The isolated cells fulfilled the criteria of MSC stated by ISCT. (a) The shape of cells isolated from the degenerated IVDs. (b) The MSC-associated surface markers (CD34, CD14, CD19, HLA-DR, CD73, CD90, and CD105) were analyzed by flow cytometry. (c) The induction of osteogenic, chondrogenic, and adipogenic differentiation of the isolated cells.
