WitrynaAt this site, Hertwig's epithelial root sheath (HERS), which derives from the coronoapical extension of the inner and outer enamel epithelium (see Chapter 5 ), is believed to send an inductive message, possibly by secreting some enamel proteins or other epithelial product, to the facing ectomesenchymal pulp cells. WitrynaDuring root formation the inner layers of epithelium disappear and only the basal layers are left creating Hertwig's epithelial root sheath (HERS). At this point it is usually referred to as HERS instead of the cervical loop to indicate the structural difference. Cervical loop as epithelial stem cell niche [ edit]
