Oxidative protein damage detection during extended DPSC culture with or without exogenous H2O2 (50–200 μM) treatment. Representative merged TRITC (red) and Hoechst nuclear stain (blue) fluorescence microscopy images of protein carbonyl detection by immunocytochemistry, for a–d high proliferative sub-population, A1 (2–10PDs), e–h low proliferative sub-population, A2 (2–10PDs), i–l low proliferative sub-population, C3 (2–10PDs), m–p low proliferative sub-population, D4 (2–10PDs), and q–t high proliferative sub-population, A1 (45–60PDs). N = 3, scale bar 100 μm, × 200 magnification
