Fate of HERS during tooth root development - ScienceDirect

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 … See more Hertwig epithelial root sheath is derived from the inner and outer enamel epithelium of the enamel organ. See more The sheath is also responsible for multiple or accessory roots (medial growth) and lateral or accessory canals in the root (break in epithelium). It is controversial, but HERS may be … See more Hertwig epithelial root sheath was not discovered in any mammalian species. Instead this epithelial structure was discovered by Oskar Hertwig in 1874 in an amphibian (see notes below for further discussion in other animals). See more While in mammals the HERS is rather a transient structure, in amphibians it is more or less a permanent one.
