Mean fluorescence lifetime, metabolic index and FLIRR1 for NAD(P)H and flavins within co-cultivated HaCaT and SCC4 cells. NAD(P)H fluorescence decay was fitted biexponentially with fixed lifetimes τ1 = 400 ps and τ2 = 2.5 ns, the flavin fluorescence decay was fitted three exponentially with free lifetimes τi.
| NAD(P)H τmean (ps) |
Flavins τmean (ps) |
Metabolic Index (NAD(P)H a1/NAD(P)H a2) |
FLIRR1 (NAD(P)H a2/flavins a1) | |
|---|---|---|---|---|
| HaCaT | 1154 ± 51 | 704 ± 90 | 1.8 ± 0.2 | 0.49 ± 0.03 |
| SCC4 | 1099 ± 47 | 673 ± 89 | 2.0 ± 0.2 | 0.46 ± 0.03 |
The statistical significance between HaCaT and SCC4 cell lines was evaluated using one-way ANOVA test. The p-value was 0.012 for the metabolic index and 0.007 for FLIRR1.
