| Outline of Final Research Achievements |
Because amnion lacks in immunogenicity and includes a lot of mesenchymal stem cells, application to regenerative medicine is expected. Based on the study which showed the differentiation from mesenchymal stem cell in the amnion into myocardial cell, we tried to develop the differentiation from amnion to hepatocyte, with putting the amnion in the liver under regeneration stimulus with 70% partial hepatectomy. However, we could not achieve any successful results. Accordingly, we absolutely changed the strategy that we used the amnion as the culture substrate of the hepatocyte, and we found that compared to other culture substrate including ordinary dish or gel, hepatocyte could maintain the function to produce the albumin in amnion. According to these results, amnion might be good culture substrate not only for hepatocyte, but other various cells.
