Meaning and Definition
A substance, often a protein, that stimulates cell division (mitosis).
Any chemical or biological agent that triggers a cell to commence cell division, thereby leading to cell proliferation. In immunology, it refers to agents that stimulate lymphocyte proliferation.

- Misspelling as 'mitogin' or 'mitogene'. Incorrectly using it as a synonym for any growth factor (some, but not all, growth factors are mitogens).
FAQ
Frequently Asked Questions
Not exactly. While many growth factors are mitogens (they induce mitosis), the term 'mitogen' is defined by its function (triggering division), whereas 'growth factor' is a broader class of signaling molecules that may promote growth, differentiation, or survival, not necessarily division.
Yes, context is key. For example, some bacterial toxins can act as potent mitogens for specific immune cells, triggering a harmful over-proliferation as part of their pathogenic mechanism.
In advanced biology, biochemistry, or immunology textbooks, university laboratory manuals, and research articles focusing on cell proliferation or immune response assays.
Yes. Common laboratory mitogens include Phytohaemagglutinin (PHA), Concanavalin A (ConA), Pokeweed Mitogen (PWM), and Lipopolysaccharide (LPS for specific cell types), used to test immune cell responsiveness.
