FIG. 2.

Adhesion rates among scaffolds. Cells were inoculated onto scaffolds and allowed to adhere for 2 h at 37°C /5% CO₂, after which time the scaffolds were washed twice with PBS and digested with proteinase K. The lysates were stained with picogreen to quantitate DNA. p<0.01 S(P) gel versus allograft; p<0.001 S(P) gel versus all other groups; p<0.001 allograft versus each of the three ceramics; p<0.01 ACS versus Ceramic #3, p<0.001 ACS versus Ceramic #s 1 and 2. Data are representative of three independent experiments.
