| Research Abstract |
In this study, we examined the role of Rho signaling in ameloblasts differentiation and stem cell maintenance. The experiments using mice with epithelial specific expression of RhoA dominant negative demonstrated that Rho signaling regulated cytoskeletal dynamics and cell adhesion during ameloblasts differentiation. Semaphorin 4D-PlexinB1-LARG signal cascade controlled Rho A activity. Further, since RhoA activity regulated the expression of slug, the transcription factor that controlled epithelial-mesenchymal transition (EMT), it was suggested that EMT regulated ameloblasts differentiation and stem cell maintenance via Rho signaling.
