Final answer:
A fibroblast can attach indirectly to collagen through specialized proteins for cell adhesion, such as fibronectin and laminin.
Step-by-step explanation:
A fibroblast can attach indirectly to collagen through specialized proteins for cell adhesion, such as fibronectin and laminin.
These proteins form a connection between the fibroblast and the collagen fibers in the extracellular matrix (ECM).
Fibronectin is involved in cell migration and adhesion, while laminin is a major protein component of various basal laminas, including those found in renal glomeruli.
