The miR-183 family consists of 3 related microRNAs (miR-183, miR-96, miR-182) that are required to complete maturation of primary sensory cells in the mammalian inner ear. Because the level of these microRNAs is not uniform across hair cell subtypes in the murine cochlea, the question arises as to whether hair cell phenotypes are influenced by microRNA expression levels. To address this, we use...

Some clinical case reports have shown that immature permanent teeth with periradicular periodontitis or abscess can undergo apexogenesis after conservative endodontic treatment. A call for a paradigm shift and new protocol for the clinical management of these cases has been brought to attention. Concomitantly, a new population of mesenchymal stem cells residing in the apical papilla of permanen...

Purpose: To investigate the use of tricalcium silicate cement Biodentine as an alternative to MTA in regenerative endodontic procedures by assessing morphology and adhesion stem cells from apical papilla direct contact with these materials Materials/Methods: Glass ionomer cement, disks identical size were created. Stem incubated on disks, their assessed a scanning electron microscope. Results: ...

The Wnt/β-catenin signaling pathway is the main target of tooth regeneration regulation. Treatment cells with AZD2858 stimulates pathway, yet function this in remains unclear. Here, we found that promotes accumulation β-catenin nuclei stem from apical papilla (SCAPs) and enhances cell proliferation. Single-cell sequencing was performed on SCAPs treated AZD2858. Eight clusters were identified, n...

Coordination between the Hertwig’s epithelial root sheath (HERS) and apical papilla (AP) is crucial for proper tooth root development. The hedgehog (Hh) signaling pathway and Nfic are both involved in tooth root development; however, their relationship has yet to be elucidated. Here, we establish a timecourse of mouse molar root development by histological staining of sections, and we demonstra...

It has been reported that a subset of type III taste cells express glutamate decarboxylase (GAD)67, which is a molecule that synthesizes gamma-aminobutyric acid (GABA), and that Mash1 could be a potential regulator of the development of GABAnergic neurons via Dlx transcription factors in the central nervous system. In this study, we investigated the expression of GAD67 and Dlx in the embryonic ...
