• neural
  • Even with the recent breakthrough of fetal surgery for myelomeningocele, the emphasis should still be on prevention as the best practice rather than treatment of neural tube defects. (hindawi.com)
  • occurs
  • For example, it has been proven that during exposure nicotine binds to receptors of the fetal cells through which developmentally important signaling occurs in many developing organs and tissues. (wikipedia.org)
  • Cherry angioma may occur through two different mechanisms: angiogenesis (the formation of new blood vessels from pre-existing vessels), and vasculogenesis (the formation of totally new vessels, which usually occurs during embryonic and fetal development). (wikipedia.org)
  • effects
  • Because the binding of these receptors is unanticipated by the regulated activity of the fetal cells it can be inferred that this is a disruption in the cellular process which can lead to detrimental effects such as the deregulation of vital signaling, expression, or repair. (wikipedia.org)
  • cell
  • The study confirms that sensory and motor neurons are much less able to survive axon degeneration on E14 than after the major period of normal cell death (which is nearly over by E18), and that the maintenance and continued development of the perineurium during E14-E16 depends on the presence of peripheral nerve axons.

  • By inhibiting mir-424 in normal endothelial cells they could observe the same increased protein expression of MEK1 and cyclin E1 which, important for the development of senile hemangioma, induced cell proliferation of the endothelial cells. (wikipedia.org)
  • human
  • Layer I, also called the plexiform layer because of the richness in fibers and the paucity of cells, was initially described in the human fetal cerebrum ( Magini, 1888 ). (jneurosci.org)
  • The present study was undertaken to analyze the development and organization of cortical layer I in macaque monkey using [ 3 H]thymidine autoradiography, electron microscopy, immunohistochemistry, and in situ hybridization methods that cannot be used effectively in the postmortem human brain.

  • cells
  • The reprogramming process that cells need to go through during cloning is not perfect and embryos produced by nuclear transfer often show abnormal development. (wikipedia.org)
  • Fetal cells are most sensitive to carcinogens during the early stages of gestation. (wikipedia.org)
  • phenotype
  • Further, the use of these knockout models determined the significance of Tbx2 in the BMP signaling pathway for development of the atrioventricular canal, atrioventricular nodal phenotype, and atrioventricular cushion. (wikipedia.org)
  • early
  • It has been shown that both FBN-1 and FBN-2, along with the other components of elastic fibers, are expressed in the embryonic semilunar valves as early as 4 weeks of gestation. (wikipedia.org)
  • This supports the idea that fibrilin-2 dictates the development of early elastic fibers, while fibrillin-1 provides the structural support of mature elastic fibers. (wikipedia.org)
