Figure 1
(a, b) Immunofluorescent staining and quantitative analysis of SDF-1 in subchondral bone shows SDF-1 significantly elevates in the ACLT groups. Scale bar, 50 μm. (c) Representative three-dimensional micro-CT images of sagittal views of the tibia subchondral bone medial compartment. (d–g) 3D parameter analysis of the tibia subchondral bone. (h, i) Safranin O and fast green staining shows proteoglycan loss and cartilage degeneration and the OARSI score for each group. Scale bar, 50 μm. (j) H&E staining shows calcified cartilage (CC) and hyaline cartilage (HC) thickness marked by double-headed arrows. Scale bars, 50 μm. (k) Quantitative analysis of CC and HC ratio in each group. , , and .
