Fig. 9. Quantitation of FN fibril growth on conditioned substratum. Substratum was conditioned with stage 9 blastocoel roofs for varying times. For isolated patches of fibrils corresponding to single cells, total fibril length, i.e. the sum of the lengths of all individual fibrils, and fibril number were determined. Dots were not counted as fibrils. For each time point, those three patches with the largest total fibril length, or the highest number of fibrils, were selected, and averages were calculated as for Fig. 7a. Vertical bars represent the range between the highest and the lowest value, as in Fig. 7a, not standard deviations. The average increase in total fibril length per cell (L) during the first 5 minutes is 18 mm/min, the average increase in fibril number (n) is 10 fibrils/min. The growth of single fibrils (Fig. 7a) is shown for comparison (l, broken line). Image published in: Winklbauer R and Stoltz C (1995) Copyright © 1995.
