  • But we need to proceed carefully, recognizing that we are gaining new powers over human origins even when we do not use human embryos, and recognizing the danger of blurring the line between cellular parts and embryonic wholes. (eppc.org)
  • Multi-cellular organ- pluripotential capacity [ 4 ]. (who.int)
  • Although several techniques for identifying individual exposures have been developed and tested, and although more and more xenobiotics have been recognized to have teratogenic and mutagenic potential, "essentially no specific biomarkers are cur- rently available to indicate that exposure to a given xenobiotic is directly associated with a cellular, subcellular, or phar- macodynamic event" (6). (cdc.gov)
  • Instead of using the word "embryo," for example, early drafts used phrases such as 'child to be' or 'future child. (lifeissues.net)
  • Believing that early human embryos -- indeed even human newborns and young children -- are just "possible people", Hare's edict for sound public policy would be one that "produces that set of people, of all possible sets of people, which will have in sum the best life, i.e., the best possible set of future possible people.

  • A few cases of the importation of Lassa mortality10,11, hence, early identification of infected virus into other parts of the world for example by individuals is important for prompt implementation travellers were documented17-20. (folkhalsomyndigheten.se)
  • These models enable controlled experiments on gene functions that are difficult to conduct with natural embryos. (iasgyan.in)
  • To assess the toxic effects on the whole body of repeated sub-lethal doses of a chemical (i.e. the dosing is intended to show poisoning effects on internal organs, the nervous system etc. up to but not including death). (choosecrueltyfree.org.au)
  • It leaves one breathless to see how far our culture has come to caving in to political correctness -- without the least consideration as to the destructive and lethal consequences not only to these "embryos" but to adult members of our society at large. (lifeissues.net)
  • Similarly, there was interest in using the procedure to produce cloned tissue and organs for possible future transplantation in the nuclear donor and perhaps other tissue- compatible recipients. (who.int)
  • Called a savior sibling, such an embryo deemed free of disease is implanted with the intent to be born to serve as a stem cell or organ donor to the diseased sibling, explained Susan Wolf, JD, McKnight Presidential Professor of law, medicine and public policy at the University of Minnesota in Minneapolis.

  • I will be learning more about the latest developments in areas such as tissue engineering, organ-on-chip technologies, microfluidics and organoids - all areas that are relevant and important to EMBL Barcelona. (embl.org)
  • The Chinese researchers did not plan to produce a baby - they used defective human embryos - but did hope to end up with an embryo with a precisely altered gene in every cell but no other inadvertent DNA damage. (grist.org)
