Stent strut (black structure, a) surrounded by mostly spindle-shaped cells embedded in fiber-rich connective tissue (bare metal stent; Richardson blue staining); immunohistochemical staining (brown coloring) with antibodies against smooth muscle myosin (b; bare metal stent), vimentin (c; sirolimus-eluting stent), and smooth muscle actin (d; bare metal stent) identifying the spindle-shaped cells as fibromuscular cells; newly formed epithelium with polygonal cells lining the tracheo-bronchial lumen (e; bare metal stent; Richardson blue staining); cartilage structure within the newly formed tissue (f, arrows; sirolimus-eluting stent; Richardson blue staining)
