A cell can crawl through a tissue because of the transmembrane __________ proteins that can bind to fibronectin outside of the cell.

Question

Quizplus · Accepted Answer

This binding allows the cell to anchor to the extracellular matrix and exert a pulling force, which can enable it to crawl through the tissue.
