Abstract (original English)

We analyzed the suitability of various collagen-based scaffolds for culturing and osteogenic differentiation of mesenchymal stromal cells (MSC). Decellularized and lyophilized swine intestinal submucosa (SIS) and porous collagen sponge made from reconstructed bovine derma (PCS) were the most effective in promoting MSC adhesion, survival, and growth. MSC from rat and mouse bone marrow and rat adipose tissue successfully adhered to the scaffold surface and penetrated into its deep layers. These scaffolds were also the most effective in inducing osteogenesis. These results indicate that microarchitectonics of PCS and SIS is optimal for support of MSC growth and osteogenic differentiation.
