Fig. 10. Aggregate formation and compaction of CHO-A5 cells in the presence of RGD
peptide. CHO-A5 cells secrete low levels of endogenous FN. Culturing these
cells in FN-depleted medium resulted in formation of cellular sheets (A). With
the addition of 100 µM RGD peptide CHO-A5 cells failed to form aggregates
(B). Bar, 1.0 mm.
