Curcuma longa Is Able to Induce Apoptotic Cell Death of Pterygium-Derived Human Keratinocytes

Figure 7

Annexin-V/PI evaluation in human keratinocytes derived from pterygium explants. (a) Flow cytometric dot plots of one representative experiment. Apoptotic cells can be discriminated from viable, late apoptotic or necrotic cells according to their fluorescence emission. B3: viable cells; B4: early apoptotic cells; B2: late apoptotic cells; B1: necrotic cells. (b) The histogram shows the fold increase of Annexin-/, Annexin-/, and Annexin-/ cells ± SD of three independent experiments ( BCA versus C; CL versus C; CL versus BCA; BCA versus CL).
