Figure 2.

Immunolocalization of FABP4 and FABP5 in a baboon model of BPD. Representative images are shown. FABP4 was detected in macrophages in BPD, but not in control samples (first row, red arrowhead). FABP4 was also detected in peribronchial vascular endothelial cells in both control and BPD samples (second row, black arrowheads). FABP5 was localized to bronchiolar (third row, green arrowheads) and alveolar epithelial Type 2 cells (fourth row, red arrowheads), as well as macrophages (fourth row, black arrowhead). Scale bars = 50 μm.
