Mouse Bmp4 expression limb and face.
During gastrulation the BMP pathway is antagonised and involved with neural induction. Neural induction signaling through the BMP-regulated Smad1/5 proteins appears to be controlled by fibroblast growth factor (FGF)-regulated Ca2+ entry activating calcineurin (CaN) that in turn dephosphorylates Smad1/5 proteins.

Bmp2, Bmp4 and Bmp7 are co-required in the mouse AER for normal digit patterning but not limb outgrowth
- "Outgrowth and patterning of the vertebrate limb requires a functional apical ectodermal ridge (AER). The AER is a thickening of ectodermal tissue located at the distal end of the limb bud. Loss of this structure, either through genetic or physical manipulations results in truncation of the limb. A number of genes, including Bmps, are expressed in the AER. Previously, it was shown that removal of the BMP receptor Bmpr1a specifically from the AER resulted in complete loss of hindlimbs suggesting that Bmp signaling in the AER is required for limb outgrowth. In this report, we genetically removed the three known AER-expressed Bmp ligands, Bmp2, Bmp4 and Bmp7 from the AER of the limb bud using floxed conditional alleles and the Msx2-cre allele. Surprisingly, only defects in digit patterning and not limb outgrowth were observed. In triple mutants, the anterior and posterior AER was present but loss of the central region of the AER was observed. These data suggest that Bmp ligands expressed in the AER are not required for limb outgrowth but instead play an essential role in maintaining the AER and patterning vertebrate digits."

Regulator of Spatial BMP Activity, Neural Plate Border Formation, and Neural Crest Specification in Vertebrate Embryos
- "Bone morphogenetic protein (BMP) gradients provide positional information to direct cell fate specification, such as patterning of the vertebrate ectoderm into neural, neural crest, and epidermal tissues, with precise borders segregating these domains. However, little is known about how BMP activity is regulated spatially and temporally during vertebrate development to contribute to embryonic patterning, and more specifically to neural crest formation. Through a large-scale in vivo functional screen in Xenopus for neural crest fate, we identified an essential regulator of BMP activity, SNW1. SNW1 is a nuclear protein known to regulate gene expression. Using antisense morpholinos to deplete SNW1 protein in both Xenopus and zebrafish embryos, we demonstrate that dorsally expressed SNW1 is required for neural crest specification, and this is independent of mesoderm formation and gastrulation morphogenetic movements. By exploiting a combination of immunostaining for phosphorylated Smad1 in Xenopus embryos and a BMP-dependent reporter transgenic zebrafish line, we show that SNW1 regulates a specific domain of BMP activity in the dorsal ectoderm at the neural plate border at post-gastrula stages. We use double in situ hybridizations and immunofluorescence to show how this domain of BMP activity is spatially positioned relative to the neural crest domain and that of SNW1 expression. Further in vivo and in vitro assays using cell culture and tissue explants allow us to conclude that SNW1 acts upstream of the BMP receptors. Finally, we show that the requirement of SNW1 for neural crest specification is through its ability to regulate BMP activity, as we demonstrate that targeted overexpression of BMP to the neural plate border is sufficient to restore neural crest formation in Xenopus SNW1 morphants. We conclude that through its ability to regulate a specific domain of BMP activity in the vertebrate embryo, SNW1 is a critical regulator of neural plate border formation and thus neural crest specification."
