FACS selection protocol: Antibody staining and FACS.For FACS purification of erythroid progenitors, lineage-depleted fetal liver cells were stained with the following: Propidium Iodide (Sigma), APC or PE-Cy7 anti-CD117 (clone ACK2, E-Biosciences), PE anti-CD71 (clone R127217, E-Biosciences), PE anti-CD24 (clone M1/69, E-biosciences), FITC streptavidin (E-Biosciences).   Flow cytometry for erythroid differentiation markers was performed on a FACS Fortessa cytometer (BD) Single cell transcriptome library preparation.  SmartSeq2 library prep was performed by depositing single cells in PCR plate wells by FACS.  Single cells were lysed in TCL buffer (Qiagen), containing RNase inhibitor (Clontech), Oligo-dT (5'-AAGCAGTGGTATCAACGCAGAGTACT30VN-3', IDT), and dNTPs (Invitrogen).  Lysates were then reverse transcribed at 42 deg C with SuperScript II reverse transcriptase (Invitrogen) in the presence of First-Strand Buffer (Invitrogen) containing DTT (Invitrogen), betaine (Sigma), magnesium chloride (Sigma), and template switching oligonucleotide (5' -AAGCAGTGGTATCAACGCAGAGTACATrGrG+G-3' where rG = riboguanosine, and +G = LNA-modified guanosine, Exiqon/Qiagen).  Reverse-transcribed products were then amplified using Kapa HiFi Hotstart PCR master mix (Kapa) and an IS PCR oligo primer (5' -AAGCAGTGGTATCAACGCAGAGT-3', IDT). Amplified double-stranded cDNA libraries were then purified using Agencourt Ampure XP beads (Beckman Coulter), followed by DNA concentration quantification using the Qubit dsDNA HS kit (Life Technologies).  0.2 ng of double-stranded cDNA was used in a tagmentation reaction using the Nextera XT DNA sample preparation kit (Illumina) per manufacturers protocol. Tagmented transcriptomes were then indexed using the Nextera XT 96-index kit for 384 samples (Illumina) per manufacturers instructions, and samples were then sequenced on a HiSeq 2500 sequencer (Illumina).
