Title
(EN) MUCOSAL EPITHELIAL CELL SHEET AND METHOD FOR PRODUCING THE SAME
(FR) PLAQUE DE CELLULES EPITHELIALES DE MUQUEUSE ET SON PROCEDE DE PRODUCTION
Abstract
(EN) A mucosal epithelial cell sheet consisting of a plural number of layers of oral inner marginal mucosal epithelial cells which adhere to teeth continuously to oral mucosal epithelial cells so as to form a part of the gingival trough. Because of having a potent ability to divide and a low antigenicity, these oral inner marginal mucosal epithelial cells can be prepared within a short time and take over a long period of time.
(FR) L'invention porte sur une plaque de cellules épithéliales des muqueuses constituée d'une pluralité de couches de cellules épithéliales marginales, internes, de la muqueuse buccale, qui adhèrent aux dents en continu de manière à former une partie de la cavité gingivale. Du fait de leur puissante aptitude à se diviser et de leur faible antigénicité, ces cellules peuvent être préparées sur une courte durée et recueillies sur une longue durée.
