B-1 phenotype of peripheral CD19+ Mac-1+ B cells of a representative recipient of DL1-Fc 2.5-activated ESC-HSC_Fig.1E, S1B, S2A-B

B-1 phenotype of peripheral CD19+ Mac-1+ B cells of a representative recipient of DL1-Fc 2.5-activated ESC-HSC at 31 weeks post-transplant. B-1 cells (green gate) were mostly of B-1b (CD5?) subtype
