Expression patterns of cytoskeletal proteins in cultured peribiliary myofibroblasts. Cultures of peribiliary myofibroblasts were established by outgrowth from bile duct segments and submitted to an avidin-biotin immunoperoxidase method. A, A homogeneous pattern of α-SMA expression. B, A heterogeneous pattern of desmin expression in subcultured cells (passage 3). Original magnification, × 400.
