Figure 6.
Proliferation of human Chondrocytes cultivated in chitosan flock scaffolds (CFS), alginate hydrogels (ALG), and chitosan/alginate flock scaffolds (CFS+ALG). Cells were seeded directly onto the CFS or within the alginate gel with a density of 4 × 106/mL. Cell numbers were calculated from cytosolic LDH activities after 21 days of cultivation after cell lysis and are presented here relative to the cell number on day 1 after seeding. Mean ± SD, n = 3. p-value **** < 0.0001, *** 0.0001–0.001.
