CD30L, a cytokine that induces proliferation of T cells.

Erythropoietin has a range of actions including vasoconstriction-dependent hypertension, stimulating angiogenesis, and inducing proliferation of smooth muscle fibers.

An intriguing property of IL-12 is its capacity to induce proliferation by cytolytic T cell only upon co-stimulation with antigen.

It will thereby induce its own uncontrolled proliferation (autocrine loop), and proliferation of neighboring cells.

Estrogen also induces growth of the uterus, proliferation of the endometrium, and menses.

Under normal conditions, this signaling ultimately induces regulated cell growth and proliferation.

The difficulty of isolating Schwann cells and subsequently inducing proliferation is a large obstacle.

While the former induces activation and proliferation, the latter causes differentiation of proliferating satellite cells.

In the endometrium, the tendency of "estrogens" to induce proliferation is opposed by progesterone (or patentable "progestins").

Proliferation of these cells is more limited, although cerebral ischemia can induce proliferation at this stage.
