Production of monoclonal antibodies against murine dental papilla
European Journal of Oral Sciences, 1988Abstract – The mesenchymal component of the embryonic tooth, the dental papilla, shows unique cellular behavior. Only the dental papilla cells are capable of differentiating into odontoblasts. The dental papilla also directs the morphogenesis of the tooth.

Cell pellets from dental papillae can reexhibit dental morphogenesis and dentinogenesis
Biochemical and Biophysical Research Communications, 2006We isolated dental papilla mesenchymal cells (DPMCs) from different rat incisor germs at the late bell stage and incubated them as cell pellets in polypropylene tubes. In vitro pellet culture of DPMCs presented several crucial characteristics of odontoblasts, as indicated by accelerated mineralization, positive immunostaining for dentin ...

Expression of intermediate filaments and actins in human dental pulp and embryonic dental papilla
The Anatomical Record, 1992AbstractThe localization of different cytoskeletal proteins (keratin, vimentin, desmin, actin, and α‐smooth muscle actin) was examined by immunohistochemistry in normal human adult dental pulp and compared with dental papilla of tooth germs. Keratin and actin were localized in enamel organ.

AbstractAimTo establish a cell line of immortalized human dental papilla cells (hDPCs).MethodologyPrimary hDPCs were cultured and infected with lentivirus containing the hTERT gene. Integration and transcription of the hTERT gene were verified by PCR. The characteristics of the cells, such as morphology, proliferation and mineralization, were analysed.

Dental Papilla Cells Synthesize But Do Not Deposit Fibronectin in Culture
Journal of Dental Research, 1987The dental papilla cells play a major regulatory role during tooth morphogenesis, and they are the only mesenchymal cells capable of differentiating into odontoblasts secreting dentin. In this paper, we have extended our studies on the behavior of cultured dental papilla cells which have been disaggregated from 17-day mouse embryo teeth.

Mineralized nodule formation by human dental papilla cells in culture
European Journal of Oral Sciences, 1997Human dental papilla cells were enzymatically separated from deciduous tooth germs of an 8‐month‐old embryo legally aborted. the second passage cells were cultured up to 35 days in 3 groups. The β‐gp group was cultured in the Dulbecco MEM containing ascorbic acie and β‐glycerophosphate supplemented with 15% fetal bovine serum.

WNT5A inhibits human dental papilla cell proliferation and migration
Biochemical and Biophysical Research Communications, 2009WNT proteins are a large family of cysteine-rich secreted molecules that are linked to both canonical and non-canonical signal pathways, and have been implicated in oncogenesis and tissue development. Canonical WNT proteins have been proven to play critical roles in tooth development, while little is known about the role of non-canonical WNT proteins ...

An investigation of S-100 protein in embryonic dental papillae of rats
Oral Surgery, Oral Medicine, Oral Pathology, 1984We attempted to identify S-100 protein, a marker of neural crest tissue, within cells of the developing dental papillae of 18-day rat fetuses by means of the immunoperoxidase technique. Although there is experimental evidence that dental papillae are derived from neural crest, no marker protein was identified in this study.

The molecular specificity of the dental papilla of a bell-stage tooth was studied by production of dental-papilla-reactive monoclonal antibodies (Mabs). One of the Mabs, designated 7C5, recognized an epitope present in glycosaminoglycan. Several lines of evidence suggested that the 7C5-epitope consists of chondroitin 6-sulfate.

Abstract First molar tooth germs were dissected from mandibles of mouse embryos 16, 17, 18 and 19 days of gestational age. The tooth rudiments were separated into dental papilla, dental sac and enamel organ after enzymic digestion. These embryonic dental tissues were recombined and grown for 4 weeks in anterior chambers of eyes of homologous adult ...
