MSC immunophenotyping and multilineage differentiation potential.

<p>(A) Analysis of surface antigen marker by flow cytometry for cells obtained from Donor 1. Cells were stained with CD73, CD90 and CD105 antibodies. The IgG isotype was used as control; (B) Ability to differentiate into several lineages: Osteogenic differentiation was indicated by the ALP and Von Kossa staining (upper panel). Adipogenic differentiation (left lower panel) is visually marked by accumulation of neutral lipid vacuoles in culture (Oil Red-O staining). Chondrogenic differentiation (right lower panel) is visually marked by Alcian Blue staining.
