Figure 2 – Impact of heterogeneity on population dynamics.

(A) Assuming precursor input is negligible, homogeneity in the net loss rate across the population leads to a single exponential decay function (Eq. 2). (B) Conversely, if there is heterogeneity in net loss among cell subsets (e.g. due to different death rates), then the observed decay (dashed line) reflects the sum of the decay kinetics of each subset (red and blue lines).
