Abstract: | Studies of spreading fibroblasts and glial cells showed that the initial phase of the spreading process on a solid substratum proceeds by sequential development of different kinds of protrusions. Initially there is a high blebbing activity which is followed by development of small lamellipodia and somewhat later microspikes are formed. In the periphery of the spreading cells several types of microfilament organizations are displayed, these seem to be related to different stages in the cycles of extensions and retractions performed by the lamellipodia. The presence of microtubules and their relation to the different microfilament organizations are also shown. |
