| Outline of Final Research Achievements |
In acute liver failure, liver regeneration is essential to be cured, however, there are no effective drugs to use for the intervention to the liver regeneration in clinical practice.
We investigated the culture medium of stem cells derived from human exfoliated dedicious teeth (SHED-CM) in animal model of acute liver failure, and showed higher efficacy compared with other stem cells. And as the abundant humoral factors in SHED-CM, we found MCP-1, which is well-known chemoattractant of monocytes-macrophages, and secreted domain of Siglec-9, which is the key factors for transition of pro- to antiinflammatory phase of macrophages, and we also found high efficacy of these two factors for improving survival of animals, supression of the inflammation, and promotion of the hepatocyte regeneration.
These two factors might become hopeful tools for the newly developement of the drugs for acute liver failure.
