Human Cardiac Fibroblasts in Producing Cell-Derived Matrices

We reported a specialized protocol to produce human cardiac cell-derived matrices without the introduction of exogenous matrix proteins. Human cardiac fibroblasts cultured under conditions to produced cell-derived matrices were harvested at the beginning, middle and completion of the experiment - corresponding to days 0, 5 and 10. Fetal and adult human cardiac fibroblasts were cultured densely in the presence of ficoll as a macromolecular crowder on the adhesive biopolymer l-polydopamine, and sampled throughout matrix deposition to determine the age-specific responses of primary human cardiac fibroblasts to macromolecular crowders and enhanced matrix deposition. Analysis of sequential timpoints during culture of fetal and adult human cardiac fibroblasts with ficoll.
