Fig. 7. Response of focal adhesions to Gd³⁺. IRM images of a NIH3T3 cell were recorded immediately before (A), or after the treatment with 100 µM Gd³⁺ at indicated time points (B,C). Note the transient increase in the darkness of the image (B, arrows), before the image returned to a pattern similar to that before the treatment (C). However, the adhesion plaques appeared less elongated compared with those before treatment, and more adhesion plaques were found near the center of the cell (C, arrows). Also there appeared to be some increase in the amorphous close contact compared to the image before treatment. Scale bar: 20 µm.
