Characterization of ASCs by surface marker phenotype and differentiation potential. ASCs were assessed for the presence of mesenchymal stem cell properties. (a) Immunophenotype assessment of ASCs via flow cytometry analysis of the percentage of positive mesenchymal stem cell markers (CD90, CD44, and CD29) and negative hematopoietic markers (CD45). (b) Osteogenic-differentiated cells were analyzed by Alizarin red staining. (c) Adipogenic-differentiated cells were analyzed by oil red O staining.
