Restriction of sonic hedgehog signalling during early tooth development.
The signalling peptide encoded by the sonic hedgehog gene is restricted to localised thickenings of oral epithelium, which mark the first morphological evidence of tooth development, and is known to play a crucial role during the initiation of odontogenesis. We show that at these stages in the murine mandibular arch in the absence of epithelium, the Shh targets Ptc1 and Gli1 are upregulated in ...
متن کاملMolecular genetics of tooth development.
Organogenesis depends upon a well-ordered series of inductive events involving coordination of molecular pathways that regulate the generation and patterning of specific cell types. Key questions in organogenesis involve the identification of the molecular mechanisms by which proteins interact to organize distinct pattern formation and cell fate determination. Tooth development is an excellent ...
متن کاملRadiographic Evaluation of Dental Development in Patients With Tooth Agenesis
Introduction: Hypodontia is one of the most common developmental anomalies. This study aimed to evaluate the variations of radiographic dental development in a group of Iranian children with dental agenesis. Materials and Methods: This study evaluated 1230 Orthopantomographs (OPGs) for agenesis of permanent teeth obtained from the patients aged between 8 and 18 years. Then the difference betwe...
متن کاملGene Expression Profile Analysis during Mouse Tooth Development
Introduction: Complex molecular pathways involve in development of different tissues such as teeth. Differential gene expression patterns during teeth development generates different tooth types. Teeth development results from interactions between oral epithelium and underlying ectomesenchyme cells with neural crest origin. Teeth development are regulated by different signaling networks. In thi...
متن کاملPostnatal tooth development in cattle.
INTEREST in the teeth of cattle dates from the latter half of the nineteenth century when disputes as to the age of veal carcasses were settled by the state of eruption and amount of wear of the incisor teeth. Recently, additional attention has been drawn to the teeth of cattle by the recognition of the role played by fluorides in the mottling of the teeth. Many studies have been done to classi...
