Fig. 5. Attachment and detachment of cells on fibronectin. (A) Cells were seeded on fibronectin-coated wells and the percentage of bound cells was quantified by the adhesion assay described in the Materials and Methods. (B) Cells were seeded on fibronectin-coated slides and then subjected to a dislodging shear stress of 250 dyn/cm². The percentage of detached cells was quantified. Bars represent mean±s.d. of three separate experiments.
