Genome-wide RNA sequencing of sequential TLR agonist stimulation in C57Bl6/J macrophages

We report the genome-wide RNA sequencing of bone marrow derived macrophages after sequential TLR agonist stimulation. Overall design: Examination of sequential TLR agonist stimulation. Bone marrow derived macrophages (BMDMs) were prepared from male animals 6-12 weeks of age. Cells were isolated from femurs and tibias. The bone marrow cells were and grown in macrophage growth medium (RPMI 1640 supplemented with 10% FBS (Gibco), 1% penicillin-streptomycin (Gibco), 2 mM L-glutamine (Gibco), 1 mM sodium pyruvate (Gibco), 0.01 M HEPES (AmericanBio), and 30% L929-conditioned media as a source of CSF-1), and plated on petri dishes. Macrophage growth medium was supplemented on day 3. Cells were plated for use on day 6. For sequential stimuli, cells were first stimulated with, PBS, 100 ng/mL Poly I:C (InvivoGen), or 5 ng/mL LPS derived from Escherichia coli 055:B5 (Sigma-Aldrich). 24 hours after the initial stimulation, the media was removed and cells were washed twice with warmed macrophage growth media, and then the media was replaced with Poly I:C or LPS.
