Cell Dev.

The fate and regenerative potential of stem cells are dependent, to a great extent, on their microenvironment, which is composed of various tissue components, cell populations, and soluble factors. N-cadherin-mediated cell\u2013cell interaction has been implicated as an important factor in controlling the cell-fate commitment of mesenchymal stem cells. In this study, the effect of N-cadherin on odontogenic differentiation of DPSCs and the potential underlying mechanisms, both <jats:italic>in vitro<\/jats:italic> and <jats:italic>in vivo<\/jats:italic>, was investigated using a cell culture model and a subcutaneous transplantation mouse model. It was found that the expression of N-cadherin was reversely related to the expression of odontogenic markers (dentin sialophosphoprotein, DSPP, and runt-related transcription factor 2, Runx2) during the differentiation process of DPSCs. Specific shRNA-mediated knockdown of N-cadherin expression in DPSCs significantly increased the expression of DSPP and Runx2, alkaline phosphatase (ALP) activity, and the formation of mineralized nodules. Notably, N-cadherin silencing promoted nucleus translocation and accumulation of \u03b2-catenin. Inhibition of \u03b2-catenin by a specific inhibitor XAV939, reversed the facilitating effects of N-cadherin downregulation on odontogenic differentiation of DPSCs. In addition, knockdown of N-cadherin promoted the formation of odontoblast-like cells and collagenous matrix in \u03b2-tricalcium phosphate\/DPSCs composites transplanted into mice. In conclusion, N-cadherin acted as a negative regulator via regulating \u03b2-catenin activity during odontogenic differentiation of DPSCs. These data may help to guide DPSC behavior by tuning the N-cadherin-mediated cell\u2013cell interactions, with implications for pulp regeneration.<\/jats:p>","DOI":"10.3389\/fcell.2021.661116","type":"journal-article","created":{"date-parts":[[2021,3,30]],"date-time":"2021-03-30T05:31:42Z","timestamp":1617082302000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["N-Cadherin Regulates the Odontogenic Differentiation of Dental Pulp Stem Cells via \u03b2-Catenin Activity"],"prefix":"10.3389","volume":"9","author":[{"given":"Zilong","family":"Deng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenjuan","family":"Yan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingzhu","family":"Dai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ming","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qian","family":"Qu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Buling","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wanghong","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2021,3,30]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"270","DOI":"10.1016\/j.scr.2015.02.002","article-title":"CDH2 and CDH11 act as regulators of stem cell fate decisions.","volume":"14","author":"Alimperti","year":"2015","journal-title":"Stem Cell Res."},{"key":"B2","doi-asserted-by":"publisher","first-page":"1544","DOI":"10.1177\/0022034515601658","article-title":"Pulp-dentin regeneration: current state and future prospects.","volume":"94","author":"Cao","year":"2015","journal-title":"J.
