How are cells instructed to form somite boundaries by the zebrafish segmentation clock?
In vertebrate embryos, the elongating body axis is patterned via the sequential and rhyth-mic production of segments from a posterior unsegmented tissue called the presomitic mesoderm (PSM). This process is controlled by a population of cellular oscillator ...
EPFL2023Hunting for the wavefront: investigation of somite boundary positioning in zebrafish
Somitogenesis is the rhythmic and sequential formation of somites, which are tissue blocks that give rise to segmented adult body structures including the vertebrae and associated muscle. Somite formation is controlled by the segmentation clock, a populati ...
EPFL2022Preparation of Single-Somite Explants from Zebrafish Embryos
Andrew Charles Oates, Sundar Ram Naganathan
The body axis of vertebrate embryos is periodically subdivided into 3D multicellular units called somites. While genetic oscillations and molecular prepatterns determine the initial length-scale of somites, mechanical processes have been implicated in sett ...
JOURNAL OF VISUALIZED EXPERIMENTS2022Reaction wavefront theory of notochord segment patterning
The vertebrate axis is segmented into repetitive structures, the vertebrae. In fish, these segmented structures are thought to form from the paraxial mesoderm and the adjacent notochord. Recent work revealed an autonomous patterning mechanism in the zebraf ...
