Gross morphological observation of articular cartilage in the knees of the rat, Magnification: X10. A) The gross appearance of control group with smooth surface with no osteophytes or erosions, B) The osteoarthritis group: erosion was observed in joint surface, C) The ASC group. Partial regeneration of erosion in articular surface compared with OA group, D) Chondron group. Regeneration of erosion in articular surface compared with OA group, E) Co-culture of chondron and ASC group: Smooth articular surface with no erosions.
