  • Cloning has been proposed as a means of reviving extinct species. (wikipedia.org)
  • depictions commonly involve themes related to identity, the recreation of historical figures or extinct species, or cloning for exploitation (i.e. cloning soldiers for warfare). (wikipedia.org)
  • They can differentiate into all types of specialized cells in the body. (healthline.com)
  • The main difference between the two is that natural cloning does not involve any human intervention, whereas artificial cloning is a genetic engineering technique. (wikipedia.org)
  • 1. Cloning is an umbrella term traditionally used to describe different processes for duplicating biological material. (who.int)
  • Although, there were a great immense sum of tries he hardly ever fully manages to obtain replicated an adult specimen. (mabuty.com)
  • Adult stem cells have a misleading name, because they are also found in infants and children. (healthline.com)
  • Adult stem cells don't present any ethical problems. (healthline.com)
  • During the differentiation process from hematopoietic progenitor cells, chromosomes in the cell nucleus aggregate and the cell becomes a mature erythrocyte by subsequently losing this nucleus (enucleation). (sciencedaily.com)
  • According to rough calculations, the amount of culture medium needed to produce enough erythrocytes for a normal transfusion pack (containing one trillion units) is 1,000 -- 2,000 liters when using direct differentiation from undifferentiated iPS cells, whereas 50-100 liters is sufficient with the newly developed method. (sciencedaily.com)
  • WHA50.37, which states "the use of cloning for the replication of human individuals is ethically unacceptable and contrary to human integrity and morality. (who.int)
  • Hematopoietic progenitor cells, however, still have self-replication ability, and if the factors involved in this self-replication could be identified, it might become possible to induce virtually unlimited replication of progenitor cells. (sciencedaily.com)
  • The research showed that an increase in the expression of the c-MYC gene led to an enhancement of the replication ability of erythrocyte progenitor cells. (sciencedaily.com)
  • It was also found that the expression of the BCL-XL gene was higher during the maturation process of erythrocyte progenitor cells than during their replication process. (sciencedaily.com)
  • Topics covered will include cell membrane structure and function, metabolism, cell motility and division, genome structure and replication, the regulation of gene expression and protein production, genotype to phenotype relationship, and basic principles of inheritance. (middlebury.edu)
  • From his research on immunology, Good was able to perform the first successful allogeneic (donor and recipient are unrelated) bone marrow transplant. (asu.edu)
  • It has earlier also been demonstrated that the bacteriophage Mu is silently transferred to recipient cells by these donor strains, and both occurrences are very likely to lead to mutations within the recipient DNA. (bvsalud.org)
