Figure 6 Histological images of cartilage tissue of knee joints of each group. The collagen II staining was strongest in the sham surgery group, weakest in the model control group, weakest in matrix metalloproteinase-1 and matrix metalloproteinase-13 staining in the sham surgery group (blank control group), and strongest in the model control group. MMP: Matrix metalloproteinase; N-hUCMSCs: Serum-free human umbilical cord mesenchymal stems; S-hUCMSCs: Serum-cultured human umbilical cord mesenchymal stem cells.
