Live-dead assay showing MC3T3-E1 cell line and bovine articular chondrocytes (BCH) at the PS surfaces (e–h) and at the PLLA surfaces (i–p) at day 1 and 7 of culture. Cells were stained with calcein-AM/ethidium homodimer (dead cells stain red and living cells green) and visualized using fluorescence microscopy. A representative picture is shown for each condition. Cell density: 1 × 104 cells/300 μL
