 In this study, researchers developed a new nanomaterial called MIL-88A which can be used to treat osteoarthritis, OA. They found that MIL-88A can increase the expression of genes related to bone formation while decreasing those associated with cartilage breakdown. This suggests that it may be able to slow down or even reverse the progression of OA. Additionally, they observed that mice treated with MIL-88A had improved scores on an OA severity scale compared to untreated mice. These results suggest that MIL-88A may be a promising treatment option for OA.
