Sample GSM3142406 Query DataSets for GSM3142406
Status Public on Feb 25, 2021
Title OCP_BOTH_3_run1: OCP_RNASeq - Osteoclast_precursors Combined_treatment replicate_3 run_1
Sample type SRA
Source name Osteoclast precursors
Organism Mus musculus
Characteristics strain: C57BL/6
age: 6-7 weeks
tissue: Osteoclast precursors
treatment: ZA & G-CSF
biological replicate: 3
sequencing batch: 1
Treatment protocol Zoledronic acid (ZA) [1-hydroxy-2-(1H-imidazole-1-yl)ethylidene-bisphosphonic acid] (Novartis Pharmaceuticals, Cambridge, MA) was dissolved in 1X Hank’s Balanced Buffer Solution (Gibco) and stored at 4°C until use. ZA was administered to mice at a dose of 100 µg/kg (i.p.). Recombinant human granulocyte colony stimulating factor (G-CSF) (carrier-free, Biolegend #578604) was administered to nude mice each day for 3 days at a dose of 50 µg/kg (i.p.) beginning one day after administration of ZA, and C57BL/6 mice each day for 3 days at a dose of 50 µg/kg (i.p.) beginning 2 days after administration of ZA. For G-CSF depletion experiments, nude mice were treated with 100 µg/kg (i.p.) G-CSF antibody (R&D Systems, MAB414100) or the 100 µg/kg (i.p.) isotype control IgG (R&D Systems, MAB005) six hours prior to intracardiac injection of tumor cells.
Growth protocol 6-7 week old C57BL/6J female mice were purchased from The Jackson Laboratory (Bar Harbor, ME). All animal procedures were performed in accordance with the ethics and regulations of Brigham & Women’s Hospital Institutional Animal Care and Use Committee (protocol approval 2017N000056), Boston Children’s Hospital Institutional Animal Care and Use Committee (protocol approval 12-11-2308R), and Massachusetts General Hospital (protocol approval 2017N000023).
Extracted molecule total RNA
Extraction protocol RNA isolated from mouse bone marrow was subject to quality control using the Bioanalyzer (Agilent). BMCs were prepared for flow cytometry by suspension in sterile PBS containing 2% FBS. Cells were labeled with appropriate antibodies for 30 minutes at 4°C. Gating was used to exclude debris, cell clumps, and dead cells (using 7-aminoactinomycin D; 7-AAD Viability Staining Solution (BioLegend, 420404).Prior to sorting of the M/OCP populations, the Murine Direct Lineage Cell Depletion Kit (Miltenyi Biotec Inc., 130-110-470) was used to enrich for Lin- populations, which was confirmed by flow cytometry for the markers in the lineage cocktail. Myeloid/osteoclast progenitor cell (M/OCP) populations were defined as Lineage- CD115+. Antibody panel includes: Pacific BlueTM anti-mouse Lineage Cocktail (BioLegend, 133310: CD3-, Ly-6G/Ly6-C-, Cd11b-, CD45R-, TER119-) and Alexa Fluor® 488 anti-mouse CD115 (CSF-1R; BioLegend, 135511).
RNA was converted into a DNA library using the Ultra RNA Library Prep Kit for Illumina (New England BioLabs). After further quality control, libraries were sequenced on the HiSeq 2000 (Illumina).
