2 Fig. 1 Composite photomicrograph demonstrating immunofluorescent images of monoclonal anti-α-smooth muscle actin antibody (passage 3). Extent of labeling to leading edge of cell is evident in A (open arrows). Most filaments are running along long axis of cells in B (solid arrow). Note also no nuclear staining. Magnification ×200.

4 Fig. 2 Composite electron micrograph of tibial smooth muscle cells in culture showing three phenotypes seen: A, contractile state (passage 3); B, intermediate state (passage 5); C, synthetic state (passage 7). In A, note extent of microfilaments (MF) throughout cytoplasm and highly irregular nuclear shape (N). Solid arrowheads denote dense plaques periodicity along MF. In B there is increase in number of ribosomes and polyribosomes (R). In later passage (C) there is disappearance of MF. LYS, Secondary lysosomes; LP, neural lipids. Magnification (A) ×4, 150, (B) ×3, 500, (C) ×5, 100.
