Fig. 6From: Mass spectrometry imaging as a tool for evaluating the pulmonary distribution of exogenous surfactant in premature lambsa Reconstructed spatial distribution images of the SP-B analog in the lungs of surfactant-treated (SF) and untreated control (C) animals. b Boxplots showing the difference of MSI-derived parameters (the log10 average intensity of ion inside the lung tissue section, Avg_log10_I; and the absolute signal of the ion in the lung section from those pixels with a signal above the noise level, Σ_log10_I) in control (Ctrl) and surfactant-treated animalsBack to article page
