Sentences with word «somite»

Working at the Marine Biological Laboratory, Criswell used fluorescent cell tracking to determine that skates form their spines from somites alone.

Preliminary data we have now obtained further indicate that in somite cells, the activation of the NOTCH pathway triggers a «signalling module» that couples the initiation of myogenesis with the epithelial - mesenchymal transition (EMT) that allows them to migrate into the growing muscle.

We have recently shown that in avian embryos, muscle formation is initiated by Delta1 - positive neural crest cells migrating from the dorsal neural tube that, in passing, trigger NOTCH signalling and myogenesis in selected epithelial somite progenitor cells, allowing them to migrate into the nascent muscle to differentiate.

In chick embryos, skeletal muscle formation is initiated by migrating Delta1 - expressing neural crest cells that trigger NOTCH signaling and myogenesis in selected epithelial somite progenitor cells, which rapidly translocate into the nascent muscle to differentiate.

In all land vertebrates (including humans), spines form from only one group of cells called somites.

R. Burgess, P. Cserjesi, K. L. Ligon, E. N. Olson, Paraxis: A basic helix - loop - helix protein expressed in paraxial mesoderm and developing somites.

W. E. Reintsch, A. Habring - Mueller, R. W. Wang, A. Schohl, F. Fagotto, beta - Catenin controls cell sorting at the notochord - somite boundary independently of cadherin - mediated adhesion.

In a study by Junker et al, the authors studied zebrafish embryos at the 15 somites stage by straightening them, then segmenting them into about 100 slices, each roughly 18 µm thick.

Embryonic and adult muscle stem cells: Somites not only supply cells for embryonic muscles, but also contain muscle progenitors.

Ray - finned fishes, however, form their spine from both somites and a separate cell population called chordoblasts.

Since two of the three related groups use only somites in vertebral development, Criswell concluded that the common ancestor for all jawed vertebrates had a backbone derived from somites.

Many animals are built from reiterated parts, such as the segments and appendages of arthropods and the somites and vertebrae of vertebrates.

Interestingly, while not linked to Nanog, the somite segmentation clock gene Hes1 also displays heterogeneous expression that is related to periodic oscillations and differential rates of differentiation [13].
