| Outline of Final Research Achievements |
Treatments for neonatal hypoxic ischemic encephalopathy have been limited. Mesenchymal stem cells (MSCs) have significant potential for use in cell therapy for various diseases, through their ability to home to sites of injury, suppress immune responses, and undergo self-renewal and differentiation. The objective of this study is to characterize the gestational age-dependent change in MSCs from fetal tissues and to assess whether the MSCs could be useful for neonatal brain injury due to hypoxia or ischemia. First, we isolated umbilical cord-derived MSCs(UC-MSCs) from infants delivered at 22 to 40 weeks gestational age. UC-MSCs from preterm infants showed high proliferative capacity with increased levels of Wnt signaling pathway gene expression compared with those from term infants. Second, the lung injuries on rat model of bleomycin-induced hypoxemia and pulmonary fibrosis could be reduced by UC-MSCs, regardless of origin’s gestation.
