(A,C) Quail mandibles harvested at HH24 and cultured for 2 days show robust histological staining throughout Meckel’s cartilage (Alcian Blue). (B,D) Those mandibles treated biochemically with SU5402, which inhibits FGF signaling, lack cartilage matrix staining. (E) Collagen type II protein (Col2) is detected in control mandibles after 2 days of culture. (F) No Col2 protein is observed following treatment with SU5402.
