title: The effects of tumour extract on macrophage proliferation in lymph-nodes.
abstract: Injection of a soluble tumour extract induces mitosis in sinus macrophages of the draining lymph-node. This is not abolished by irradiation; the stimulus also induces monocytosis somewhat later. These findings make it likely that the stimulus induces mitosis in the resident lymph-node macrophage population.
