The effect of drug‐induced mast cell secretion on proliferation was studied in fibroblast‐like and mesothelial‐like cells in organ‐cultured rat mesentery. Mast cell degranulation achieved by Compound 48/80 was followed by a marked mitogenic reaction in the surrounding tissue cells. The drug itself lacked mitogenic effect on cultured guinea‐pig mesentery, the mast cells of which are unresponsive to the drug, and on a human normal fibroblast‐like cell line. In contrast, histamine at about 10 −10 M, a major mast cell component, induced marked mitogenesis in guinea‐pig mesentery without causing degranulation of mast cells. It is concluded that secreting rat‐tissue mast cells release a mitogenic factor or factors acting locally on nearby tissue cells.
