Effects of Focused Extracorporeal Shock Waves on Bone Marrow Mesenchymal Stem Cells in Patients with Avascular Necrosis of the Femoral Head.

To observe the effect of extracorporeal shock waves (ESWs) on bone marrow mesenchymal stem cells (MSCs) in patients with avascular necrosis of the femoral head, we collected bone marrow donated by patients and then cultivated and passaged MSCs in vitro using density gradient centrifugation combined with adherence screening methods. The P3 generation MSCs were divided into the ESW group and the control group. The cell counting kit for MSCs detected some proliferation differences.

Liposomal short-chain C6 ceramide induces potent anti-osteosarcoma activity in vitro and in vivo.

Osteosarcoma (OS) remains one deadly disease for many affected patients. The search for novel and more efficient anti-OS agents is urgent. In the current study, we demonstrated that liposome-packed C6 ceramide exerted potent cytotoxic effect against established (U2OS and MG-63 lines) and primary human OS cells.
