Figure 1From: Functional investigations on human mesenchymal stem cells exposed to magnetic fields and labeled with clinically approved iron nanoparticlesCharacterization of human MSCs. Specific staining for adipogenesis (lipid vacuoles are stained in red), osteogenesis (alkaline phosphatase is stained in pink-violet) and chondrogenesis (mucopolysaccharides are stained blue-bluish green). Scale bar indicate 50 μm (A). FACS analyses of human MSCs: The MSCs are positive for CD29, CD44, CD59, CD71, CD73, CD90, CD105, CD106, CD146, CD166, CD271, and HLA class I and negative for CD14, CD34, CD45, and HLA class II. Black graph: specific antibody, white graph: isotype control (B).Back to article page
