| Outline of Final Research Achievements |
Autologous transplantation of myoblast sheet has attracted attention as a new technique for curing myocardial infarction. Myoblast sheet has the ability to secret cytokines which improve heart function via the facilitation of angiogenesis on affected part. To understand in vivo phenomena and evaluate curative effect after transplantation such as cytokine secretion from transplant and its angiogenesis capability, a multi-layered cell sheet of human skeletal muscle myoblasts (HSMMs) was constructed by originally equipped gelatin stamp system. In the HSMM sheet, active cellular migration occurred in the horizontal and vertical directions anywhere, revealing the sheet fluidity. Dynamic behavior including collective migration and spatial habitation of heterogeneous cells, such as human skeletal muscle fibroblasts (HSMFs) and human umbilical vein endothelial cells (HUVECs), in the fluidic scaffold was clarified.
