Limited Adipogenic Differentiation Potential of Human Dental Pulp Stem Cells Compared to Human Bone Marrow Stem Cells.

Bone marrow and teeth contain mesenchymal stem cells (MSCs) that could be used for cell-based regenerative therapies. MSCs from these two tissues represent heterogeneous cell populations with varying degrees of lineage commitment. Although human bone marrow stem cells (hBMSCs) and human dental pulp stem cells (hDPSCs) have been extensively studied, it is not yet fully defined if their adipogenic potential differs.

Organotypic 3D Cellular Models Mimicking the Epithelio-Ectomesenchymal Bilayer During Odontogenesis.

Odontogenesis, the intricate process of tooth development, involves complex interactions between oral ectoderm epithelial cells and ectomesenchymal cells derived from the cephalic neural crest, regulated by major signaling pathways. Dental developmental anomalies provide valuable insights for the clinical diagnosis of rare diseases. More than 30% of patients with rare diseases who undergo molecular analysis suffer from diagnostic errancy.

: Next-generation sequencing sheds light on Witkop's classification.

Amelogenesis imperfecta (AI) is a heterogeneous group of genetic rare diseases disrupting enamel development (Smith et al., Front Physiol, 2017a, 8, 333). The clinical enamel phenotypes can be described as hypoplastic, hypomineralized or hypomature and serve as a basis, together with the mode of inheritance, to Witkop's classification (Witkop, J Oral Pathol, 1988, 17, 547-553).

Implication of Toll/IL-1 receptor domain containing adapters in -induced inflammation.

Periodontitis is induced by periodontal dysbiosis characterized by the predominance of anaerobic species. TLRs constitute the classical pathway for cell activation by infection. Interestingly, the Toll/IL-1 receptor homology domain adapters initiate signaling events, leading to the activation of the expression of the genes involved in the host immune response.
