Mean +/- SD exchange fluxes intervals from NCI-60 exometabolomics data.

Includes glucose, lactate, XTP, pyruvate, formate, and amino acids, from which we derive constraints for our model. Minus (-) symbolizes uptake while plus (+) symbolizes secretion. Experimentally induced constraints are separated into two kinds: hard constraints (red bold font) and desired observations (normal font), indicating different types of logical constraints.
