RNA-sequence reads of embryonic tooth germs from the domestic cat, Felis catus
In this study we investigated the genetic differences between three distinct types of teeth (incisor, canine, and premolar) during embryonic development in the domestic cat, Felis catus. Incisor, canine, and premolar teeth differ in the shape and size of the tooth crown in domestic cats and in many other mammals, including humans. Tooth development has been well-studied in laboratory mice, however, mice lack canines and premolars, therefore relatively little is known about the development of different tooth types within the embryo. To address this, we performed RNA-sequencing of dental tissues from deciduous incisor, canine, and premolar teeth to identify genetic differences between each of these tooth types during embryonic development.
