Histogram demonstrating expression levels of Sox9 in E12.5 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 after 72 hours in culture compared to controls. At 48 and 96 hours in culture there is no significant difference in Sox9 expression in the FGF18 exposed trachea compared to controls. Sox9 expression in E12.5 larynx-trachea that is not culture is also included as a control.
