Figure 2

Graph to show numbers of cells captured in 3D gelatin scaffold ('Gelfoam'). It can be seen that cells were detected in the Gelfoam scaffold at days 11 and 20 in all three culture conditions. At day 11 and day 20 there were significantly reduced numbers of chondrocytes in the Gelfoam in the samples cultured in the presence of 100 ng/ml BMP-2 (*). At day 20 there was a significant decrease in cell numbers in all three experimental conditions.
