Outline of Final Research Achievements |
The ultimate goal of this study is to examine the protective effect of umbilical cord-derived MSCs for neonatal sepsis using preterm sepsis mouse model.
The research results to date have not proved the sepsis-protective effect of MSCs administration in the adult sepsis mouse model. Whereas, we have succeeded in establishing an experimental system of oxidative stress dynamics using urine samples of sepsis model mice, and a drug treatment experimental system for preterm sepsis mouse model. Thus, we will verify the protective effect of MSCs by using these protocols in future research.

Academic Significance and Societal Importance of the Research Achievements |
新生児敗血症、全身性炎症反応に加えて、酸化ストレスなどの複数の侵襲因子が関与し、従来の抗菌薬治療単独では十分な治療効果が得られていない。 一方、間葉系幹細胞(Mesenchymal Stem Cells、以下MSCs)は傷害組織に集積し、種々の因子を放出して治療効果を発揮する点において、多臓器不全を本態とする早産児敗血症の理想的な治療法といえる。本研究では、ヒト臍帯から分離・培養したMSCsを、我々が独自に確立した早産児マウス敗血症モデルに投与し治療効果を検討した。
