Fig. 2. Monocyte viability in percent of living cells for 2 to 10 days. At each time point, monocytes were stained with trypan blue and cells were revised throughout the cultures in representative preselected micrographic fields at x100 magnification. More than 400 cells per field were counted using a grid ocular. Diamonds, monocytes cultured alone; squares, coculture of monocytes with chondrocytes; n=3.
