Effects of SMA-ZnPP (styrene maleic acid-micelle-encapsulated zinc-protopoaphyrin) on viability of neoplastic mast cells. HMC-1.1 cells and HMC-1.2 cells were cultured in control medium (left panels) or medium containing SMA-ZnPP (right panels) for 72 hours. Cells cultured in SMA-ZnPP showed signs clearly characteristic of apoptosis. See the complete figure in the article beginning on page .
