Endothelial differentiation of bone marrow mesenchyme stem cells applicable to hypoxia and increased migration through Akt and NFκB signals.

Background: Bone marrow mesenchymal stem cells (MSCs) and endothelial progenitor cells (EPCs) are used to repair hypoxic or ischemic tissue. However, the underlining mechanism of resistance in the hypoxic microenvironment and the efficacy of migration to the injured tissue are still unknown. The current study aims to understand the hypoxia resistance and migration ability of MSCs during differentiation toward endothelial lineages by biochemical and mechanical stimuli.

Facilitation of human osteoblast apoptosis by sulindac and indomethacin under hypoxic injury.

Hypoxic-ischemia injury occurs after trauma causes consequential bone necrosis. Non-steroid anti-inflammatory drugs (NSAIDs) are frequently used in orthopedic clinics for pain relief. However, the underlying mechanism and outcome for usage of NSAIDs is poorly understood.
