| Growth protocol |
Two independently derived mouse ES cell lines were used in this study: IB10 ESCs (129/Ola background) and 129/Cast ESCs (129SVJ/Casteneus background). IB10 ESCs were grown in BRL conditioned DMEM (high glucose, Gibco) supplemented with 15% FBS, 1X NEAA (Gibco), 1X Pen Strep (Gibco), 1:1000 β-mercaptoethanol (Invitrogen), 1X L-Glutamine (Gibco) and 1000 U/ml LIF (Gibco). 129/Cast ESCs were grown on irradiated mouse embryonic fibroblasts (MEFs) in DMEM supplemented with 15% FBS, 1x NEAA, 1x Pen Strep, 1:1000 β-mercaptoethanol and 1000 U/ml LIF. NP cells (IB10 and 129/Cast) were grown in DMEM-F12 supplemented with 1:100 N2 (Gibco), 20 ng/ml bFGF (Peprotech), 20 ng/ml murine EGF (Peprotech). For the 129/Cast NP cells, 1X B-27 (Gibco) was added. We generated astrocytes by growing IB10 NP cells to confluency and washing twice with DMEM before adding astrocyte medium (DMEM-F12 supplemented with 1:100 N2 and 2% FBS). The culture medium was changed twice and cells were grown for 5 days to make sure differentiation was complete, which was confirmed by immunofluorescence.
NPCs were generated according to Conti and colleagues (Conti et al. 2005) with slight modifications. In brief, ES cells (129SVJ/CAST) were differentiated in N2B27 (StemCell Resources) for 7 days, followed by the formation of neural spheres in N2B27 supplemented with EGF and FGF (10ng/ml). 3-day-old spheres were allowed to attach to the culture dish to expand NPCs (also see Splinter et al., 2011, Genes & Development).

| Extraction protocol |
The initial steps of the 4C procedure, as published before (Simonis et al., 2006, Nature Genetics (PMID 17033623)), remain unchanged. Cells are cross-linked using 2% formaldehyde for 10min at room temperature in PBS 10%FCS and nuclei are isolated, after which chromatin is digested with HindIII and subsequently ligated under diluted conditions. After reversal of the cross-links, the DNA is purified and treated with the second restriction enzyme treatment (indicated in the sample description). After a second re-ligation step, the sample is purified and a 4C PCR is applied.

| Description |
4C PCR product.
Barcode: GGAGTGTACCAGCAAGCTT
|
| Data processing |
Library strategy: 4C-seq
The initial step in the 4C-seq analysis is the alignment of the sequencing reads to a reduced genome of sequences that flank HindIII sites (fragment ends), using custom Perl scripts. Due to their ambiguous nature in reporting contacts, repetitive fragment ends were excluded from subsequent analysis. The reduced genome was based on mouse genome mm9.
