  • Many models are based on the fact that the actin polymerization is a major contributor to the protrusive force, which leads to the extension of the lamellipodia of crawling cells on a hard substrate.
  • In cells without a lamellipodium, the lamella reached all the way to the leading edge and the pattern of turnover did not deviate from its randomness, even in phases of pronounced protrusion.
  • In these motile cells, lamellipodia of various shape are continually extended in different directions.

Example sentences
  • Third, as far as the diffusion-limited growth is concerned, our estimates were made for the steadily protruding lamellipodial leading edge.
  • Kymographic analysis of EGF-stimulated lamellipodial dynamics revealed that the temporal stability of lamellipodial protrusions similarly increased with fibronectin concentration.
  • Another possible role of relatively rigid actin bundles embedded into the lamellipodial actin sheet is to strengthen the lamellipodium against buckling, by analogy with engineered macroscopic structures.
