  • Our EmbryoMax Liquid Mouse Embryo Media is produced on a bi-monthly basis. (sigmaaldrich.com)
  • Background: Recent studies have associated the transcription factors, Oct4, Sox2 and Nanog as parts of a self-regulating network which is responsible for maintaining embryonic stem cell properties: self renewal and pluripotency. (lu.se)
  • According to Kime, "perhaps our most important finding was that natural molecules found in the early mouse embryo can reprogram cultured cells to become surprisingly similar in function to early embryos. (sciencedaily.com)
  • The implanted structures often grew and produced many types of cells that resembled those naturally found in early developing embryos. (sciencedaily.com)

  • In addition, the expression of Hat1 is linked to the normal aging process as Hat1 mRNA and protein becomes undetectable in many tissues in old mice. (nih.gov)
  • 4D OCT allowed them to investigate the functional relation between blood flow and heart wall dynamics within different regions of the embryonic heart at a level of detail not currently accessible by other methods. (photonics.com)
  • Histological analyses were performed on the mouse functional genomics platform RIO/Marseille-Nice Genopole with support from the INCA PROCAN program. (plos.org)
  • These services help the scientific community to use the mouse to develop a complete functional annotation of the human genome and thus to better understand human diseases, their physiological and pathological mechanisms. (igbmc.fr)
  • We currently use laboratory mouse to help us understand the biology of heart formation. (stanford.edu)
  • In this fashion, mice or other laboratory animals that exhibit particular traits can be created for specialized studies, or herds of farm animals (such as goats, sheep or cows) can be created that produce pharmaceutically useful proteins in their milk. (who.int)
  • That's why Father Pacholczyk, director of education at the National Catholic Bioethics Center in Philadelphia, said that the efforts to help people understand the immorality of embryo reserch, including human cloning, must focus on humanizing the issue and appreciating our own embryonic origins, not just on the desired results of embryonic or other types of stem-cell research. (archstl.org)
  • A decade later, cloning came to the forefront in Missouri with the narrow passage of Amendment 2, a ballot initiative in 2006 that constitutionally protects embryonic stem-cell research and human cloning. (archstl.org)
  • The Catholic Church has always held that stem-cell research and therapies are morally acceptable, as long as they don't involve the creation and destruction of human embryos. (archstl.org)
  • This approach is extremely valuable because it could bypass the technical and ethical issues of using natural embryos in research and biotechnology. (disabled-world.com)
  • Given that VSELs do not come from the embryo, they could replace embryonic stem cells in research and medicine. (ca.gov)
  • Some prohibit only cloning for reproductive purposes and allow the creation of cloned human embryos for research, whereas others prohibit the creation of cloned embryos for any purpose. (who.int)
  • So far, the expression pattern and the function of EZH2 have been broadly studied in humans [ 11 ] and mice [ 12 , 13 ]. (hindawi.com)
