Sample GSM2464261 Query DataSets for GSM2464261
Status Public on Dec 24, 2019
Title RNA_PD1_Pos_2
Sample type SRA
Source name PD-1+ non-LTi ILC progenitor
Organism Mus musculus
Characteristics strain: C57BL/6
cell type: PD-1+ non-LTi ILC progenitor
tissue: isolated from bone marrow
Extracted molecule polyA RNA
Extraction protocol Single cell suspension were obtained from the bone marrow of C57BL/6 mice. For sorting CLP and rChILP, the lineage negative cells were enriched with the "Lineage Cell Depletion Kit, mouse" from Miltenyi Biotec according to the manual. Enriched Lineage negative bone marrow cells were stained with relative antibodies followed by sorting on a cell sorter FACS Aria III (BD Biosciences) for "live Lineage-CD127+Flt-3+Integrin α4β7-Sca1+c-Kit+" CLP and "live Lineage-CD127+Flt-3-Integrin α4β7+T1/ST2-c-Κit+" rChILP. For sorting PD-1+ non-LTi ILC progenitors and CCR6+ LTi progenitors, the Fc receptor-blocked bone marrow single-cell suspension was stained with PE-conjugated anti-integrin α4β7 antibody, followed by washing and incubation with anti-PE microbeads. The samples were then applied to the Miltenyi LS columns in magnetic field and washed three times by PBS with 3% FBS according to the manufacturer’s instruction. The integrin α4β7+ cells on the column were finally flushed into a collection tube for further surface molecule staining. Non-LTi ILC progenitors (live Lineage-CD127+Flt-3-Integrin α4β7+T1/ST2-c-Κit+PD-1+CCR6-) and LTi progenitors (live Lineage-CD127+Flt-3-Integrin α4β7+T1/ST2-c-Κit+PD-1-CCR6+) were then sorted via FACS Aria III (BD Biosciences). CLPs, total rChILPs, PD-1+ or CCR6+ progenitors described above were sorted directly into 700 μL of QIAzol Lysis Reagent in the miRNAeasy Micro Kit (QIAGEN, Cat#217084). Total RNA was extracted and RNA-Seq libraries were prepared through the Smart-seq2 method (PMID: 24385147) as previously described (PMID: 29466755). Multiplex sequencing reads of 50 bp were generated by the NHLBI DNA Sequencing and Computational Biology Core.
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 3000
Data processing Basecalls performed using CASAVA 1.8.4
Sequence reads were mapped to the mouse (mm9) genomes with bowtie2 (2.2.2) with default settings. We kept one hit if multiple reads were mapped to the same position for each RNA-Seq libraries.
For each RNA-Seq sample, gene expression was quantified by RPKM with in-house script and RefSeq gene annotation.
