Fig. 7: Fate mapping of alternative platelet replenishment pathways.

a, Flt3Cre-tdTomato labeling (mean ± s.e.m.) of blood lineages in steady-state Flt3Cretg/+ R26Tom/+ Vwf-eGFPtg/+ Gata1-eGFPtg/+ mice (n = 7; 8–13 weeks old): platelets (CD150+CD41+TER119−), erythrocytes (TER119+CD150−CD41−), myeloid (granulocyte) cells (CD11b+GR1+CD41−NK1.1−CD19−CD4/CD8a−), B lymphocytes (CD19+CD41−NK1.1−CD4/CD8a−CD11b−GR1−) and T lymphocytes (CD4/CD8a+CD41−NK1.1−CD11b−GR1−CD19−). Dots represent individual mice. Tom, tdTomato. b, Representative profiles of Flt3Cre-tdTomato labeling in platelets (left) and mean ± s.e.m. labeling of all lineages (right) replenished by a single CD45.2 Vwf-eGFP− multi-HSC (top; n = 14) and Vwf-eGFP+ platelet-restricted P-HSC (bottom; n = 14) 18–21 weeks after transplantation.
