Can anyone explain to me what the "Fetal Tissue" is?
406196
It is tissue (i.e. cells) obtained from foetuses, often used in medical experiments.

Where do you come up with this stuff? LOL, feces fetus?

You got me going over this, so I've been all over the world looking for an answer\n\nWhat is behind my belly button?\n\nAccording to the punch line of an old joke: "If you unscrew your belly button, your bottom falls off." In reality, the umbilical vein comes from the afterbirth or placenta, which carries blood enriched with oxygen and nutrients to the developing baby.\n\nThe umbilical vein runs from the navel to the fetal liver and through a bypass vessel (the ducted venosus) to the fetal heart. After birth, the umbilical vein remains open for a time, but soon afterwards it closes and shrivels up to become a fibrous cord. It crosses the abdominal cavity in a fold of the abdominal wall lining forming the round ligament (the ligamentum teres). Sometimes things don't close as they should and an umbilical hernia develops.\n\nmeaning\n\nOur belly button does not heal over because there is nothing between it and our stomach except a few thin layers of skin

This is the tissue that is created to connect the mother and fetus. About a week after conception, the placenta begins to secrete the hormone human chorionic gonadotrophin (hCG). This hormone prolongs the lifespan of the corpus luteum as well as stimulates production of progesterone. During pregnancy, the placenta transports nourishment and takes away waste. Under normal circumstances, your blood does not flow directly into the baby, nor does your baby's blood enter your bloodstream. Among many other tasks, the placenta serves as a blood filter, keeping your blood on one side and that of your baby on the other. Toxins and other substances, however, can pass through the membrane - so be careful what you ingest and breathe!

Foramen Ovale\n\nThe foramen ovale remains open during fetal development to allow blood from the venous system to bypass the lungs and go to the systemic circulation. This is because prior to birth, the oxygenation of the blood is via the placenta and not the lungs. A layer of tissue begins to cover the foramen ovale during fetal development, and will close it completely soon after birth. After birth, the pressure in the pulmonary circulation drops, and the foramen ovale closes. In approximately 30% of adults the foramen ovale does not seal over.

"The umbilical cord is the life-line that attaches the placenta to the fetus. The umbilical cord is made up of three blood vessels: two smaller arteries which carry blood to the placenta and a larger vein which returns blood to the fetus."\n\nSince the umbilical cord only houses arteries, it wouldn't look like much on the inside.  \nIn fact, surgeons often operate through the belly button to minimize scaring for the patient...so it can't be complicated behind it...I assume it's just a scar there, and once the arteries were no long needed, they emptied and that was all.

As Keri B said, it has a lot to do with exposure to the elements...previous to this, the fetus had been suspended in amniotic fluid, which is a pretty neutral environment. Contact with the outside world is harsh on the body, and dry skin is frequently a problem in healthy newborns.\n\nSpecifically, in the case of a stillborn, there isn't any blood flow to the skin, which makes it more prone to peeling/tearing. In essence, it's a part of decomposition.\n\nAlso, I have to confess, I'm really curious as to what brought this question up...

Actually I think you're thinking on the right lines. I'm gonna do some reaserch and get back to you.\n\n\nDoctors 'find dead foetus in boy'\nDoctors in Bangladesh say they have removed a long-dead foetus from the abdomen of a teenage boy who was complaining of stomach pains.\n\nThey said the foetus would have become the boy's twin had it grown normally in their mother's womb.\n\nThey said it was a case of an extremely rare condition where two foetuses are conceived as conjoined twins but one absorbs the other.\n\nIn 2003 Kazakhstan doctors removed a foetus from a seven-year-old boy.\n\nLimbs developed\n\nSixteen-year-old Abu Raihan was admitted to the Bangabandhu Medical University hospital in the capital, Dhaka on Saturday.\n\n"After the operation we found a dead foetus weighing two kilograms (4.5lbs) in his abdomen," Doctor MA Mazid said, the AFP news agency reports.\n\n"Apart from the head, all other limbs of the baby were developed."\n\nThe condition is known as "foetus in foeto", or inclusion twin.\n\n"In this case the foetus of the baby entered into the foetus of the boy and continued to grow like a tumour in the boy's abdomen," gynaecology specialists Nurun Nahar said.\n\nHundreds of curious locals flocked to the hospital on hearing a rumour that a boy had given birth to a baby.\n\nIn April, 2003, doctors at Chimkent Children's Hospital in Kazakhstan discovered the dead foetus of a twin brother when operating on a seven-year-old boy.\n\nThe foetus had developed into a tumour but was found to have hair, nails and bones.

Fetuses develop deeper brain folds as they get closer to birth:\n\n"If one looks at the brain of the developing infant in utero, it's really quite smooth, but during the last 12 weeks of prenatal development the brain folds in on itself," says Michael Rivkin of the department of neurology at Children's Hospital in Boston, Mass. "By the end of the pregnancy the surface of the infant brain consists of a landscape of hills and valleys, technically referred to as gyri and sulci. By the time the infant is born, its brain looks like the brain of an older child or young adult."\n\n(see refererence).\n\nThe folds also might get deeper with age, but I was not able to find much information on that without doing an extensive search.

It is an accumulation of stray hairs, clothing fibers, and dead skin cells in the belly button. For some more info, check out the link.

A stem cell is a cell that hasn't been differentiated yet.  Meaning it is not yet a skin, brain, liver, heart, muscle, etc. cell.  They are mostly found in embryos because they obviously are still developing so there is a large amount of stem cells there.  Adults also have stem cells in our bone marrow because that is the site of blood cell synthesis (we are constantly making new blood cells).  \nStem cell research is important in finding out how to differentiate cells into what we want.  This would be nice for making new organs for transplants or even new skin for grafts.  I'm not sure if we can use the stem cells from adults or not, but as far as i know, in the US we are not allowed to use new stem cells for research, only the ones we already have. \nIn my opinion, since there are abortions already being performed (no matter what your opinion of it, it's being done) , instead of just wasting the embryo/fetus, we should at least put it to good use and use it for research to help others.

I have to agree with you.  It is an abominable practice.  I find it comparable to the Japanese tradition of drowning newborns just because they were not the prefered sex.  \nAlso, fetal stem cell research has been going on for many years, with no promising results at all.  How can anyone argue that any of these "lofty goals" are ever going to materialize?  I have no problem with research involving adult stem cell, which by the way, is showing much more promise.

I am sorry to hear that. The word ECTOMESENCHYMAL refers only to the origin of the proliferating cells. That is, when the embryo is formed, all its future cells come from one of 3 different layers. The MESENCHYMA is the type of tissue you could, simplistically, call non-visceral. That is, tissue that doesn't form glands or organs. It forms muscle, connective tissue, and so on.\nSo an ECTOMESENCHYMAL TUMOR only means that the cells (I don't really know if, in this case, they are benign or malignant) that are proliferating, come from this kind of tissues.\n\nBy the way, "onewhitewhiskar": IT DOESN'T MEAN STEM-CELL TREATMENT, AT ALL. Never make suppositions when talking abput someone else's health. It's unhealthy.

Good for N. Dakota! I can only hope that the rest of this nation comes to it"s senses soon also.Life begins when God breaths the soul into the child. I beleive that is at the moment of conception. To abort a baby while it's in it's mothers womb is nothing short of murder. When that dredful day of roe v wade came, and the decision was made, we did not have the technology we do now. We now can see in detail how alive this baby is.I know this is a hot topic, and both sides feel very strongly about their positions. I however cannot ignore the evidance that we can so clearly see, and say that this is a lifeless blob growing inside it's mother. No, it's a child alive and growing. God forgive us for all the murders we have done. Because it's legal dos not make it right. When it was illegal it was done and it was wrong, and now that it is legal it is still WRONG!

Microchimerism\n\nIn Greek mythology, a chimera is a fire-breathing monster with the head of a lion, the body of a goat, and the tail of a serpent. In biology, a chimera is an organism consisting of tissues whose cells derive from two or more genetic sources. An apple tree, for example, can include grafts that enable it to produce a variety of apple types. In humans, such genetic mosaics reflect specific, intimate circumstances. The phenomenon is termed microchimerism because a one-cell population is typically much smaller than the other.\n\nAn organ transplant is an unnatural procedure that suddenly deposits many cells from one individual into another whose own organ has failed. It is similar to grafting in plants, and in fact, if the donor tissue reacts against the recipient's body, the condition is termed "graft-versus-host disease" (GVHD). When a transplant works, a peaceful co-existence evolves as recipient cells infiltrate graft tissue, and perhaps also as the transplanted cells alter their gene expression to modify their cell surfaces so that they are less likely to provoke the recipient's immune system. Microchimerism in transplant medicine does not refer to the transplanted material, but to small numbers of donor cells found outside the region of the transplant. For example, following transplantation of a liver, lymphoid and dendritic cells of the immune system often turn up outside of the liver, but with cell surfaces that match those of the donor, not the recipient.

To say uterus will be too undetailed. Fetal development occurs in the endometrium of the uterus, which is the uterine lining. \n\nBoth the placenta and the amniotic sac originates from the endometrium, which also facilitates diffusion of nutrients btw the mom and the fetus thru the umbilical cord. hope that helped
