• 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)
  • somatic
  • Embryonic somatic nerve destruction with beta-bungarotoxin. (biomedsearch.com)
  • The effects and time course of a single injection of beta-bungarotoxin into E14 rat embryos were examined with an electron-microscopic study of development of the internal intercostal somatic nerve. (biomedsearch.com)
  • The production of Dolly showed that genes in the nucleus of such a mature differentiated somatic cell are still capable of reverting to an embryonic totipotent state, creating a cell that can then go on to develop into any part of an animal. (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.

  • 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.

  • Overall, the abundance of toxins contained within cigarette smoke that is inhaled by the mother exerts a direct impact by altering the placental and fetal cell proliferation and differentiation. (wikipedia.org)
  • 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)
  • Early
  • CONCLUSIONS: Unless the in utero development of dermatoglyphics in relation to blood pressure is substantially different between singleton and twin pregnancies, there are no useful relationships between dermatoglyphics and hypertension or strong relationships between the presence of certain 'dermatoglyphic markers of impaired fetal development' and blood pressure in subjects who remain normotensive until early in their seventh decade.

  • 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)
  • research
  • Reynolds began teaching in the College of Medicine at the University of Illinois in 1965, where she also conducted research on embryonic and fetal development, child nutrition, and pancreatic disease. (wikipedia.org)
  • Current psychiatric research into the development of the disorder is often based on a neurodevelopmental model (proponents of which see schizophrenia as a syndrome. (wikipedia.org)
  • utero
  • The association of in utero exposure to such carcinogens and the subsequent development of cancer has been reported for all childhood cancers combined and particularly for childhood acute lymphoblastic leukemia, lymphoma, and brain tumors. (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)
  • Terms
  • Tbx2 and Tbx3 are the only T-box transcription factors that act as transcriptional repressors rather than transcriptional activators, and are closely related in terms of development and tumorigenesis. (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)
