Dental enamel can be grown using cultured cells

It is a known fact that dental enamel cannot regenerate itself since it is formed from cell layers which are lost by the time the tooth appears and hence the same enamel suffers wear and tear over the remaining human life. University of Tokyo researchers have created a new technique which can culture cells for producing enamels. They demonstrated that epithelial cells which were extracted from growing teeth of a six month old pig continued to grow when they were cultured on special feeder layers of cells. Now since researchers have attained success in the case of dental epithelial cells they could deploy the same technique in the case of dental mesenchymal cells and tooth formation. This technique could also be deployed for replacing damaged enamel and regeneration of the teeth. Via biologynews
