To determine whether an inflammatory signal without associated thrombocytopenia increased lung Mk production, we treated mice with IFN-γ and observed no change in total or CFSE+ lung-derived platelets (Figure 4B), indicating that platelet production in the lung was not changed in the setting of immune stimuli without concomitant thrombocytopenia. This evidence concerns the gene IFNG and Thrombocytopenia.
