Figure 3From: Clonogenic growth of human breast cancer cells co-cultured in direct contact with serum-activated fibroblastsResults of flow cytometric measurements of proliferation and apoptosis. There was a distinct peak of (b) breast cancer cells with a high proliferative rate compared with (a) breast cancer cells cultured without fibroblasts. (c) Tumor cells grown on fibroblasts had a significantly higher proliferative rate and a lower apoptotic rate than did tumor cells cultured alone.Back to article page
