| Outline of Final Research Achievements |
It is known that the efficiency of mitochondria transfer into cells in primary cultured cells is low efficiency. Therefore, we focusing on TAT peptide known as the cell membrane penetrating peptide, we have constructed a system that can high-efficiently transfer mitochondria into primary cultured cells. We introduced mitochondria using this TAT dextran and showed that the introduction efficiency of mitochondria improves on rat neonatal cardiomyocytes (RNCM), and it reduces the apoptosis induction rate of hydrogen peroxide treated RNCM. In the future, we will evaluate the mitochondrial function using the oxygen consumption rate as an indicator for mitochondrial activity of RNCM introduced mitochondria.
