A cell biologist is studying the migration of fibroblasts on substrates coated with different ECM proteins. On fibronectin-coated surfaces, cells migrate normally, but on vitronectin-coated surfaces, the same cells show impaired migration despite forming focal adhesions. What is the most likely explanation for this difference in migration efficiency?
