Witryna24 lip 2015 · The interaction between Hertwig’s epithelial root sheath (HERS) and the adjacent mesenchyme is vitally important in mouse tooth root development. We … WitrynaShh signaling is active in the cervical loop at the bell stage before HERS formation, but is dramatically reduced once the HERS is formed (Nakatomi et al., 2006; Li et al., 2015). The Smad4-mediated Bmp/Tgfβ signaling pathway promotes root formation by regulating Shh signaling in the cervical loop (Li et al., 2015).

The Hertwig epithelial root sheath (HERS) or epithelial root sheath is a proliferation of epithelial cells located at the cervical loop of the enamel organ in a developing tooth. Hertwig epithelial root sheath initiates the formation of dentin in the root of a tooth by causing the differentiation of odontoblasts from the dental papilla. The root sheath eventually disintegrates with the periodontal ligament… WitrynaHertwig's epithelial root sheath (HERS) plays indispensable roles in tooth root development, including controlling the shape and number of roots, dentin formation, and helping generate the cementum.
