Upregulation of Plasminogen Activator Inhibitor-1 in Irradiated Recipient Arteries and Veins from Free Tissue Transfer Reconstruction in Cancer Patients

Figure 8

Double-labelling of PAI-1 (red) and α-SMA (green) in an irradiated vein. Arrowheads indicate colocalization of PAI-1 and α-SMA, indicating expression of PAI-1 in myofibroblasts. Arrows indicate cells with PAI-1 expression but no α-SMA expression. Nuclear stain (DAPI) is shown in blue (scale bar = 50 μm).
