  • Each of those two cells is able to divide indefinitely, "so from a small vial of those cells we could grow up as many cells as we would ever want," Lanza says. (usf.edu)
  • Hair growth in adults occurs naturally in a process known as hair neogenesis â€" where cells called dermal papilla cells that span the top two layers of skin coax surrounding cells to form hair follicles. (baldingblog.com)
  • For the first time, new human hairs have been coaxed into growing from specialised skin cells that can be multiplied in number to potentially create a full head of hair. (baldingblog.com)
  • General Assembly the adoption of a declaration on human cloning by which Member States were called upon to prohibit all forms of human cloning inasmuch as they are incompatible with human dignity and the protection of human life. (who.int)
  • A cloned embryo-like a natural embryo-is an individual organism, a member of its (in this case, human) species. (nationalrighttolifenews.org)
  • Most natural cloning occurs in those species that produce their descendants asexually, that is, without combining the male and female genetic material. (who.int)
  • The process has been difficult to do with human cells. (usf.edu)
  • They repeated the process - this time starting with the genetic material extracted from the skin cells of a much older man. (usf.edu)
  • What we show for the first time is that you can actually take skin cells, from a middle-aged 35-year-old male, but also from an elderly, 75-year-old male" and use the DNA from those cells in this cloning process, Lanza says. (usf.edu)
  • In particular, the efficiency of the process will have to be improved before the technique could be applied in the clinic using human cells. (nih.gov)
  • After that, the question becomes not whether to clone, but what to do with the embryo that was created through the cloning process. (nationalrighttolifenews.org)
  • The predominant bioethical concern arising from this technology is that the blastocyt-stage embryo must be destroyed in the process of isolating and separating the embryonic stem cells from the inner mass region of the pre-embryo. (jcpa.org)
  • A Japanese team at Kyoto University has discovered how to reprogram skin cells so that they "dedifferentiate" into the equivalent of an embryonic stem cell. (blogspot.com)
  • It could be the Holy Grail of stem cell science: a technique that is both feasible and unambiguously ethical. (blogspot.com)
  • Cloning technology, however, is perceived as having the potential for reproductive cloning, which raises serious ethical and moral concerns. (who.int)
  • These stem cells are encouraged to become the type of cells needed (say, insulin cells) and then introduced into the patient (with, for example, diabetes). (sentientdevelopments.com)
  • In their new paper, Science author Woo Suk Hwang from Seoul National University in Seoul, Korea and colleagues replaced the nuclei from donated oocytes with nuclei from skin cells from male and female patients, ranging in age from 2 to 56, who had spinal cord injuries, juvenile diabetes and the genetic disease "congenital hypogamma-globulinemia. (scienceblog.com)
  • In August 2001, President George W. Bush announced that he would allow federal funding for about 60 existing stem cell lines created before this date. (cnn.com)
  • These cell lines will enable the study of human disease in cells in the laboratory. (scienceblog.com)
  • In laboratory culture, these cell lines displayed signs of immunological compatibility with the patients' cells, Science authors reported. (scienceblog.com)
  • The stem cell lines produced from patients with disease will likely display characteristics of the disease, so they will probably not be appropriate for direct use in treating patients. (scienceblog.com)
  • Other improvements over the last paper include the reduced use of animal products in laboratory procedures and better evidence that the cell lines matched the patients' cells and did not have a parthenogenetic origin, where unfertilized eggs can divide on their own. (scienceblog.com)
  • Deliver 2 clonally expanded mycoplasma free iPSC lines (15 x 300k cells). (lu.se)
  • In November 2010, William Caldwell, CEO of Advanced Cell Technology, said the FDA had granted approval for his company to start a clinical trial using cells grown from human embryonic stem cells. (cnn.com)

  • basic characterization, including cell authentication (STR), undifferentiated state (FACS) and molecular karyotyping. (lu.se)
  • Physicians could also extract DNA from the person who is going to receive the cellular transplant - creating a patient-specific treatment - though that would end up being far more expensive than drawing from a library of ready-made cells. (usf.edu)
  • Could a Hair Transplant Today Cause Problems for Any Potential Cure or Cloning in the Future? (baldingblog.com)
  • Molly received a stem cell transplant from stem cells from Adam's umbilical cord. (cnn.com)
  • They are still developing and they have the potential to become any of the major specialized cell types within that organ. (cbc.ca)
  • Similarly, when the fertilized egg divides from two cells into four cells, each of these four cells has the potential to individually form a human fetus. (jcpa.org)
  • However, by the time the fertilized egg divides into 8 or 16 cells something changes and each respective cell, if separated, no longer has the potential to create a fetus. (jcpa.org)
  • Stem cells have the potential to become many kinds of cells and can renew themselves through cell division. (cnn.com)
  • But, he adds, the study also demonstrates the potential for using human-stem-cell-derived tissues to model other disorders, if cell growth can be controlled more reliably. (cbc-network.org)
