This study investigated the safety evaluation of intravenous infusion of human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) and found that the process was safe and vital signs were stable, but there was a slight decrease in blood pressure during infusion.
Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs), a kind of adult stem cell, were studied for clinical applications in regenerative medicine. To date, the safety evaluations of intravenous infusion of allogeneic hUC-MSCs were focused on fever, infection, malignancy, and death. However, the characteristics of dynamical changes in vital signs during hUC-MSCs infusion are largely unknown. In this study, twenty participants with allogeneic hUC-MSCs transplanted (MSC group) and twenty sex- and age-matched individuals with cardiovascular disease who treated with the equal volume of 0.9% normal saline were recruited (NS group). Heart rate, respiratory rate, oxygen saturation, systolic and diastolic blood pressure, and temperature were monitored at intervals of 15 min during infusion. Adverse events were recorded during infusion and within seven days after infusion. No adverse events were observed during and after infusion in both groups. Compared with the baseline, the mean systolic blood pressure (SBP) levels were significantly decreased at 15 min, 30 min, 45 min and 60 min in the MSC group (all P < 0.05) during infusion. In addition, SBP changed significantly from baseline during hUC-MSCs infusion when compared with that of NS group (P < 0.05). Repeated measures analysis of variance confirmed difference over time on the SBP levels (P < 0.05). Our results showed that the process of allogeneic hUCMSCs intravenous infusion was safe and the vital signs were stable, whereas a slight decrease in SBP was observed.& COPY; 2023, The Japanese Society for Regenerative Medicine.
