Reconciling Estimates of Cell Proliferation from Stable Isotope Labeling Experiments

Deuterium enrichment in plasma glucose in one-day and seven-day D2-glucose labeling studies of humans.
The measured enrichment in plasma glucose in the one-day (grey circles) and seven-day (black diamonds) D2-glucose labeling studies. The end of the one-day and seven-day labeling periods are marked by a dashed grey line and a dotted black line respectively. Although subjects in the one-day labeling experiment (N = 8) received approximately twice as much deuterated glucose per day as subjects in the seven-day labeling study (N = 4), their median label enrichment is only slightly higher. Median plasma glucose enrichment in the one-day labeling study = 23%, median plasma glucose enrichment in the seven-day labeling study = 17%.
