    … cells can also live a lifetime in her heart and mind.

    How can cells live in the mind?

    • Drew_Gehringer says:

      Assuming mind and brain are the same, it’s totally possible for cells to live in the brain.

      • Bodhipaksa says:

        You can have a brain without having a mind, so the two are not the same.

        • Jerril says:

          However we have yet to have a mind without a brain. Mind is a subset of brain, not an independent concept.

          Also known as “Why mind transfer devices won’t work without changing the targets brain structures.”

        • crash2parties says:

          Think, subset.  As in, you can have a brain without having a mind, but you cannot have a mind without having a brain.  Studies of damaged and manipulated brains have shown it exceedingly well.

      • jchack says:

        That is a lot to assume. Materialism is a popular view, not an established scientific fact. You sir are a neural chauvinist!

        • AnthonyC says:

          If the mind is *not* exclusively a product of the brain, then the brain is at least extremely important to the mind. The brain is where much information processing happens, where sensory information goes in, and where motor and metabolic commands go out. This means that the brain is part of the mind, and so a cell in the brain is also in the mind.

        • crash2parties says:

          Actually, it’s not a lot to assume, and it is an established fact.  Simplest example:  damage an area of the brain and record the behavioral and perceptive changes it produces in the subject’s “mind”.  It can get far, far more subtle than that gross example, too and yet still produce significant results (ie very strong, local magnetic fields affecting memory and mood in test subjects).

          • jchack says:

            My answer to both comments is that systemic dependency is not the same thing as material equality. Which was my subtle point at the top of this post.

  5. Long ago, before the existence of the vaccine, My mom’s B-antibodies and immune cells made mincemeat out of my liver.  I was born neon orange. As the second born, I was extremely lucky to not be dead.  Hurray! (I’m still not dead)

    • blueelm says:

      Haha! Same for me. My mom’s body tried to kill me. Now she has an auto-immune disease and her body is killing itself.   Maybe that’ s my fault :/ 

  6. chgoliz says:

    “One theory is that this “otherness” stimulates the mother’s immune system just enough to help keep malignant cells in check. The more fetal cells there are in a woman’s body, the less active are autoimmune conditions such as rheumatoid arthritis and multiple sclerosis.”

    No, actually.  Women are significantly more likely than men to develop auto-immune disorders, and research is suggesting that fetal cells are a likely part of the explanation.

    • If you read on, Jena mentions this as well. It sounds like there’s some mixed effect going on here. Fetal cells can cause auto-immune disorders, but they might also be protective in some cases, depending on factors we don’t understand very well yet. 

      • blueelm says:

        But don’t let that stop the positive spin on the gushy love fest of how great pregnancy is supposed to be for women. Because it’s not like there’s ever been an agenda surrounding that or anything. Like, ever. And it’s not like rampant slanting and emotionally loaded reads of scientific experiments have ever been used as propaganda. It sounds to me like it’s pretty biologically neutral, with consequences and benefits that really don’t merit saying much except “yep, something happens” right now.  Forgive my cynicism, if you can.

        • crash2parties says:

          I’ve only met one woman that had that pregnancy experience that matched how “great” it was supposed to be.  And truth be told, she’d somehow find bliss in being water tabled; she goes through the world with that facial expression people used to get while watching the Lawrence Welk Show.  You know, the glazed eyes & social “See, I’m happy” smile…  Can I join you in that cynicism?

          Pregnancy is a method mammals use to survive as a species and ensure genetic variation.  There’s lots of physical stress and discomfort and it’s dangerous, and there’s some emotional manipulation going on, like when bliss hormones and love hormones and all that are released.  But those are nature’s way of ensuring primates will have more than one single-child litter. 

          As social creatures we can help each other during difficult times, forming optimistic traditions and supportive memes.  But the (okay, I’ll say it:  somewhat paternalistic) meme of modern women preferring to be home, in the kitchen and pregnant as part of some Glorious role fulfillment or advertiser’s dream world diva has got to go.

          • dahlia says:

            i’ve never met anyone who had a baby who thought it was bliss.  i can’t say i’ve experienced any particular agenda in that regard — if anything, women LOVE to tell pregnancy war stories!  seriously, get a room of mothers going, it’s like bragging rights.  mine was uneventful and pleasant until the very end when all hell broke loose, here, sit down and i’ll tell you all about it ….

          • Antinous / Moderator says:

            I’ve had a couple of friends who loved being pregnant, but they weren’t the majority.

          • Sekino says:

            I’ve had a fantastic pregnancy, enjoyed it a lot more than I expected (partly because I had heard many more horror stories- and ubiquitous, dumb stereotypes- about it than happy ones)… and I’m about as far from being a Stepford wife as one can get (though I readily admit that labour was a total @#$%& bitch to me).

            I wish it were possible for women to either hate OR love something, or want OR not want something without getting singled out and judged either way.

    • Lacey D says:

      I agree… but… I have lupus and have never been pregnant- no, not even with a fetus that miscarried without me knowing it- I’m a lesbian. I would believe that in this case it is the cells working the other way- my mother’s cells, some of which may have been her mother’s cells, or those of her older sister, both of whom have/had lupus. This is all so fascinating. 

      • chgoliz says:

        Absolutely.  Auto-immune disorders run on one side of my family.  We’ve all had kids, and pregnancy definitely exacerbated our medical situations, but the family genes were already there, ready to be turned on.  Some of the new research on MS (one of the diseases that runs in the family) suggests that it’s a common virus that sets the genes off.  Pregnancy is a huge stressor, but there are plenty of others….genes are the real cornerstone.

    postpartum depression as parasitic infection?

  8. agthorn1981 says:

    “One theory is that this “otherness” stimulates the mother’s immune system just enough to help keep malignant cells in check. The more fetal cells there are in a woman’s body, the less active are autoimmune conditions such as rheumatoid arthritis and multiple sclerosis. These conditions improve during pregnancy and for some time afterward — suggesting that the mother’s immune system is more focused on attacking the “other,” not herself.”

    I wasn’t taught this in my cancer biology and immunology classes in grad school; rather, it was that pregnancy acts as a mild immunosuppressive to dial down the mother’s immune responses and protect the “foreign” fetus (one supporting piece of research at http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1782465/ and many more available with searching). It would also explain the improvement in the autoimmune diseases. This is why women who have previously had melanomas have higher rates of recurrence or metastasis during or immediately after pregnancy – because her immune system had previously held the cancer cells in check, but the immunosuppressive state of her pregnancy allowed the cells to proliferate and spread. Unfortunately it’s a lot less warm and fuzzy of a theory.

    • rattypilgrim says:

      And women who have never had children have a higher risk of breast cancer.  Women can’t win for losing or so it seems.

      • Diane says:

        According to  National Cancer Institute, the risk of a nulliparous woman having breast cancer is approximately the same as a woman with a first term birth around the age of 30.

        • rattypilgrim says:

          So, are you saying a woman who has her first birth when she’s 30  has the same risk of a woman who has never given birth? I mean, the story line for the past 30 years has been a woman is more likely to develop breast cancer if she has never had children. I think they even cited statistics from women in convents. Well, cold comfort all around, I’d say.

          • Antinous / Moderator says:

            Researchers looking at centuries of records in Britain determined that the fewer the children (including none), the longer the woman will live. And the older the woman when she has her first child, the longer she’ll live. Despite the breast cancer risk, having children still shortens your lifespan.

        • rattypilgrim says:

          P.S. Diane,  Nulliparous? Get real. Get human. Again, cold comfort. Yikes! Exactly what I mean. Get pregnant before 30 or suffer the consequences. I don’t buy it. What you are saying is for a woman’s best chance of a healthy life she has to have children. Why do these rules never apply to men?

          • Diane says:

            I am not saying anything. I am simply sharing the NCI’s claims. They also say that ” Breast cancer risk is transiently increased after a term pregnancy. (1).” I am not a scientist, I don’t know how much of that is true. As a 30 year old woman who chose to not have children,  I am definitely not saying that in order to have a healthy life  women should have children.  I’ve known women who had children early and still had breast cancer, so I think it’s more complicated than that. But again, this is just my experience. If I ended up having cancer because I did not procreate, I will deal with it, but I will never tell what women should do with their bodies.  (Forgive my grammar, English is my second language).

    • CAKTwo says:

      I was about to reply with this fact as well! It is NOT that the mother’s body is attacking the “other” better and ignoring the mother, it is that the mother’s body has lowered her ability to attack anything (sperm, fetus, the mother, common infections, etc). I have multiple sclerosis which I was diagnosed with years before my pregnancy (and which I most likely suffered from for the decade prior to diagnosis). Pregnancy was one of the best times of my life as my MS was in full remission. It remained so until about 4 months after pregnancy where my body flared up with one of the worst exacerbations I’ve ever had. Right now they are researching how to administer this immunosuppressive in a pill form to help decrease the effect of autoimmune diseases on the body.

  9. Mister44 says:

    I also find it fascinating how quick and varied our flora takes up residence in our guts, on our skin, etc. I always wondered if some bacteria was already in the gut from the mother at birth.

  10. artbyjcm says:

    It’s never lupus.

  11. phil koltko says:

    Any evidence that fetal stem cells can migrate to the ovaries and become ova? Seems like if this were possible, natural selection would favor it…

    • AnthonyC says:

      Strictly speaking, ova derived from fetal cells would share only half the mother’s genes, which is effectively a 50% genetic penalty for the mother compared to children produced from her own ova. So this would favor the father’s genes, not the mothers’ genes, and it would be in the mothers’ genes’ best interest to prevent this.

    • crash2parties says:

      The ova are already formed, if not yet matured at puberty and before.  So I’d say that unless the fetal stem cells can act as viruses and inject their DNA or swap like bacteria, the chances are pretty much zero.

  12. rattypilgrim says:

    Think about twins. Twins of opposite gender  share male and female hormones in vitreo. Maybe that’s the best of all possible worlds where a man and a women somehow have an understanding insight into the psyche of the other and are able to use that throughout their lives. I know whereof I speak.

  13. dahlia says:

    call me crazy, but i don’t find this particularly “squirm-worthy.”  i built it inside me, and little bits of it stayed, like sawdust.  sounds reasonable.  man, people are so squeamish in this day and age.

    • crash2parties says:

      Yes, but what if it was non-consensual and an egg fertilized and implanted?

      …his cells in you forever, in your brain, your heart…just when you thought the violation couldn’t possibly be greater, new information comes along.

      THIS is why Plan B is needed, over the counter &  to anyone who wants it.

      • dahlia says:

        of course it should be, but that’s a separate issue.  anyway, once the egg is fertilized and implanted, even if you dislodge it, this is claiming that a bit of cell stays behind, though i imagine it matters how long it was there.  it doesn’t strike me as an instantaneous thing.

        if this is how the body works, that’s how it works, whether it grosses you out or not.  let’s not get mystical or torture ourselves with deeper meaning.  it seems weird to me to get upset over what your body does and has always done since the beginning of time.  it’s like people who are horrified by menstruation or something, i don’t get it. 

        • crash2parties says:

          That’s a really good point, Dahlia.   I’m going to guess not many cells go back and forth until the placenta is developed and there’s a circulatory system to work with.

          It *is* the way the body works and there is *nothing* mystical about it other than what people choose to believe (in other words, there is an objective reality under it all).   Nor is it “gross”.  But I have trouble seeing it as “spiritual”, too.  It’s more…mechanical, I guess.  Spiritual is what’s in your head (as is deciding what’s gross and what’s beautiful).

          The only deeper meaning I was gleaning was in the special case of rape.  It struck me that what was explained in this report could make it emotionally far worse and really does point out the need for the choice I mentioned.

    after we are born, we die. this much is certain. 

  15. Mauricio Lozano says:

    I don’t understand how a cell can pass through the hematoencephalic barrier, is that possible now??

    • crash2parties says:

      Some T-cells can and do on a regular basis, seemingly as part of regular um, maintenance.  And, the BBB is much more permeable during inflammation.  *and* sometimes when some of those T-cells get inside, they incorrectly initiate an inflammation response and let other stuff in. 

  16. A. Ambrosini says:

    Augh, you’re being requoted (kottke) on details you got wrong.

    “In the first trimester, one out of every fifty thousand cells in her body are from her baby-to-be (this is how some noninvasive prenatal tests check for genetic disorders). In the second and third trimesters, the count is up to one out of every thousand maternal cells.”

    Your numbers are for the fraction of fetal cells in the BLOOD, which constitute a very small fraction of the total number of cells in the mother’s BODY.
