Flow cytometry identification of mouse mesenchymal stem cells (MSCs). Cell surface markers of MSCs, including CD44, CD29, CD117, CD31, CD34 and Sca-1, were analysed with flow cytometry. Red lines represent the isotype controls. Cytofluorometric analyses showed the presence of several molecules such as CD44, CD29, CD34 and Sca-1 but not the presence of CD117 or CD31
