| Growth protocol |
iPSC were differentiated for 24 days with initial neuralization with SB431542 (10 μM, Sigma Aldrich) and Dorsomorphin (1 μM, Stemgent), and motor neuron patterning with retinoic acid (1 μM, Sigma) and a small smoothened Agonist 1.3 (1 μM, Calbiochem). Differentiated motor neuron were dissociated using accutase, then filtered with a 70 µm filter and motor neurons, subsequently, isolated by activated flow cell sorting using HB9::GFP expression. Motor neurons were plated in the presence of P0 mouse glial cells and were maintained in Neurobasal media, supplemented with N2 and B27 (Invitrogen), 10 ng/mL each of BDNF, GDNF, CNTF (R&D) and ascorbic acid (0.4 μg/ml, Sigma) and fed every 2-3 days.

| Extracted molecule |
polyA RNA |
| Extraction protocol |
Total RNA from single cells was purified using RNA-SPRI beads. Poly(A)+ mRNA was converted to cDNA and amplified.
Poly(A)+ mRNA was converted to cDNA and amplified. cDNA was subjected to transposon-based fragmentation using dual-indexing to barcode each transcript fragment with a combination of barcodes specific to a single cell. Barcoded cDNA fragments were then pooled for sequencing.

| Data processing |
The data was demultiplexed and aligned to the human genome (hg19) using Tophat version 2.0.10
Transcripts were quantified by the BTL computational pipeline using Cuffquant version 2.2.1
Raw counts of reads mapped per gene were extracted from aligned bam Feature Counts (subread-1.5.0-p1)
Genome_build: hg19
Supplementary_files_format_and_content: read count table, fpkm table, run information, sample table
