| Outline of Final Research Achievements |
Primary culture of rat cardiomyocytes was conducted, using medium containing one of 5 fatty acids including docosahexaenoic (DHA) and arachidonic (AA) acids. Maximal contractile performance was obtained in cases of 20μM DHA and 50μA AA, with large difference in gene expression. Although combined supplementation of 10μM DHA and 10-20μM AA showed maximal performance of contractility, its level stayed rather close to that obtained in single DHA supplementation.
Primary culture of adult rat adipocytes was superior to that of juvenile one. However, even in the case of DHA supplementation, retaining of adipocytes remained difficult. These results may show effects of fatty acids are dependent on cell species.
