Witryna3 sty 2024 · Hertwig’s epithelial root sheath (HERS) is important in guiding tooth root formation by differentiating into cementoblasts through epithelial–mesenchymal transition (EMT) and inducing odontoblastic differentiation of dental papilla through epithelial–mesenchymal interaction (EMI) during the tooth root development. Thus, … Witryna17 gru 2008 · Subsequently, root formation proceeded in the culture period. Therefore, disappearance of SR area may be a key event that controls the timing of onset of HERS formation, and Egf may be one of regulatory factors involved in the change from cervical loop epithelium to HERS during root development.
