| Outline of Final Research Achievements |
We performed the isolation of COL7A1-expressing cells in the peripheral blood mononuclear cells. Culture of the peripheral blood mononuclear cells revealed that proliferation of the fusiform cells attached to the culture dish was observed. RT-PCR using total RNA extracted from the fusiform cells demonstrated that these cells expressed not only moderate COL7A1 expression but also weak CD45 and strong CD105 expressions. Immunofluorescence examinations showed that the fusiform cells were COL7A1+, CD29+, CD45-, CD34-, the same expression pattern as the mesenchymal stem cells. These findings strongly suggest that the mesenchymal stem cells circulate in the peripheral blood, which can be cultured as fusiform cells expressing COL7A1.
