| Outline of Final Research Achievements |
We successfully established the newly culture method for mesenchymal stem cells (MSCs) to keep their stem-ness under shaking condition. MSCs are getting spheroids with shaking culture method. MSC spheroids can supply undifferentiated MSCs for a long period. This technology is patent pending.
Moreover, We try to generate bone tissues with MSC spheroids to apply jaw bone regeneration. From our results, MSC spheroid can re-attach on a culture dish. Then, migrated cells from MSC spheroids are positive for alkaline phosphatase (ALP) after osteogenic induction. However, there are few positive cells in spheroids itself after ALP staining. It suggested that MSC spheroid kept their stem-ness robustly.
From these findings, we are trying to establish the newly osteogenic induction method using MSC spheroids.
