Fig. 4. Addition of a piece of ECM material to the end of a fibril. Time-lapse image series showing the addition of a small piece of ECM material (arrowhead) onto a Y-shaped fibril (arrow). Note that this piece of fibrillar material is gradually moved upward and added on to the end of the Y-shaped fibril (Bar=25 µm). A movie showing this addition event and the associated cell movement is available as Movie 4 in supplementary material.
