Actomyosin organisation for adhesion, spreading, growth and movement in chick fibroblasts.


Examination of the actomyosin structures and their relation to adhesion, movement and growth in the first fibroblasts migrating from chick heart explants shows striking differences with fibroblasts adapted to grow in culture. The latter have focal adhesions which seem to immobilize them for anchorage-dependent growth, rather than facilitate their movement. The fibroblasts specialized for movement from the explants, though equally well spread, make contact with substratum through extensive areas of relatively unspecialized membrane, have less well developed stress fibres and a low growth rate.
