parallel analysis of corresponding interference reflection micrographs showed that differences in the area of cell surface within 10-15 nm of the substratum correlated closely with each of the changes in adhesion observed : after incubation for 15 min on fibronectin at 37 degrees c , glioma cells increased their surface area within close contact to the substrate by integral to 125-fold .
