cell Proliferation and Cell Death

---

Cell proliferation refers to the process by which cells divide and multiply, leading to an increase in cell number. This is essential for normal growth and development, as well as tissue repair and regeneration. However, sometimes cells can also undergo programmed cell death, known as apoptosis, which is a natural process that helps to remove damaged or unwanted cells. Both cell proliferation and cell death play important roles in maintaining tissue homeostasis and preventing disease. Dysfunction in these processes can contribute to various disorders, including cancer.
