Abstract
We analyzed the influence of initial properties of biopolymer fi lm extracellular matrices made of chitosan on adhesion of swine embryonic kidney epithelium-like cells, their morphology, growth, and proliferation. It was found that adhesion index of cells on the studied matrices was similar, but cell morphology had significant qualitative differences. Round non-flattened cells were described in endothelial cell cultures on chitosan-based matrices. Local variations in charge density on matrices induced by the presence of chitin nanofibers led to the appearance of flattened spindle-shaped and non-flattened sphericalal cells. Long-term culturing on biopolymer extracellular fi lm matrices was associated by the formation of spatial conglomerates of sphericalal cells.
