Culture and initial characterization of the secretory response of neoplastic cat mast cells
1992
Mohr, F.C. | Dunston, S.K.
Mast cells isolated from feline splenic mastocytomas were cultured to study their structural and functional properties. isolated cells from various cats were grown as monolayer cultures for a mean of 56 days (range, 30 to 76 days). Cat mast cells released allergic mediators in response to compound 48/80, anti-cat serum antibodies, and concanavalin A. On the basis of the finding that secretion from cat mast cells was stimulated by anti-cat serum antibodies and concanavalin A, these cells contain surface-bound immunoglobulins. The presence of mast cell-sensitizing antibodies has been suspected in cats, but never before directly demonstrated. Cultured cat mast cells have cytochemical and functional characteristics common to connective tissue-type mast cells and provide one of the few non-rodent models of cultured cells for the study of this type of mast cell.
