Figure 2. Micromorphology and flow cytometry profile of pulp cells and macrophages exposed to an adhesive resin. MDPC-23, OD-21, or macrophages were exposed for 24 hrs to SingleBond light-cured for 0 sec (unpolymerized), 10 sec (partially polymerized), or 40 sec (polymerized), or untreated controls. (a–l) Phase-contrast photomicrographs of representative fields at 200x. (m–z) Flow cytometry profile of approximately 10,000 cells/condition stained with propidium iodide. The proportion of apoptotic cells per condition ("A") is depicted in the top left-hand corner of each graph.
