Hertwig’s Epithelial Root Sheath Fate during Initial Cellular Cementogenesis in Rat Molars
To elucidate the fate of the epithelial root sheath during initial cellular cementogenesis, we examined developing maxillary first molars of rats by immunohistochemistry for keratin, vimentin, and tissue non-specific alkaline phosphatase (TNALP) and by TdT-mediated dUTP nick end labeling (TUNEL). The advancing root end was divided into three sections, which follow three distinct stages of initi...
متن کاملAmeloblastin in Hertwig’s Epithelial Root Sheath Regulates Tooth Root Formation and Development
Tooth root formation begins after the completion of crown morphogenesis. At the end edge of the tooth crown, inner and outer enamel epithelia form Hertwig's epithelial root sheath (HERS). HERS extends along with dental follicular tissue for root formation. Ameloblastin (AMBN) is an enamel matrix protein secreted by ameloblasts and HERS derived cells. A number of enamel proteins are eliminated i...
متن کاملHertwig's epithelial root sheath cells do not transform into cementoblasts in rat molar cementogenesis.
It is generally accepted that cementoblasts originate in the process of differentiation of the mesenchymal cells of the dental follicle. Recently, a different hypothesis for the origin of cementoblasts has been proposed. Hertwig's epithelial root sheath cells undergo the epithelial-mesenchymal transformation to differentiate into cementoblasts. To elucidate whether the epithelial-mesenchymal tr...

15 صفحه اولHertwig’s epithelial root sheath: A panaromic view
The Hertwig’s epithelial root sheath is a transient structure formed in the early period of root formation. It has an important role in regulation and maintenance of the periodontal ligament space, prevention of root resorption and ankylosis, maintenance of periodontal ligament homeostasis, Induction of acellular cementum formation, as a stem cell in periodontal regeneration and also as a stimu...
