| Outline of Final Research Achievements |
This study aimed at the establishment of effective methods to prepare the functional cell aggregates by 1) generating cells (donor cells) that provide appropriate microenvironment for the functional differentiation of stem cells (accepter cells), 2) co-culture with donor and acceptor cells in three dimensional cell aggregates, and 3) effective removal of the donor cells. The processes of step 1 and 2 have been successful, however, the selective elimination of the donor cells (step 3) appeared to be difficult. Thus, an alternative approach was carried out, that is, the preparation of acceptor cells in which genes of proteins from the donor cells responsible for differentiation-induction were expressed under the strict control with tetracycline. By this approach, cell aggregates composed of functional cells, including cardiomyocytes, keratinocytes, chondrocytes and mammary epithelial cells, were prepared.
