abstract = {In vertebrates, the three orthogonal body axes,
anteroposterior (AP), dorsoventral (DV) and left-right (LR)
are determined at gastrula and neurula stages by the
Spemann-Mangold organizer and its equivalents. A common
feature of AP and DV axis formation is that an evolutionary
conserved interplay between growth factors (Wnt, BMP) and
their extracellular antagonists (e.g. Dkk1, Chordin) creates
signaling gradients for axial patterning. Recent work showed
that LR patterning in Xenopus follows the same principle,
with R-spondin 2 (Rspo2) as an extracellular FGF antagonist,
which creates a signaling gradient that determines the LR
vector. That a triad of anti-FGF, anti-BMP, and anti-Wnt
governs LR, DV, and AP axis formation reveals a unifying
principle in animal development. We discuss how cross-talk
between these three signals confers integrated AP-DV-LR body
axis patterning underlying developmental robustness, size
scaling, and harmonious regulation. We propose that
Urbilateria featured three orthogonal body axes that were
governed by a Cartesian coordinate system of orthogonal
Wnt/AP, BMP/DV, and FGF/LR signaling gradients.},
