Supporting evidence for the role of Msx and Pax gene.

I. Mimura S et al., 2016 [41]	Msx: Association between BMP in neural crest development.
Feng X et al., 2013 [42]	Cell cycle regulation of dental mesenchymal cells. Inhibition of BMP-2 and BMP-4 expression during cap stage.
Lin D et al., 2007 [37]	Expressed in mesenchyme, including the dental papilla; also in inner enamel epithelium.
Tucker et al.,1998 [43]	Emphasis on relation between BMP-4 and Msx-1 in odontogenic mesenchyme.
Thesleff I et al.,1996 [44]	Msx-1 and Msx-2 in the dental mesenchyme induced by BMP.
II. Paixao-Cortes VR et al., 2015 [47]	Pax: Present in embryogenesis as well as in adult organogenesis. Pax-9 important for odontogenesis.
Hlouskova A et al., 2015 [48]	Pax-9 – transcription factor regulates mesenchymal odontogenic molecule expression. Mutation may cause tooth agenesis.
Abu-Hussein M et al., 2015 [49]	Pax-9 mutation may lead to oligodontia or hypodontia
Walton VT et al., 2014 [50]	Examined the co-existence between Msx and Pax gene in tooth agenesis. Assessed the importance of other genes in agenesis.
