Question

I got this question in an exam :
How does the extracellular matrix interact with cells :
a) with proteoglycans
b) with collagen
c) with fibronectins
d) with tight junctions
I answered a because the proteoglycans constitute the network that holds the cells and extracellular proteins. I ruled out fibronectins because they form a dimer with integrins to connect collagen and the cell, which is just an example of an interaction. But proteoglycans are the fibres which collagen is embedded in and which support the interactions in general. Am I wrong? Thanks in advance.
