Figure 4. TUNEL positive cells in the distal lungs of the P 21 rat pups.

Figure 4

(A): TUNEL positive cells were labeled with FITC (green) and the cell nuclei were labeled with propidium iodide (red) (Scale bar; 25 µm). (B): Number of observed TUNEL positive cells per high power field. NC, Normoxia control group; HC, hyperoxia control group; HT3, hyperoxia with stem cell transplantation group at P3; HT10, hyperoxia with stem cell treatment group at P10; HT3+10, hyperoxia with stem cell treatment group at P3 and P10. Data; mean±SEM. * P<0.05 compared to NC, # P<0.05 compared to HC,† P<0.05 compared to HT3, ‡ P<0.05 compared to HT10.
