Figure 1: Expression profile of human adipose derived stem (ADSC). Flow cytomtery analysis revealed ADSC to be positive for CD166, CD90, CD73 and CD44, but negative for hematopoietic surface markers CD34 and CD45 (A). The immunofluorescence staining supported these results (B). The cells were stained with DAPI (blue) to identify the nuclei of the cells and with phalloidin to show the actin filament of the cells (red). The series of the CD proteins were stained in green. The three staining are merged in the last column.
