Outline of Final Research Achievements

Mesenchymal stem cell is one of the expected cell source for the regenerative medicine. However, the regulatory mechanism and useful markers for the ability is not well characterized. In this project, we explored the regulatory genes that could control cell proliferation and differentiation of human adipose tissue-derived stem cells. In addition to this, we also examined the recently reported cell surface marker, SSEA-3 using skin ulcer model mice. Unfortunately, we had a difficulty to optimize the screening conditions to identify the regulatory genes for cell proliferation and differentiation ability of mesenchymal stem cells. As for the cell surface marker SSEA-3, we have observed that promising therapeutic potential of SSEA-3-positive Muse cells in this mouse model.
