Changes throughout time in the lineage content of clones regenerated in secondary mice. (A) Changes through time in the total size of each barcoded (GFP⁺) clone detected in the 2 secondary mice. Clone #110 (red line) and clone #96 (blue line) are shown separately. Gray shaded region denotes the limit of detection by MPS. (B) Relative contributions of GM, B-, and T-cells to clones #110 and #96 over time in the secondary mice as compared with the primary mouse in which they were first seen.
