Abstract/OtherAbstract:
Embryonic epithelium from the mandibular branchial arch organizes the dentition and the deposition of Meckel's cartilage. During 9-11 days of gestation mandibular arch epithelium can induce teeth in nondental ectomesenchyme in both mice and birds. In addition, the deposition of Meckel's cartilage as a rod of cartilage in the middle of the first branchial arch is under the control of the epithelium. The epithelium inhibits chondrogenesis; if it is removed, large amorphous masses of cartilage are found instead of the narrow rod typical of Meckel's cartilage.
