Fig. 4. Fluorescence co-localization images of senescence RAW 264.7 cells (a and b) and Caov-3 cells (c and d). The cells were co-incubated 100 nM Lyso-Tracker Green (a and c) or Mito-Tracker Green (b and d) and 10 μM SA-HCy-1 for 30 minutes. RAW 264.7 cells were pretreated with 0.1 μM DOX for 3 days. For the NIR channel: λex = 628 nm, λem = 670–730 nm; for the green channel: λex = 488 nm, λem = 500–540 nm, scale bar = 25 μm.
