Cobalt-containing calcium silicate nanowires incorporated scaffolds for the repair of osteochondral defect induced by chondrosarcoma
Source abstract
Abstract
Considering the difficulty in the treatment of chondrosarcoma in clinic, multifunctional composite hydrogel scaffolds were designed with excellent photothermal ability for the regeneration of damaged bone and cartilage tissue. The chitosan solution/polyvinyl alcohol (CP) hydrogels with different contents of cobalt doped calcium silicate (Co-CSH) nanowires were prepared via 3D printing method. Attributing to the excellent photothermal performance of Co-CSH nanowires, the average survival rate of human chondrosarcoma cells in the CP-5Co-13.4 % and CP-5Co-16.2 % scaffolds with near infrared laser irradiation was about 10.5 % and 9.9 %, respectively. At the same time, the prepared composite hydrogel scaffolds possessed satisfactory biocompatibility and could support the adhesion and spread of rabbit bone mesenchymal stem cells (rBMSCs) and rabbit chondrocytes in the hydrogel scaffolds, and further promoted the formation of new bone and cartilage tissue in vivo , on account of the stimulation effect of released bioactive ions. Therefore, the prepared composite hydrogel scaffolds is expected to provide a new therapeutic strategy for the postoperative adjuvant treatment of chondrosarcoma.
