    J Jernvall
    Developmental Biology Program, Institute of Biotechnology, Viikki Biocenter, P O Box 56, 00014, University of Helsinki, Helsinki, Finland
    Mech Dev 92:19-29. 2000
    ..Spatiotemporal induction of the secondary enamel knots determines the cusp patterns of individual teeth and is likely to involve repeated activation and inhibition of signaling as suggested for patterning of other epithelial organs...
  2. ncbi The life history of an embryonic signaling center: BMP-4 induces p21 and is associated with apoptosis in the mouse tooth enamel knot
    J Jernvall
    Institute of Biotechnology, University of Helsinki, Finland
    Development 125:161-9. 1998
    ..These results show that the life history of the enamel knot is intimately linked to the initiation of tooth shape development and support the role of the enamel knot as an embryonic signaling center...
  3. ncbi Gene expression patterns associated with suppression of odontogenesis in mouse and vole diastema regions
    S V Keränen
    Developmental Biology Program, Institute of Biotechnology, Biocenter 1, University of Helsinki, P O Box 56, Helsinki, FIN 00014, Finland
    Dev Genes Evol 209:495-506. 1999
    ..However, based on earlier tissue recombination experiments it is conceivable that the developmental arrest is determined by the early oral epithelium...
  4. ncbi Cusp patterning defect in Tabby mouse teeth and its partial rescue by FGF
    J Pispa
    Institute of Biotechnology, Viikki Biocenter, University of Helsinki, Finland
    Dev Biol 216:521-34. 1999
    ..Instead FGF-10 partially restored morphogenesis and stimulated the development of additional tooth cusps in cultured Tabby molars...
  5. ncbi Enamel knots as signaling centers linking tooth morphogenesis and odontoblast differentiation
    I Thesleff
    Developmental Biology Program, Institute of Biotechnology, Vlikki Biocenter, 00014 University of Helsinki, Finland
    Adv Dent Res 15:14-8. 2001
    ..We suggest that the enamel knots are central regulators of tooth development, since they link cell differentiation to morphogenesis...

    A Vaahtokari
    Institute of Dentistry, University of Helsinki, Finland
    Mech Dev 54:39-43. 1996
    ..We suggest that the enamel knot acts as a signaling or organizing center, which provides positional information for tooth morphogenesis and regulates the growth of tooth cusps...
  9. ncbi Evidence for the role of the enamel knot as a control center in mammalian tooth cusp formation: non-dividing cells express growth stimulating Fgf-4 gene
    J Jernvall
    Department of Pedodontics and Orthodontics, University of Helsinki, Finland
    Int J Dev Biol 38:463-9. 1994
    ..Based on these results, we suggest that the enamel knot may control tooth morphogenesis by concurrently stimulating cusp growth (via FGF-4 synthesis) and by directing folding of cusp slopes (by not proliferating itself)...
  10. ncbi Linking development with generation of novelty in mammalian teeth
    J Jernvall
    Institute of Biotechnology, Viikki Biocenter, P O Box 56, FIN 00014, University of Helsinki, Helsinki, Finland
    Proc Natl Acad Sci U S A 97:2641-5. 2000
    ..In phylogenetic studies, small cusps may be unreliable as phylogenetic signals. Population level variation can be a powerful tool in testing and generating hypotheses in developmental evolution studies...
