Representative flow cytometry histograms of LFA-1 (a), CD28 (c) and CD69 (e) in PMA-stimulated lymphocytes (LPMA), PMA-stimulated lymphocytes co-cultured with fibroblasts (LPMA+FA). LFA-1 (b), CD28 (d) and CD69 (f) expression in resting lymphocytes (LA), PMA-stimulated lymphocytes, PMA-stimulated lymphocytes co-cultured with fibroblasts and PMA-stimulated lymphocytes co-cultured with fibroblasts in the presence of a semipermeable membrane (LPMA+FA ins.). Data represent means ± SE of seven independent experiments in which seven different cells lines were used.
