Chitosan crosslinked with glutaraldehyde or oxidised dextran was studied as a potential scaffold material in tissue engineering
for cartilage regeneration. By mixing two solutions of both components it became a gel, which was frozen. After lyophilisation
a scaffold was generated with interconnected pores with diameters ranging between 120–350 μm. The mechanical properties (yielding
point, elastic and viscous moduli), absolute porosity, pore morphology were determined depending on the ratio of chitosan
to crosslinker. ATDC5 (murine cell line) and bovine articular chondrocytes (primary cells) were cultured for 14 days on the
scaffolds. Cultivation with ATDC5 cells and bovine chondrocytes showed no negative influence of glutaraldehyde on cell vitality
and growth.
