Fig. 6. Mitochondrial NAD+, NADH, NADP+, and NADPH levels in primary P5 and senescent P25 and P35 fibroblasts. Levels of (A) NAD+, (B) NADH, (C) NAD+/NADH ratio, (D) NADP+, (E) NADPH, and (F) NADP+/NADPH ratio in young (P5) and senescent (P25 and P35) confluent cells. **p < 0.01, ***p < 0.001, and ****p < 0.0001 indicate significant difference from control P5 values (n = 6).
