In Vivo Articular Cartilage Regeneration Using Human Dental Pulp Stem Cells Cultured in an Alginate Scaffold: A Preliminary Study
Figure 1
Osteochondral defects of 3 mm were generated in the knees of rabbits (a) and covered with alginate alone (b, e), alginate containing 2 × 106 rabbit primary chondrocytes (c, f), or alginate containing 2 × 106 hDPSCs (d, g). The animals were sacrificed 3 months after surgery. Representative macroscopic images of the animals () are shown.
