incubated with blocking antibodies (Human TruStain FcX, BioLegend; 422302
and Mouse TruStain fcX anti-mouse CD16/32, BioLegend; 101320) for 15 min,
followed by incubation with V450 Mouse Anti-Human CD45 Clone HI30 (BD
Biosciences, 560367), PE-eFluor 610 mCD45 Monoclonal Antibody (30-F11)
(Thermo Fisher, 61-0451-82), FITC anti-human CD235a Antibody (BioLegend,
349104), PE anti-human CD33 Antibody (366608, BioLegend), APC anti-human
CD19 Antibody (BioLegend, 302212), PE/Cy7 anti-human CD3 antibody
(BioLegend, 300420), FITC anti-human CD34 antibody (BioLegend, 343504) and
Fixable Viability Dye eFluor 780 for live/dead staining (Thermo Fisher,
65-0865-14). Percentage human engraftment was calculated as hCD45+
cells/(hCD45+ cells + mCD45+ cells). B cells (CD19+) and myeloid (CD33+)
lineages were gated on the hCD45+ population. HSPCs (CD34+) and T cells
(CD3+) were gated on the hCD45+CD19-CD33-population.
hCD45+CD19-CD33-CD34-CD3-population was referred as lineage-. FACS analysis
and sorting of CD34+ / CD19+ cells were done using the FACSAria II machine
(BD Biosciences).
