PWM

Abbreviation for pokeweed mitogen.

mitogen

(mi'to-jen)
A plant-derived protein used in the laboratory to stimulate cell division (mitosis). It is frequently used in vitro to study the proliferation of lymphocytes from blood drawn during a research study. The most commonly used mitogens are phytohemagglutinin and concanavalin A. See: concanavalin A; lectin; phytohemagglutinin

pokeweed mitogen

Abbreviation: PWM
A mitogen isolated from the pokeweed plant, Phytolacca americana. In the presence of T lymphocytes, it has the capacity to induce primed B lymphocytes to proliferate and differentiate into plasma cells.
