Figure 9

Histogram demonstrating expression levels of Sox9 in E11.5 larynx-trachea-lung tissue grown in culture for 48, 72 and 96 hours in juxtaposition to heparin coated glass beads soaked in normal saline or FGF18. Sox9 expression is significantly increased (p<0.05) in the trachea of explants grown in culture with FGF18 only after 96 hours in culture compared to controls. At 48 and 72 hours in culture there is actually a decrease in Sox9 expression in the FGF18 exposed trachea compared to controls. Sox9 expression in E11.5 trachea that is not culture is also included as a control.
