  • We have analyzed the developmental relationship between two mesodermal tissues in the Drosophila embryo, the gonadal mesoderm and the fat body. (biologists.org)
  • All these properties indicate synchrony and symmetry of formation of the presomitic mesoderm on both sides of the embryo leading to formation of a static embryonic structure with few cell movements. (biologists.org)
  • Furthermore
  • Furthermore, we present evidence from genetic analysis suggesting that, before stage 10 of embryogenesis, gonadal mesoderm and the fat body have not yet been specified as different cell types, but exist as a common pool of precursor cells requiring the functions of the tin, zfh-1 and cli genes for their development.

  • cell
  • Therefore, it appears that mediolateral regionalisation of myotomal precursor cells is a property established before bilateralisation of the presomitic mesoderm and that coherent clonal growth accompanies cell dispersion along both the mediolateral and anteroposterior axes. (biologists.org)
  • cells
  • These findings in the mouse correlate well with what is known in the chick, suggesting conservation of the mode of production and distribution of the cells of the presomitic mesoderm. (biologists.org)
  • These complex molecular processes require precise production and organisation of cells in the presomitic mesoderm. (biologists.org)
  • They indicate a rostrocaudal organisation of the primitive streak, such that the most rostral levels contribute cells in the most medial region of the ingressed mesoderm and suggest some kind of organisation in the node. (biologists.org)
  • The researchers report that ceh-51 is expressed in mesoderm cells and is a direct target of TBX-35. (biologists.org)
