tissue: bone marrow cell type: macrophages genotype: WT
Treatment protocol
BMDM that had been exposed only to standard culture medium for 7 days were designated as M0, and basal expression levels were determined using RNA from these cells. For post-infection transcriptional analysis, M0 cells were exposed to P. aeruginosa strain K at an MOI of 5:1 for 1 h, after which infection media was aspirated, and cells were rinsed twice with PBS. The cells were then cultured in medium containing 75 μg/ml gentamicin, 100 IU/ml penicillin, and 100 μg/ml streptomycin, until RNA was collected at 6 h or 24 h after the end of the infection period.
Growth protocol
Bone marrow cells were differentiated to macrophages by 7 days of culture in RPMI media supplemented with 10% FBS and 20% conditioned media from L929 cells.
