Bone marrow cells from 5 mice of each genotype were pooled, and Kit+ cells were purified using Cd117 microbead kit on AutoMACS separator (Miltenyi). Kit+ cells were flow sorted on MoFlo sorter (Beckman Coulter), to obtain LSK (Lin-Kit+Sca1+) cells. Sorted cells were resuspended at 1000/μL density in 1x PBS with 0.04% BSA. Cells were subjected to droplet bead capture, followed by cell lysis, reverse transcription, and amplification according to TotalSeqA protocol from 10X Genomics (Pleasanton, CA).
