Which hormone helps in mitotic cell division?

The hormone that plays a significant role in promoting mitotic cell division is insulin-like growth factor 1 (IGF-1). IGF-1 is produced primarily in the liver and is stimulated by growth hormone. It helps regulate cell growth and division by promoting protein synthesis and cellular proliferation, thereby facilitating tissue growth and repair. Additionally, other hormones like estrogen and testosterone can also influence cell division in specific tissues.
