Modern birds do not have teeth. Rather, they develop a specialized keratinized structure, called the rhamphotheca, that covers the mandible, maxillae, and premaxillae. Although recombination studies have shown that the avian epidermis can respond to tooth-inductive cues from mouse or lizard oral mesenchyme and participate in tooth formation, attempts to initiate tooth development de novo in birds have failed. Here, we describe the formation of teeth in the talpid2 chicken mutant, including the… Expand
Evolutionary aspects of the development of teeth and baleen in the bowhead whale
TLDR
The development of teeth and baleen in bowhead whale fetuses is investigated using histological and immunohistochemical evidence and it is proposed that the signaling cascade that forms teeth in most mammals has been exapted to be involved in balean plate ontogeny in mysticetes. Expand
Reptilian tooth development
TLDR
The reptile is introduced as an excellent model in which to study the molecular basis for early dental specification and, most importantly, for tooth replacement. Expand
DEVELOPMENTAL BASIS OF TOOTHLESSNESS IN TURTLES: INSIGHT INTO CONVERGENT EVOLUTION OF VERTEBRATE MORPHOLOGY
TLDR
The results demonstrate that the cellular and molecular mechanisms that regulate early‐stage arrest of tooth development are diverse in tetrapod lineages, and odontogenic developmental programs may respond to changes in upstream molecules similarly thereby evolving convergently with feeding morphology. Expand
Loricarioid catfish evolved skin denticles that recapitulate teeth at the structural, developmental, and genetic levels
TLDR
The results indicate that denticles have re-emerged on the trunk of loricarioid catfishes through the ectopic co-option of the oGRN rather than the resurrection of an ancestral trunk-specific denticle genetic pathway. Expand

TLDR
Observations consistent with previous report that odontogenesis is initially directed by species-specific mesenchymal signals interplaying with common epithelial signals. Expand
Developmental genetic mechanisms of evolutionary tooth loss in cypriniform fishes
TLDR
Analysis of orthologous genes in the Japanese medaka and a catfish suggests that expression was lost in cypriniforms, rather than gained in Astyanax, and hypothesize that a loss of Fgf signaling to oral epithelium was associated with cyPRiniform tooth loss. Expand

Studies of the zebrafish (Danio rerio) promise to contribute much to an understanding of the developmental genetic mechanisms underlying diversification of the vertebrate dentition. ToothExpand
A comparative examination of odontogenic gene expression in both toothed and toothless amniotes.
TLDR
It is demonstrated that Bmp4, Msx1, and Msx2 expression is limited proximally in the red-eared slider turtle (Trachemys scripta) mandible at stages equivalent to those at which odontogenesis is initiated in mice, a similar finding to previously reported results in chicks. Expand
Chemical manipulation of dental patterning in Malawi cichlids
TLDR
Through in situ hybridization, the teratogens cyclopamine and SU5402 are used to reduce the function of Shh and Fgf protein, respectively with a time and dose dependence to characterized basic patterns of odontogenesis in cichlids that are conserved throughout vertebrates. Expand
The Evolutionary Developmental Control of the Avian Feeding Apparatus
Recent discoveries of exquisitely preserved nonavialan and avialan theropod dinosaurs have not only prompted studies of theropod tooth morphologies, but have also provided information about theExpand

TLDR
Results show that, although latent, the early signaling pathways involved in odontogenesis remain inducible in Aves and suggest that loss of odontogenic Bmp4 expression may be responsible for the early arrest of tooth development in living birds. Expand

TLDR
The first data on operational genes in tooth development is provided to show that the same signalling genes choreograph this evolutionary stable event in fishes since the osteichthyan divergence 420 Myr ago, with the identical spatial–temporal expression as in mammals. Expand
Mouse Otlx2/RIEG expression in the odontogenic epithelium precedes tooth initiation and requires mesenchyme-derived signals for its maintenance.
TLDR
The mouse Otlx2 gene is a new member of the paired-like family of homeobox genes whose human homologue, RIEG, is involved in Rieger syndrome, an autosomal-dominant disorder, and its expression patterns suggest that both genes participate in the reciprocal tissue interactions which are a hallmark of odontogenesis.

Memoirs: The Developmental Mechanics and Potencies of the Undifferentiated Mesenchyme of the Mandible
TLDR
It was demonstrated experimentally that elongation of the mandibular arch to form the jaw is mainly due to apical growth caused by proliferation from the paired chondrogenic centres, and that the cells of the osteogenic proliferation centre in the 4-day mandible are already determined to form bone. Expand
Sonic hedgehog regulates growth and morphogenesis of the tooth.
TLDR
The role of Shh is addressed in the developing tooth in mouse by using a conditional allele to remove Shh activity shortly after ingrowth of the dental epithelium and demonstrating that Shh regulates growth and determines the shape of the tooth. Expand

TLDR
Embryonic epithelium from the mandibular branchial arch organizes the dentition and the deposition of Meckel's cartilage during 9-11 days of gestation, which can induce teeth in nondental ectomesenchyme in both mice and birds. Expand
Shh-Bmp2 signaling module and the evolutionary origin and diversification of feathers.
TLDR
It is concluded that Shh and Bmp signaling is necessary for the formation of barb ridges in feathers and that Sho-Bmp2 signaling constitutes a functionally conserved developmental signaling module in archosaur epidermal appendage development. Expand
Development of teeth in chick embryos after mouse neural crest transplantations
TLDR
Evidence of tooth formation is obtained showing that avian oral epithelium is able to induce a nonavian developmental program in mouse neural crest-derived mesenchymal cells. Expand
A zone of frontonasal ectoderm regulates patterning and growth in the face
TLDR
A molecular boundary in the frontonasal process ectoderm was identified, defined by the juxtaposed domains of Fibroblast growth factor 8 and Sonic hedgehog, which presaged the initial site of frontonal process outgrowth and later demarcated the dorsoventral axis of the upper beak. Expand
Wnt/Shh interactions regulate ectodermal boundary formation during mammalian tooth development.
TLDR
It is suggested that Wnt-7b acts to repress Shh expression in oral ectoderm, thus maintaining the boundaries between oral and dental ectodermal cells. Expand
