ZPA's role in establishing polarity and further limb development [21] The ZPA first specifies anterior-posterior polarity (and dictates digit identity), and then, by sustaining AER activity, it ensures that … Se mer The limb bud is a structure formed early in vertebrate limb development. As a result of interactions between the ectoderm and underlying mesoderm, formation occurs roughly around the fourth week of development. In Se mer The Hox genes, which define features along the anterior-posterior axis of a developing organism, determine at which points along the axis … Se mer FGF10 can induce limb formation, but T-box proteins, Pitx1, and Hox genes determine identity By mimicking the initial FGF10 secretions of the lateral plate mesoderm cells, limb development can be initiated. Other signaling molecules … Se mer Within the limb bud, expression of specific Hox genes varies as a function of the position along the anterior-posterior axis. The Se mer Associated molecules include: • FGF10 – Initially, Tbx proteins induce secretion of FGF10 by cells in the lateral plate mesoderm. Later, FGF10 expression is restricted to the developing limb mesenchyme, where it is stabilized by WNT8C or Se mer
