EGF and chronic obstructive pulmonary disease: Interestingly the ability of TC ASK 10 to inhibit mitogen-induced ASM cell growth was reduced as we only obtained statistical differences at the highest concentration (1μM) in FBS (Figure 2D) and PDGF (Figure 2E) treated cells while the inhibition in EGF-treated ASM cells was comparable to COPD cells (Figure 2F).
