Hoxa3-lacZ reporter expression in mouse adult blood vessels
Hox transcriptional regulators are critical for early embryonic patterning and may play a role in specifying positional identities in the cardiovascular system. In transgenic Hoxa3-lacZ mice, X-Gal staining reveals Hoxa3-reporter gene expression in vascular smooth muscle cells in the aortic arch of adult mice (blue).
