Paraxis is required for somite morphogenesis and differentiation in Xenopus laevis
(Wiley-liss, Div John Wiley & Sons Inc, 2015-08)
Background: In most vertebrates, the segmentation of the paraxial mesoderm involves the formation of metameric unitscalled somites through a mesenchymal-epithelial transition. However, this process is different in Xenopus ...
Dynamic somite cell rearrangements lead to distinct waves of myotome growth
(Company of Biologists, 2007-04)
The myogenic precursors responsible for muscle growth in amniotes develop from thedermomyotome, an epithelium at the external surface of the somite. In teleosts, themyogenic precursors responsible for growth have not been ...
Morphogens during embryonic development of vertebrates Morfógenos durante el desarrollo embrionario de vertebrados
(Universidad de la Frontera, 2014)
During embryonic development, cells in many tissues differ according to the positional information that is set by the concentration of morphogen gradients. These are signaling molecules that are secreted in a restricted ...
Análise da função biológica da molécula orientadora por repulsão a1 (RGMA1) durante o estabelecimento de precursores musculares em somitos de embriões de galinha in vitro

The Repulsive Guidance Molecule a (RGMa) is a protein originaly described playing
role as a repulsive cue during axonogenesis, via the Neogenin and/or as co-receptors of
the BMP signaling pathways. RGMa expression pattern ...

Síndrome de Klippel Feil: A Propósito de Un Caso
(2021-07-12)
The Klippel-Feil Syndrome (KFS) was first described by Maurice Klippel and Andre Feil in 1912, in a 46-year-old tailor who was admitted for “lung congestion and urinary alterations”. This pathology is characterized for a ...
