What is the function of growth hormones in cell culturing?

Growth hormones play a crucial role in cell culturing, primarily by stimulating various cellular processes that are essential for growth and replication. In the context of cell culturing, these hormones are particularly important for initiating and promoting cell division, which is a fundamental requirement for the expansion of cell populations in vitro.

When growth hormones are introduced into a culture medium, they bind to specific receptors on the cell surface, triggering signaling pathways that lead to DNA replication and cell cycle progression. This process is vital for researchers and biotechnologists who rely on the successful proliferation of cells for experiments, production of biological materials, or for therapeutic applications.

While other processes such as cell differentiation, maintenance of viability, and even inhibition of cell division can also be influenced by hormonal factors, the key function of growth hormones specifically in cell culturing is to enhance the rate of cell division, thereby contributing to the overall growth of cell populations in cultures.
