Haelan-induced apoptosis in pancreatic carcinoma cells and fibroblasts. CAPAN-1 cells a, b, BxPC-3 cells c, d, AR42J cells e, f and fibroblasts g, h were incubated with or without 8 % Haelan and dually stained with sulforhodamine-labeled caspase inhibitor, SR-VAD-FMK, and DAPI. The representative micrographs demonstrate only few red-colored apoptotic cells in the control groups and a much greater number of red-colored apoptotic cells in the Haelan-treated groups when analyzed after 24 h (n = 2); (original magnification x 10)
