Expression of intermediate filaments and actins in human dental pulp and embryonic dental papilla

The Anatomical Record, 1992
AbstractThe 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.

Formation of bone-like tissue by dental follicle cells co-cultured with dental papilla cells

Cell and Tissue Research, 2010
During tooth root formation, dental follicle cells (DFCs) differentiate into osteoblasts/cementoblasts when they are in contact with pre-existing dentin. Since some factors of dentin matrix were also produced by dental papilla cells (DPCs) and could induce DFCs differentiation, we hypothesized that DPCs can directly promote DFCs differentiation and ...

Hard tissue-forming potential of stem/progenitor cells in human dental follicle and dental papilla

Archives of Oral Biology, 2010
The existence of stem/progenitor cells in dental tissue has been suggested but their characterization in the human tooth germ remains elusive. The purpose of this study was to investigate these cells in human dental follicles and dental papillae at the crown-forming stage and compare their potential for hard tissue formation.We used dental follicle ...

Immortalization and characterization of human dental papilla cells with odontoblastic differentiation

International Endodontic Journal, 2012
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.

In Vitro Osteogenic Differentiation of Cultured Human Dental Papilla-Derived Cells

Journal of Oral and Maxillofacial Surgery, 2009
This study examined the osteogenic phenotypes and mineralization of cultured human dental papilla-derived cells.Dental papillae were harvested from mandibles during surgical extraction of lower impacted third molars from 3 patients aged 13 to 15 years. The dental papilla-derived cells were introduced into the cell culture.

Dental Papilla Cells Synthesize But Do Not Deposit Fibronectin in Culture

Journal of Dental Research, 1987
The 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.

Hepatocyte Growth Factor Exerts Promoting Functions on Murine Dental Papilla Cells

Journal of Endodontics, 2009
Hepatocyte growth factor (HGF) is a potent mitogenic and angiogenic factor involved in the development of many tissues including the teeth. We previously reported that dental pulp cells express the HGF receptor c-met and that HGF can enhance cell proliferation and differentiation.

Bovine dental papilla‐derived cells immortalized with HPV 18 E6/E7

European Journal of Oral Sciences, 2000
In vitro investigations of cell‐specific metabolism and cell interactions as well as biocompatibility studies are often hampered by the limited lifespan of primary cells originating from target tissues like the oral mucosa, gingiva or pulp. Pulp cells, as do other primary cells, undergo senescence after several passages in vitro.

Profiling the Secretome of Human Stem Cells from Dental Apical Papilla

Stem Cells and Development, 2016
Recent studies have shown that secretion of bioactive factors from mesenchymal stem cells (MSCs) plays a primary role in MSC-mediated therapy; especially for bone marrow-derived MSCs (BMSCs). MSCs from dental apical papilla (SCAPs) are involved in root development and may play a critical role in the formation of dentin and pulp.
