The contrary is apparently true.

We are building neighborhoods of an incredible number of cells within an environment that resembles the center.’ Cardiomyocytes fare better if they are surrounded by other cell types and also have something to carry to. They make use of proteins on the surface known as integrins to contact, adhere to and talk to their environment. Farndale provides perfected a ‘toolkit’ that pinpoints specifically which elements of collagen the integrins bind greatest; then makes complementing peptide fragments to ‘decorate’ the collagen scaffold. Thus giving cells a foothold in the scaffold and motivates different cell types to go in and populate the framework.
