| Outline of Final Research Achievements |
We investigated the effect of LASC (low serum cultured adipose cell derived stem cells) in animal model of liver injury. The results were as below; (1) In ConA-induced acute liver injury mice, LASC showed significant suppression of serum ALT elevation compared with control mice. (2) Intrahepatic ｍRNA expression of IL-6, IL-10, IFN-γ were downregulated and TGF-βwas upregulated in LASC administrated mice compared with control mice. CD3, CD4, CD8, CD11b and CD11c mRNA expression were also downregulated. (3) In vitro culuture with mouse splenocyte, coculture with LASC downregulate the expression of CD3 in splenocyte, however, expression of NK1.1 and CD19 did not change.
These data suggested that LASC have immunomoduratory effect to supress liver injury in the animal model for acute liver injury, especially through the immunomodulatory effect for T cells.
