摘要

The 1 1 and 2 1 integrins belong to a family of cell-surface molecules involved in structural contacts and signal-transduction events across the cell membrane. Employing two-dimensional substrates coated with fluorescently labeled type I collagen, we have discovered a novel subcellular matrix remodeling event that is particular to cells that express the fibrillar collagen receptor 2 1. Cells expressing 1 1 also perform this collagen organization process, but less proficiently. This work will provide a basis for subsequent studies of cell-mediated collagen fibril assembly.
