In addition, under conditions of morbidity, the expression of Grp78 was found to be increased in ameloblasts involving ER stress induced by fluoride (Zhang et al., 2016), which causes fluorosis enamel.
These FGFs expressed in mesenchyme are essential for the survival and proliferation of epithelial stem cells in the forming cervical loops; nevertheless, they are not essential for early ameloblast differentiation [79, 80].

EH is caused by a physical disruption in the ameloblasts during the tooth development.
Enamel hypoplasia was defined by a reduced deposition of the enamel matrix by the ameloblasts. This alteration is clinically featured by depressions or grooves on the surface of the tooth.
However, excessive fluoride in drinking water, exceeding a concentration of 0.5-1.5mg/l, can lead to metabolic alteration in ameloblasts; this results in a defective matrix and improper calcification of teeth, known as dental fluorosis [4].
Other studies suggested that the ability of iPS cells to differentiate into ameloblasts and odontogenic mesenchymal cells is promising in tooth bioengineering [9, 12].
The basal cells of the epithelial lining were mainly columnar and similar to ameloblasts and the overlying layers were loosely arranged, resembling the stellate reticulum of the enamel organ.
FAM20C is mainly expressed in osteoblasts, odontoblasts and ameloblasts in skeletal and dental tissues and is a novel FGF23 regulator (95,96).
