To evaluate the biocompatibility, cell adhesion, proliferation, and phenotype preservation of rat chondrocytes cultured on a biodegradable polyesterurethane scaffold (DegraPol-foam).
Seeded primary chondrocytes isolated from xyphoids of adult male rats onto porous DegraPol-foam scaffolds and tissue culture polystyrene controls.
Assessed cell attachment, internal infiltration, and morphology using scanning electron microscopy.
Quantified cell proliferation kinetics, collagen type II to type I ratios, and chondroitin sulfate production over a 14-day culture period.
Chondrocytes adhered to DegraPol-foam at approximately 60% of the level observed on tissue culture polystyrene and exhibited a population doubling time of roughly 12.5 days.
Cells infiltrated the open pores, maintaining a rounded morphology and preserving their phenotype for 14 days, with collagen type II/I ratios 1.2- to 1.4-fold higher than freshly isolated cells.
Chondroitin sulfate production remained stable, with no significant differences observed between cells grown on DegraPol-foam for up to 14 days and freshly isolated chondrocytes.
