  • Learn about the science of stem cells and how these incredible, transforming cells could lead to personalized medicine for individual bodies.
    --
    Is personalized medicine for individual bodies in our future? Possibly -- with the use of stem cells, undifferentiated cells with the power to become any tissue in our bodies. Craig A. Kohn describes the role of these incredible, transforming cells and how scientists are harnessing their medical potential.

      The whole body regenerates itself, but not so well these days. They should be telling us why our bodies aren't performing as well as they could be, not what 'scientists' are doing to help. These same 'scientists' discovered GcMaf back in 1994 and it has been suppressed by all gov'ts since then. They are not performing as they should be due to nagalese which we get from vaccinations. Nagalese cripples our own GcMaf production, that's why it's in vaccines, so you keep having to visit your doctors for more 'disease management', otherwise known as being fleeced by Big Pharma.

    Hello all! A couple quick responses to some valid questions:
    -Currently most stem cell therapies are based on tissue-specific (or "adult") stem cells. The treatments are very limited in what they can do (hence the interest in other kinds of cells).
    -Tissue made from embryonic pluripotent stem cells does face the risk of rejection by your body. This is why there is so much interest in induced pluripotent cells, which would come from your body but have the capabilities of embryonic stem cells.

    Love the graphics and the explanation is very clear...but....and this is a big but here... you skipped completely over the fact that you can collect non-controversial stem cells from cord blood at birth without causing harm to the mother or child. You mention embryonic but this is a far more controversial source of stem cells. Why not just use something that we would otherwise throw away? Let's use the cord blood collected just after the birth of a child. Give life twice. Save the cord.

    2:15 To add to that:
    For Leukemia, the curative effect of stem cell transplants is actually due to the GvL effect, or Graft versus Leukemia effect. In other words, it's an IMMUNE-based response where the new cells you received (LTCD8, NK cells) are literally directed against your cancerous cells, thus curing you of Leukemia.
    (or at least that's me summarizing what I understood from today's lesson. I really like your video btw)

    Embryonic stem cells aren't necessarily aborted babies with regards to IVF. If a couple are not able to have a baby they can obtain the necessary requirements for life from donors. The sperms and eggs are brought together in a lab where they form embryos, but say for example 5 embryos were made but the doctor only implants 2 into a surrogate (or the mother) and the doctor freezes the other 3. She falls pregant and gives birth. Now maybe the mother wants more children then she can use the remaining 3 embryos to be implanted in her and can fall pregnant. BUT the mother may not want to have any more children hence she is given the option to maybe donate the embryos to another couple who wish to have a baby but can't OR donate them to science - in this case stem cell research. This is the reason why stem cells is such a controversial topic because the remaining embryos are more or less unborn babies and it may go against the grain of several religions.
