摘要：

Extracorporeal membrane oxygenation (ECMO) is a well-known therapy for refractory cardiac and respiratory failure. Stem cell therapy has been investigated as an adjunctive treatment for use during ECMO, but little is known about the viability of stem cells during ECMO support. We evaluated the viability and activity of mesenchymal stem cells (MSCs) in ex vivo circulation (EVC) conditions. The experimental groups were divided into two subgroups: EVC with oxygenator (OXY group) and EVC without oxygenator (Non-OXY group). Mesenchymal stem cells (1.0 x 10(7)) were injected into the EVC system. Cell counting, a lactate dehydrogenase (LDH) cytotoxicity assay, and the mitochondrial functions of viable MSCs were analyzed. The post-EVC oxygen consumption rate (OCR) was significantly lower than the pre-EVC OCR, regardless of whether the oxygenator was used. The LDH levels were significantly higher in the OXY group than in the Non-OXY group. The cellular loss was mainly due to lysis of the cells whereas the loss of cellular activity was attributed to the nonphysiologic condition itself, as well as the oxygenator. We concluded that direct infusion of MSCs during ECMO support did not serve as adjunctive therapy. Further studies are needed to improve the viability in an ECMO setting.
