| Source name |
forebrain neural progenitors

| Organism |
Homo sapiens |
| Characteristics |
time point: day_14
cell type: iPSC-derived forebrain neural progenitors
|
| Growth protocol |
iPS cells were differentiated into forebrain neural progenitor cells using the following protocol: The iPSCs were plated at 10.000 cells/cm2 in N2 medium (1:1 DMEM/F-12 (Gibco) and Neurobasal (Gibco) supplemented with 1% N2 (Gibco), 2 mM L-glutamine (Gibco), 0.2% penicillin/streptomycin (Gibco)) with dual SMAD-inhibition (10 µM SB431542 (Axon), 100 ng/ml noggin (Miltenyi)) as well as ROCK inhibitor (10 µM Y27632) on LN111 coated Nunc delta surface multidishes (1.14 µg/cm2; Biolamina). The media was changed every 2-3 days to N2 medium with SMAD-inhibitors up until day 9 of differentiation when only N2 medium was used. On day 11 the cells were dissociated using StemPro accutase (75 µl/cm2; Gibco) and replated at 800,000 cells/cm2 on LN111-coated Nunc plates in B27 medium (Neurobasal supplemented with 1% B28 without vitamin A (Gibco), 2 mM L-glutamine and 0.2% penicillin/streptomycin) supplemented with 10 µM ROCK inhibitor, BDNF (20 ng/ml; R&D), and L-ascorbic acid (0.2mM; Sigma-Aldrich). The cells were then harvested at day 13, 14, 15, or 16.

| Data processing |
bcl2fastq (Illumina) was used for base-calling.
The reads were aligned to the genome (GRCh38 and PanTro6) using STAR aligner v2.5.0a, allowing for 0.03 mismatches per base and multimapping at up to 10 loci.
The Subread package FeatureCounts was used to quantify the reads overlapping Gencode v27 gene annotations. The human Gencode annotation was lifted over to PanTro6 using UCSC LiftOver tool.
