Nettet14. mar. 2014 · However, at stage 15 to 16, as mesenchyme is being generated, proliferation is uniform throughout the lateral plate mesoderm, including both the trunk and limb-forming fields . Together with the lineage analysis, these observations strongly suggest that the limb bud initiates earlier than stage 17 to 18, through EMT and … Nettet4. apr. 2011 · Therefore, in the limb mesenchyme, Msx genes cannot be considered exclusively as downstream effectors in the BMP signaling pathway. The possible control of Bmp genes by Msx activity in the limb is less documented.

Moreover, we present evidence that, in the limb bud mesenchyme, SF/HGF increases the motility of myogenic precursor cells and has a role in …
