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 ...

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.

Dental Apical Papilla as Therapy for Spinal Cord Injury
Journal of Dental Research, 2015Stem cells of the apical papilla (SCAP) represent great promise regarding treatment of neural tissue damage, such as spinal cord injury (SCI). They derive from the neural crest, express numerous neurogenic markers, and mediate neurite outgrowth and axonal targeting.

Hepatocyte growth factor/scatter factor (HGF/SF), a broad-spectrum and multifunctional cytokine, is essential for the development of tissues including tooth. Here it was found that the HGF/SF content of human dental papillae obtained from 8 to 16-year-old individuals decreased significantly with age.

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 ...

Cytoskeleton of the Mesenchymal Cells of the Rat Dental Papilla and Dental Pulp
Connective Tissue Research, 1995This study describes the immunolocalization of actin, cytokeratins and vimentin during differentiation of the dental papilla in the rat. Incisors and first molars were sectioned from mandibles of Wistar rats from embryonic day (E)-14 to (E)-21 and weeks 1, 2, 3, 12 and 104 after birth, fixed in 90% alcohol, decalcified in EDTA, infiltrated with 5 ...

Apical Papilla Regulates Dental Follicle Fate via the OGN-Hh Pathway
Journal of Dental Research, 2022Root apical complex, including Hertwig’s epithelial root sheath, apical papilla, and dental follicle (DF), is the germinal center of root development, wherein the DF constantly develops into periodontal tissue. However, whether DF development is regulated by the adjacent apical papilla remains largely unknown.

Calcification of the dental papilla. A rare finding
British Dental Journal, 1989An interesting case is reported, of calcification of the dental papilla. As yet, little is known about this asymptomatic calcification, which constitutes a rare radiographic finding, deforming the root of a vital tooth, generally a lower premolar or canine.

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.

Dental pulp and apical papilla cells senescence: causes, consequences, and prevention
Biogerontology, 2023Dental pulp under physiological conditions has a defense function, repair capacity, and important mechanisms in pathological processes. In addition, the dental papilla is involved in important defense processes and an essential function in the pulp revascularization process.
