Contour diagram of FITC-Annexin V/PI double staining by flow cytometry. The three quadrants represent different cells conditions the upper right quadrant (R1), nonviable, late apoptotic, and necrotic cells (FITC+/PI+); lower left quadrant (R2), viable cells (FITC−/PI−) and lower right quadrant (R3), early apoptotic cells (FITC+/PI−). (a) Untreated control HDFs. (b) CV-treated HDFs.
