| Outline of Final Research Achievements |
Among potential cell-based therapies, adipose-derived stem cells (ASCs) have thought as a promising source of stem cells for tissue regeneration because it contains approximately 1000-fold more stem cells than the bone marrow.
In the present study, we analyzed the structures and expression of marker genes for multipotency, including Oct3/4, Nanog, and Sox2 of murine-derived ASC macrospheroids by in situ hybridization. The microstructures of the ASC macrospheroids were observed by transmission electron microscopy, and cell proliferation in the spheroids was analyzed by enzyme-linked immunoassay for bromodeoxyuridine as well as the growth and osteogenic potential of these macrospheroids in three-dimensional environment and following induction of calcification by co-culture with monocytes.
These results suggested that ASC macrospheroids presented high capacity for dynamic three-dimensional growth, and it might be promoted its osteogenic potential by monocytes.(Preparing for publication)
