(a) N-cell cytoskeleton; (b-d) X-cell cy- toskeletons. N-cell MBs were typically ellipsoids, sometimes twisted into figure-8s. X-cell MBs were essentially intact, but assumed highly convo- luted shapes without apparent breakage. A diagram of the basic MB deformation pattern observed in many X-cells ( b. c) is given in (e); some twist patterns were more complex, however ( d). Fluorescence microscopy; bar = 10 ;um. activit

By 60 min, experimentals had 0%-15% X-cells, whereas controls still. Figure 10. Shape reversal in cells containing or lacking MBs. (a) MB-containing cells: only minor post-reversal surface deformations were observed; (b) cells lacking MBs; major surface indentations were retained post-reversal.
