LPS induces GM-CSF, G-CSF, LIF, and IL-6 mRNAs in bone marrow stromal cells. BMS2 (bone marrow stromal) cells were cultured in the presence of 1 μg/ml LPS for eight hours. Cells were harvested, RNA was extracted, and mRNAs specific for several cytokines were assayed by RNAse protection assays (RPAs). Representative data from two experiments (seven total) are presented.
