library_construction_protocol: Fresh bone marrow mononuclear cells were isolated by the Ficoll-PaqueTM PLUS (GE Healthcare) following the manufacturer's instruction. Bone marrow samples were divided into two parts. One part was used for sorting HSPCs which were stained with human antibodies including lineage cocktail (CD3, CD14, CD16, CD19, CD20, CD56) (BV510, Biolegend), CD34 (APC, Clone 581, BD Biosciences), CD38 (PE-Cy™7, clone HIT2, BD Biosciences), CD90 (PerCP-Cy™5.5, clone5E10, BD Biosciences), CD45RA (FITC, clone HI100, BD Biosciences), CD49f (BV605, clone GoH3, BD Bioscience), CD10 (BV786, clone HI10a, BD Biosciences), CD135 (PE, clone 4G8, BD Biosciences). Another part of bone marrow and all peripheral blood were used for sorting T cells which were stained antibodies including CD3 (APC-Cy™7, clone SK7, BD Biosciences), CD4 (APC, clone RPA-T4, BD Biosciences), CD8 (PE-Cy™7, clone RPA-T8, BD Biosciences). All samples were incubated on ice for 30mins in the dark and washed with PBS. After cell suspension, DAPI (1 ug/ml, Sigma-Aldrich) was added to remove dead cells for FACS. Flow cytometry sorting was performed on a BD FACSAria III (BD Bioscience). Fresh isolated cells were sorted directly into cell lysis buffer on a BD FACSAria III. The reverse transcription and template switch steps were performed following the modified Smart-seq2 protocol.(STRT-seq). Single cells with different barcodes were pooled for one library. The mixed cDNA was purified using DNA Clean and Concentration Kit (ZYMO, Cat.#D4014), and the small fragments and primers were removed by 0.8X AMPure XP beads (Beckman, Catt#A63882). A total of 30~40 ng purified products were amplified using biotinylated primers anchored with 8 nt sequences for library indexing. 300~450 ng cDNA was fragmented into 300 bp using Covaris S220 (Covaris). Dynabeads MyOne Streptavidin C1 (Invitrogen, Cat#65001) was used to enrich the 3' end of fragmented cDNA. The processes of end repair, polyA-tailing, adaptor ligation and library amplification were using KAPA Hyper Prep Kits (Kapa Biosystems, Cat#KK8504) and NEBNext Multiplex Oligos for Illumina (Index Primers Set 1) (NEB, Cat#E7335L).
