Figure 3. The influence of noggin incubated with OFE on ALP activity of ST2 cells. OFE (40 µg/mL) and noggin (1, 10, 100, or 300 ng/mL) were incubated for 1 hr and then added to the cells. ALP activity was measured 72 hrs later. Data are means ± SE of three culture wells. Significantly different from culture without noggin at *p < 0.05.
