Abstract (original English)
Tissue engineering (TE) strategies aim at imitating the natural process of regeneration by using bioresorbable scaffolds that support cellular attachment, migration, proliferation, and differentiation. Based on the idea of combining a fully degradable polymer [poly(ɛ-caprolactone)] with a thermoresponsive polymer (polyethylene glycol methacrylate), a scaffold was developed, which liquefies below 20°C and solidifies at 37°C. In this study, this scaffold was evaluated for its ability to support C2C12 cells and human adipose-derived stem cells (ASCs) to generate an expandable three-dimensional (3D) construct for soft or bone TE. As a first step, biomaterial seeding was optimized and cellular attachment, survival, distribution, and persistence within the 3D material were characterized. C2C12 cells were differentiated toward the osteogenic as well as myogenic lineage, while ASCs were cultured in control, adipogenic, or osteogenic differentiation media. Differentiation was examined using quantitative real-time PCR for the expression of osteogenic, myogenic, and adipogenic markers and by enzyme activity and immunoassays. Both cell types attached and were found evenly distributed within the material. C2C12 cells and ASCs demonstrated the potential to differentiate in all tested lineages under 2D conditions. Under 3D osteogenic conditions for C2C12 cells, only osteocalcin expression (fo
