[Release of antigens into the culture medium by LS fibroblasts in culture].
LS fibroblasts cultivated for 1 or more days in unsupplemented Eagle's MEM release antigens into the medium, without showing any evidence of lysis, but on the contrary continuing to proliferate. These antigens give up to three precipitation lines when tested by means of immunodiffusion and immunoelectrophoresis against specific rabbit antisera; one or two of them give identity reactions with antigens obtained by repeatedly washing the fibroblasts with balanced salt solutions. Evidence has been obtained that they are surface components, easily stripped or spontaneously shed by the cells.
