Expression of p21^WAF1/CIP1 during mouse odontogenesis

European Journal of Oral Sciences, 1998
p21WAF1/CIP1 is a cyclin‐dependent kinase (Cdk) inhibitor. This protein may function during development as an inducible growth inhibitor that contributes to cell cycle exit and differentiation. The expression pattern of p21 during mouse embryogenesis was correlated with terminal differentiation of multiple cell lineages including skeletal muscles ...

Severe irradiation during odontogenesis

Oral Surgery, Oral Medicine, Oral Pathology, 1963
Abstract Irradiation of susceptible dental structures during their period of development may result in complete anodontia, hypodontia, microdontia, dwarfing of roots, and premature completion of calcification resulting in enamel hypoplasia.

Pathogenesis of primordial odontogenic tumour based on tumourigenesis and odontogenesis.

Oral Diseases, 2018
OBJECTIVE Primordial odontogenic tumour (POT) is a rare benign mixed epithelial and mesenchymal odontogenic tumour. POT is composed of dental papilla-like tissue covered with cuboidal to columnar epithelium that resembles to inner and outer enamel ...

Shear stress facilitates tissue-engineered odontogenesis

Bone, 2006
Numerous studies have demonstrated the effect of shear stress on osteoblasts, but its effect on odontogenic cells has never been reported. In this study, we focused on the effect of shear stress on facilitating tissue-engineered odontogenesis by dissociated single cells.

Case of odontogenesis in an ovarian teratoma

International Journal of Orthodontia and Oral Surgery, 1936
Summary A case of odontogenesis is presented in an ovarian teratoma. The possible etiology of teratoma is briefly discussed. The findings of such tissues which may be related to the teeth are reviewed. A description is given of the pathologic detail pertaining to the odontogenetic tissues.

Albumin Gene Expression During Mouse Odontogenesis

Advances in Dental Research, 1996
Albumin protein is present in developing teeth of several species. Oligomer primers and cRNA probes specific for albumin were designed to perform RT-PCR, and for in situ hybridization, respectively. In situ hybridization failed to reveal albumin expression in any tooth cells, however, albumin PCR products were amplified from tissues adhering to the ...

Aryl sulfatase activity in mouse molar odontogenesis

Acta Histochemica, 1976
Arylsulfatase activity has been studied in the developing molar of the Swiss albino mouse from the lamina stage to the appositional stage. Timed-pregnant Swiss albino mice were utilized in this study. Females were sacrificed by ether anesthesia and fetuses extirpated or newborns anesthetized and decapitated. Frozen sections were fixed and incubated for

The basement membrane of the enamel organ in human odontogenesis

Oral Surgery, Oral Medicine, Oral Pathology, 1984
This study was designed to record findings of a basement membrane in human fetal jaws relative to the oral epithelium, dental lamina, and developing teeth. With the use of Lillie's allochrome stain, this could be followed from the oral epithelium and dental lamina to the tooth jaws.

Contributions of heterospecific tissue recombinations to odontogenesis.

The International journal of developmental biology, 1995
Determining the functions of cell surface and substrate adhesion molecules during heterospecific tissue recombinations constitutes a significant problem in biology. The developing tooth organ provides a fine model to pursue this problem, especially in the context of instructive epithelial-mesenchymal interactions.
