I found this to be a very thorough reference across a broad range of extracellular matrix proteins. In particular, identifying which critical ECM proteins to add back to 3D cell culture conditions to re-approximate the in vivo milieu. It was highly touted at http://home.ease.lsoft.com/archives/3d-cell-biology.html and www.puramatrix.com as a key manual for research and bioproduction involving ECM proteins.
