| Outline of Final Research Achievements |
We performed functional analyses of mixed human cell sheets consisting of human peripheral blood mononuclear cells and human fibroblasts. The amount of vascular endothelial growth factor (VEGF) secreted from mixed human cell sheets was 2-fold higher than that from human fibroblasts. Furthermore, the amount of vascular endothelial growth factor (VEGF) secreted from mixed human cell sheets cultured under hypoxia (2% oxygen) was 2-fold higher than that from mixed human cell sheets cultured under normoxia (20% oxygen). These results revealed that mixture of human peripheral blood mononuclear cells with human fibroblasts and cell culture of mixed human cell sheets under hypoxia lead to enhanced secretion of VEGF.
