Figure 4. Effect of donor age and cilostazol on red blood cell ATP release in normoxia and hypoxia.

Figure 4.

A: extracellular ATP (i.e., ATP release) from RBCs of older adults trended towards being lower compared to young adults during hypoxia with DMF (control; P = 0.07) and was significantly lower with cilostazol. Cilostazol had no effect on extracellular ATP from RBCs of young or older adults during normoxia or hypoxia. B: the mean percent increase in extracellular ATP from normoxia to hypoxia was impaired from RBCs of older adults in both the DMF (control) and cilostazol conditions. †P < 0.05 vs. young (within condition); ‡P < 0.05 vs. normoxia (within condition)
