Old Stems Cells Young Again — Via Vampirism 109

Posted by ScuttleMonkey from the ecstatic-twilight-fans dept.
pdragon04 writes to tell us that in recent tests a Howard Hughes Medical Institute team has found that through exposure to "young" blood cells, bone marrow stem cells start to act young again as well. "The researchers have not yet isolated the blood-borne factors that can switch old stem cells back to a more youthful state, but their results are consistent with other recent studies that show stem-cell aging may be reversible. Together those results suggest that it might one day be possible to boost the practical lifespan of stem cells, and thereby increase the body’s resistance to disease and age-related degeneration."

    They were using older and diabetic mice for their tests.

    I can't help but wonder if this discovery may have some effect on diabetes treatments in the future. For diabetics who still have some pancreatic function, and aren't wholly dependent on pills, maybe the results found from this research could help them.

    As for those who are dependent on pills, needles, and the like, I could wonder what it would do for them.

    The article didn't really clarify what happened with the diabetes in the affected test subjects, though, so I lack that answer.

      I think you meant dependent on injections. The pills in question would be to either boost insulin sensitivity (Useful for type 1 (no pancreatic function) and 2 (insufficient pancreatic function)) or boost pancreatic function (only useful for type 2). Injections provide insulin directly (required in type 1, used in type 2 if other options are insufficient or can't be used for other reasons).

        I'm a type 2 diabetic. I only use pills, diet, and exercise to treat my symptoms, since the insulin I was taking was causing me to bottom out (50-60 mg/dL or lower). I would love something that would drop the need for (up to) 2.5 gigantic pills out of my daily regimen (especially given the side-effects (of which my gut would thank me to avoid) of Metformin).

    Except acting young again, does mean they stem cells will have lost any genetic damage, that occurred though aging. Perphaps some day though medicine will be able to produce truely young stem cells, but that would require checking that the DNA hasn't mutated from the orignal young cell line.

    • Except acting young again, does mean they stem cells will have lost any genetic damage, that occurred though aging. Perphaps some day though medicine will be able to produce truely young stem cells, but that would require checking that the DNA hasn't mutated from the orignal young cell line

      The current thinking in the field is that stem cells are generally more resistant to DNA damage than many other types of cells. A lot of damage comes from when the cell replicates it's DNA in preparation for division. The "textbook" stem cell don't seem to divide very often, instead they divide once to make transit amplifying cells, which divide like mad for a short period, making cells which will eventually mature and then not divide again. Why exactly older stem cells don't replentish the immune system

    • This is right on the money. There is a reason that stem cells become old, they become senescent and decrease or stop their division to protect against cancer. Cellular senescence can be induced by oncogenes, or bypassed by introducing the factors found in this study.

      Knocking out tumor-suppressing genes has been shown to decrease aging while at the same time increase tumor incidence.

      Call me the day cancer is cured, that's the day these discoveries can be beneficial against aging.

      Jokes about Howard Hughes and blood sucking seem perfectly reasonable.

      Okay for the serious discussion. Obviously there's some chemical trigger involved to so the cells are responding more like young cells. It seems likely a drug could be developed that could delay age related disease. Immortality is likely an impossibility but delaying aging another decade or two would be massive. I'm starting to feel the effects of aging so getting ten years back even if it didn't extend life would be huge to me personally

      Okay, but it's going to be a while before that's anything other than academic, and it isn't sped up by the results here. The present study has preliminary results on signaling needed to make mouse blood stem cells divide more as they did when they were younger. One day we may be able to use this knowledge to improve immune function in seniors. Cell signaling tends to be very specific to the cell type, the context. We are most likely not going to find that these same signals make all other stem cells act

  • Although they try to match size, then relative age, sometimes out of expediency a recipient must accept a donor a decade, two, or even three decades older than themselves. Would these organs age at the donor's rate or recipient's rate? I'm guessing the answer is "in between". Depending on the tissue, the donor cells may be slowly replaced by host stem cells over the decades and become more host-like. Heart and muscle has a slow turnover rate of one percent a year. So hearts are never fully converted. Som
    • My guess is that the organ would most likely continue to age at the donor's rate and any "turnover" would be too slow to make any appreciable difference. I found this article about kidney transplants. From the extract, it basically says the age-matching helps increase the chances of survival for young recipients. http://jasn.asnjournals.org/cgi/content/full/15/4/1086 [asnjournals.org]

  • One painless, uncontroversial source of both young blood and stem cells is (or was) your umbilical cord blood. This is usually thrown away. Collecting it after a baby is born is trivially easy. The material is easy to preserve for decades. Costs are mostly related to storage & record-keeping.

Although it's common in modern childbirth to cut the cord as soon as possible, it's very very bad practice. Your opinion is not shared by modern obstetricians. In any case there will always be some blood retained in the veins of the umbilical cord that would otherwise go to waste.
