Figure 4From: PlGF mediates neutrophil elastase-induced airway epithelial cell apoptosis and emphysemaPlGF triggers LE cell apoptosis via JNK and PKCδ signaling pathways. The PlGF-induced apoptosis was evaluated by (A) annexin V-FITC stained cells in flow cytometry assay and (B) fluorescent cells in terminal deoxynucleotidyl transferase dUTP nick end label (TUNEL) assay. Scale bar = 100 μm.Back to article page
