Fig 2. Immunofluorescence analysis of fibroblast-specific protein 1 (FSP1) and the mesenchymal stem marker CD90.

Fig 2

Human normal prostate fibroblast (NPF) and carcinoma associated fibroblast (CAF) were isolated, double-labeled with antibodies against FSP1 and CD90 and visualized using fluorochrome-conjugated (FITC or TRITC) secondary antibodies. NPF show homogeneous expression of FSP1 and low expression of CD90. However CAF presented not only a heterogeneous expression of FSP1 and CD90 but also high intensity pattern of expression for CD90 positive cells.
