Fig. 2. Dissociation of blastula stage animal caps causes a reduction in the
density of cortical actin, which is rescued by reaggregation of the cells.
(A,B) Low-(A) and high-(B) magnification images of the F-actin network in situ
in caps before disaggregation. (C) The coarser F-actin network found in single
cells 45 minutes after dissociation. (D) Reassociation of the animal cap cells
caused the cortical actin network to return to normal levels. Scale bars: 20
µm in A; 5 µm in B-D.
