• Dorsal
  • Dorsal/ventral patterning of the sea urchin embryo depends upon the establishment of a Nodal-expressing ventral organizer. (nih.gov)
  • It contains the dorsal aorta, genital ridges and mesonephros and lies between the notochord and the somatic mesoderm, extending from the umbilicus to the anterior limb bud of the embryo. (wikipedia.org)
  • development
  • Data are shown as normalized ΔCt (ΔΔCt, left ordinate), and as the corresponding fold difference in transcript abundance (right ordinate), with respect to control unperturbed embryos at the same stages of development. (nih.gov)
  • To investigate whether histone acetylation is involved in the activation of hbox12 gene expression during sea urchin development, Paracentrotus lividus embryos were cultured in the presence of the HDAC inhibitors TSA or valproic acid (VPA). (nih.gov)
  • This paper details the advantages of using C. elegans to investigate features of the nucleolus during the organism's development by following dynamic changes in fibrillarin (FIB-1) in the cells of early embryos and aged worms. (nih.gov)
  • In the course of the development of the embryo, the incus and malleus arise from the same first pharyngeal arch as the mandible and maxilla, and are served by mandibular and maxillary division of the trigeminal nerve. (wikipedia.org)
  • The early embryo requires critical development in the Fallopian tube. (wikipedia.org)
  • early
  • A) P. lividus embryos cultured in the absence or in the presence of either TSA or VPA at the indicated dosages, and observed at the early blastula stage. (nih.gov)
  • B) Northern blot analysis of total RNA isolated from embryos at the early blastula stage treated or not treated with TSA or VPA, and probed with an antisense 32P labelled RNA against the hbox12 transcript. (nih.gov)
  • D) Spatial distribution of the hbox12 transcripts in control and TSA-treated embryos at the early blastula stage, revealed by chromogenic WMISH. (nih.gov)
  • brain
  • At least two other more polar (presumably richer in sialic acid) bands are often visible under XI, both in embryos and in brain and spinal cord tissues of adult Xenopus. (biomedsearch.com)
  • cell
  • This study demonstrates that heterogeneity in surface tension results in significant deviations of cell behavior compared to simple soap bubble models, and thus must be taken into consideration in understanding cell shape within embryos. (biomedsearch.com)
  • The cell-cell contact surfaces in developing embryos are often curved like arcs. (biomedsearch.com)
  • Those of the two-cell stage embryos of C. elegans exhibit this pattern. (biomedsearch.com)
  • Multi-position photoactivation and multi-time acquisition for large-scale cell tracing in avian embryos. (biomedsearch.com)
  • A typical approach consists of fluorescently marking small numbers of cells within a large number of embryos, followed by comprehensive three-dimensional static or time-lapse imaging to map cell positions. (biomedsearch.com)
  • At these dosages, that are commensurate with effective doses determined in studies in mammalian systems [39, the rate of cell division was not altered, and embryos cleaved synchronously with respect to untreated controls (Fig 1A). (nih.gov)
  • The effectiveness of the antioxidants to protect the embryos from ethanol-induced cell death was also evaluated. (zfin.org)
  • Furthermore, isolated organ cultures of the AGM from mice embryos can autonomously initiate hematopoietic stem cell activity, without influence from the yolk sac or liver. (wikipedia.org)
  • shape
  • We are also interested in morphogenesis that provides shape to the developing embryo. (yale.edu)
  • cells
  • SOX1 expression is restricted to neuroectoderm by proliferating progenitor cells in the tetrapod embryo. (wikipedia.org)
  • determine
  • To determine if oxidative stress underlies cardiovascular dysfunction, embryos were co-exposed to ethanol and several antioxidants. (zfin.org)
  • gray
  • The term "tectal plate" (or "quadrigeminal plate") is used to describe the junction of the gray and white matter in the embryo. (wikipedia.org)
