(*) p<0.05 statistically significant compared to LPS stimulated macrophages. (B) Evaluation of apoptotic markers from SKOV3 cells following co-culture of untreated or stimulated J774A.1 with SKOV3 cells. (*) p<0.05 statistically significant compared to cells co-cultured with IL-4 stimulated macrophages.
