TY - JOUR TI - Hypoxic Preconditioning of Human Umbilical Cord Mesenchymal Stem Cells Is an Effective Strategy for Treating Acute Lung Injury AU - Wang, Yujuan AU - Li, Han AU - Li, Xue AU - Su, Xin AU - Xiao, Han AU - Yang, Junling T2 - Stem Cells and Development AB - Acute respiratory distress syndrome (ARDS)/acute lung injury (ALI) is a severe clinical respiratory failure disorder associated with chronic pathology and disability and has a mortality rate of 40%–60%. However, the pathogenesis of ARDS/ALI remains unclear, and existing therapeutic options are insufficient for addressing the severity of the disease. Mesenchymal stem cells (MSCs) play an important role in the prevention and treatment of ALI, especially acute alveolar epithelial injury. However, the low survival rate of transplanted MSCs reduces their effectiveness. When human umbilical cord MSCs (hUC-MSCs) are transplanted directly, only a minority of cells migrate toward damaged tissues. Moreover, their maintenance time is short, leading to unsatisfactory therapeutic results. A moderate hypoxic environment can promote the proliferation of MSCs, inhibit apoptosis, and facilitate migration and chemotaxis. In summary, hypoxic culturing before transplantation improves the effectiveness of hUC-MSCs in treating ARDS/ALI and promises to provide novel diagnostic and therapeutic targets.
