Fig. 7 A new evolutionary scenario of the chordate somite
formation. a In amphioxus, mesoderm/endoderm boundary formation
is organized by Fringe/Delta cassette under Notch signalling. b The
Notch signalling-dependent mechanism of segmental boundary
formation in (a) was co-opted to the future segments in the
anterior PSM of amniotes embryos. The mesoderm is presented
in green. The endoderm is in light blue. The dotted line indicates a
