Fig. 6. Localization of FN oligomers over actin fibers. Cells were treated for 5
minutes with different FN-TN constructs and then fixed and labeled
simultaneously with avidin to localize the FN-TN, and with phalloidin to
localize actin polymers. The FN-TN streaks produced by the trimer and pentamer
are always localized over actin fibers, but only a sub-set of the actin fibers
is decorated. The streaks of plasma FN were shorter and more peripheral than
those of FN-TN trimer and pentamer, and localized over shorter segments of
actin fibers.
