(a) Meniscal cells and chondrocytes exhibited similar immunopositivity for most of the markers investigated at passage 0. A greater percentage of meniscal cells were positive for CD49b, CD49c and CD166 compared with chondrocytes (10 donors); (b) A similar pattern was found for CD49b and CD49c immunopositivity across the cell types at passage 2 (6 donors). Data shown are the means ± the standard deviation.
