Figure 8From: Regional expression of HOXA4 along the aorta and its potential role in human abdominal aortic aneurysmsLocalization of HOXA4 protein in cultured human aortic ECs (A) and SMCs (B) using immunofluorescence. The cells were stimulated for 1 or 18 hours using 50 ng/ml IFN-γ. Green, staining with anti-HOXA4 antibody; and Red, F-actin filaments stained with phalloidin. Scale bar = 20 μm.
