  • In a recent report,95 human ES cells were shown to express low levels of MHC class I proteins. (vumc.org)
  • Previous work showed that stem cells, including HSCs, synthesize proteins much slower than other cell types, prioritizing quality over quantity. (scitechdaily.com)
  • This helps them make fewer mistakes in the process, as misfolded proteins can become toxic to cells if allowed to build up. (scitechdaily.com)
  • In most cells, damaged or misfolded proteins get individually tagged for disposal. (scitechdaily.com)
  • This left the team puzzled: if getting rid of damaged proteins is so important to stem cells, why is the proteasome less active? (scitechdaily.com)
  • A main advantage of the proteasome method is that it breaks proteins down immediately, producing amino acids that the cell can reuse to build new proteins. (scitechdaily.com)
  • But stem cells are less interested in building new proteins. (scitechdaily.com)
  • Thus the authors suggest that by storing a collection of damaged proteins in one place, stem cells may be creating their own cache of resources that can be used at a later time when they are actually needed, such as after an injury or when it is time to regenerate. (scitechdaily.com)
  • The authors suggest that stem cells' inability to efficiently destroy misfolded proteins during aging is likely a key contributing factor to their declining function and the resulting age-related disorders. (scitechdaily.com)

  • It will be difficult to determine whether Geron s injected cells had any real effect. (lifenews.com)
