- Phenotypic characterization of HDPF by Fibroblast Surface Protein (FSP) staining. HDPF from 4 different patients (A, B, C and D) were plated (104 cells/well) and showed positive staining for FSP-1 protein (green). Cell nuclei were stained with DAPI- blue (4′,6- diamidino-2-phenylindole dihydrochloride). E – negative control. Images captured by a confocal microscope (TCS model, SPE, Leica®, Mannheim, Germany). Scale bars - 20 μm
