|
Source name |
Lineage–Sca1+cKit+CD34–Flk2– long-term hematopoietic stem cells
|
Organism |
Mus musculus |
Characteristics |
treatment: none strain: C57BL/6 cell type: long-term hematopoietic stem cell genotype: wild type
|
Treatment protocol |
Long-term hematopoietic stem cells were isolated from bone marow of WT or Twist1 cKO mice 12 days after irradiation treatment or under steady state
|
Extracted molecule |
total RNA |
Extraction protocol |
Lineage–Sca1+cKit+CD34–Flk2– cells were collected and RNA was harvested using RLT reagent. Qiagen RNeasy Mini Kit (Cat#74104) was used for the construction of sequencing libraries. For ATAC-seq samples nuclei were subjected to Tn5 transposase reaction (Illumina Nextera DNA Sample Preparation Kit) following manufacturer’s instructions and DNA was purified using the Agencourt AMPure XP beads (Beckman Coulter). RNA libraries were prepared for sequencing using standard Illumina protocols. ATAC-seq was performed as originally described in Buenrostro et al. 2013.

Data processing |
RNA-seq: Illumina Casava1.7 software used for basecalling. RNA-seq: Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence,then use BWA (Li, H. and Durbin, R., 2009) to map clean reads to genome reference and use Bowtie (Langmead B, et al., 2009) to gene reference. ATAC-seq: skewer 0.1.126 is required for trimming raw data. Parameter: -m pe. ATAC-seq: BWA 0.7.12-r1039 is required for mapping. Parameter: -T 25 -k 18. ATAC-seq: deepTools3.0.2 is required for sample analysis. Parameter: --corMethod pearson. ATAC-seq: MACS2 2.1.0 is required for peak calling. Parameter: -q 0.05 --nomode --call-summits --nomodel. ATAC-seq: homer findMotifsGenome.pl v4.9.1 is required for identifying motif. Parameter: -gc -len 8,10,12,14. Genome_build: mm10 Supplementary_files_format_and_content: RNA-seq: Gene quantification txt file; ATAC-seq: Signal track bigWig file.
