Histopathological Changes of Applying Nano-Fat on Articular Cartilage Degenerative Defect in A Dog Model

Damage to articular cartilage can ultimately lead to osteoarthritis, a debilitating degenerative joint disease. Treating cartilage damage is difficult because cartilage has a limited ability to heal itself and because currently available treatments are limited. Nano-fat tissue, a specific type of adipose tissue, comprises the greatest concentration of MSCs, fibroblasts, and pericytes. This study was conducted to evaluate the efficacy of Nano-fat on healing of articular cartilage in dogs. Methods Ten healthy adult mongrel dogs were used in current study, The dogs were divided into two equal groups (n = 5), Group I (the control group) was left without treatment. While group II (the nano-fat group) was treated by the application of nano-fat.Result, showed that the signs of mineralization occur in the peripheral portion, particularly in the edges near the trochlear groove of joint, while operation site of control group was filled with collagen fibres, and newly generated blood vessels are evident and numerous. Control group was not featuring cartilage regeneration Conclusion, Nano-fat used as a treatment can effectively enhance articular cartilage regeneration, enhance the newly generated blood vessels and accelerate the inflammatory process.
