Abstract
Introduction: Cartilage injury is the most common injury among orthopedic diseases. The predominant treatment for this condition is cartilage transplantation. Therefore, production of cartilage for treatment is an important strategy in regenerative medicine of cartilage to provide surgeons with an additional option for treatment of cartilage defects. This study aimed to produce in vitro engineered cartilage tissue by culturing and differentiating umbilical cord derived mesenchymal stem cells on biodegradable Poly(ε-caprolactone) (PCL) scaffold.
Methods: Human umbilical cord derived mesenchymal stem cells (UCMSCs) were isolated and expanded according to previous published protocols. UCMSCs were labeled with CD90 APC‑conjugated monoclonal antibody (CD90-APC) and then seeded onto porous PCL scaffolds. Cell adhesion and proliferation on PCL scaffolds were evaluated based on the strength/signal of APC, MTT assays, and scanning electron microscopy (SEM). The chondrogenic differentiation of UCMSCs on scaffolds was detected by Alcian Blue and Safranin O staining.
Results: The results showed that UCMSCs successfully adhered, proliferated and differentiated into chondroblasts and chondrocytes on PCL scaffolds. The chondrocyte scaffolds were positive for some markers of cartilage, as indicated by Alcian Blue and Safranin O staining.
Conclusion: In conclusion, this study showed successful production of cartilage tissues from UCMSCs on PCL scaffolds.
