NMR-based metabonomic analysis of HUVEC cells during replicative senescence

Figure 4. Heatmap of significant metabolites in the five groups of HUVEC cells. The significant metabolites were identified from the OPLS-DA S-plots of the four groups of cells vs. the P3 group. Red/blue colors indicate increased/decreased metabolite levels.
