Firstly, the plasmid transfection technology will be used to introduce hBMP-2 gene into Hucb-MSC and chondrocytes, and its transfection efficiency will be determined through fluorescence microscopy observation. Then, real-time fluorescence quantitative PCR and Western Blot method will be used to detect the expression and protein content of hBMP-2 gene. Finally, the changes of chondrocytes and Hucb-MSC after transfection with hBMP-2 gene will be detected through cell proliferation, morphology, and cell skeleton experiments, exploring the proliferation, differentiation, and interaction between the two cells. This study will provide new ideas and experimental evidence for cartilage tissue engineering and stem cell research.Keywords: Human umbilical cord mesenchymal stem cells; chondrocytes; hBMP-2 gene; transfection; proliferation; differentiation; interaction.
