Cell proliferation is the process by which cells multiply and divide to create new cells. It is a crucial process for growth, development, and maintenance of tissues in the body. Cell proliferation is tightly regulated by various signaling pathways and checkpoints to ensure that the right number of cells are produced at the right time. Abnormal cell proliferation can lead to diseases such as cancer. Researchers study cell proliferation to understand the mechanisms involved, develop new therapies, and improve treatment outcomes for diseases related to cell proliferation.
