In vitro synthesis of gamma M-like globulin by various chick embryonic cells.

Abstract

Mass cultures of cells derived from bursa of Fabricius, yolk sac and thigh muscle of 16-day chick embryos, and from the peripheral blood of adult chickens, and cloned chick embryonic muscle cells synthesize and release into the nutrient medium a protein which has the antigenic and physico-chemical characteristics of chicken γM-globulin.
