Figure 5From: Lipopolysaccharide induces nitric oxide synthase expression and platelet-activating factor increases nitric oxide production in human fetal membranes in cultureMean concentrations of NO2- in medium of human fetal membrane discs cultured for 24 h with serum under control conditions and in the presence of PAF (1 μM). Mean + SEM (n = 3). All of the fetal membrane samples were initially negative for iNOS mRNA, as detected by the standard RT-PCR method.Back to article page
