    ..A key step in the transition from an immature proliferative state to a committed state in eye development is the repression of hth by the BMP-4 homolog Decapentaplegic (Dpp). ..
  8. Barros R, Pereira B, Duluc I, Azevedo M, Mendes N, Camilo V, et al. Key elements of the BMP/SMAD pathway co-localize with CDX2 in intestinal metaplasia and regulate CDX2 expression in human gastric cell lines. J Pathol. 2008;215:411-20 pubmed publisher
    ..In conclusion, we identified for the first time that the BMP pathway is active in intestinal metaplasia and that BMP2 and BMP4 regulate CDX2 expression and promote intestinal differentiation through the canonical signal transducers. ..
