The use of protein hydroxy ethylmethacrylate (HEMA) hydrogels to control cell morphology and growth, as well as the synthesis of extracellular matrix components, is described in this communication. HEMA hydrogels prepared with collagen support growth of embryonic lung fibroblasts (IMR-90), as well as bovine aortic and pulmonary artery endothelial cells at a level comparable to the respective cells grown on tissue culture surfaces. On the other hand, HEMA hydrogels prepared with solubilized elastin inhibit the fibroblast growth and prevent both types of endothelial cell cultures from achieving their normal morphology. These morphologically altered endothelial cells resume a normal cobblestone-like appearance when subcultivated from the elastin-HEMA hydrogels to tissue culture plastic. When pulsed with [14C]proline, the procollagens synthesized by the endothelial cells on the different surfaces vary, as shown by immunoprecipitation and polyacrylamide gel electrophoresis. On the standard tissue culture plastic, the confluent cells produce mainly type III procollagen in the medium, whereas those endothelial cells grown on collagen and elastin-HEMA hydrogels synthesize primarily type I procollagen (much like sprouting cells on tissue culture plastic), regardless of their morphology.
