In higher vertebrates, smooth muscle (SM) contains two tissue-specific actin isoforms: α-SMA and γ-SMA, which predominate in vascular and visceral SM, respectively. Whether α-SMA has been extensively studied and recognized for its contractile activity in SM and SM-like cells such as myofibroblasts, myoepithelial and myoid cells, the distribution and role of γ-SMA remained largely unknown. We developed a new specific monoclonal antibody against γ-SMA and confirmed that γ-SMA predominates in the visceral system and is minor in the vascular system, although more expressed in highly compliant veins than in stiff arteries.
