USP13 Overexpression in BMSCs Enhances Anti-Apoptotic Ability and Guards Against Methylprednisolone-Induced Osteonecrosis in Rats.
Methylprednisolone (MPS) use is linked to increased cases of osteonecrosis of the femoral head (ONFH). Bone marrow mesenchymal stem cells (BMSCs) have shown potential for treating MPS-induced ONFH, but their effectiveness is limited by high apoptosis rates post-transplantation. We developed a pre-treatment strategy for BMSCs to improve their viability. In a rat model of MPS-induced ONFH, we evaluated the effects of USP13 overexpression in BMSCs through micro-CT, HE staining, and TUNEL staining. USP13-overexpressing BMSCs significantly reduced ONFH severity compared to plain BMSCs and direct lentivirus injection. USP13 also protected BMSCs from MPS-induced apoptosis by modulating PTEN and reducing AKT phosphorylation. This led to decreased expression of apoptotic genes and proteins in USP13-overexpressing BMSCs. Our findings highlight USP13 as a promising target for enhancing BMSC survival and efficacy in treating MPS-induced ONFH.
