How hard is it to find stem cells in the body?

I am doing a paper on stem cells and I have to know how hard it is to find them in the human body. I know that they can be found in bone marrow and the umbilical cord but how hard would it be to find one that has not been turned into any other cell yet?

    Stem cells can be taken from:

    • Embryos

    • Umbilical cords

    • The placenta

    • Amniotic fluid

    • Adult tissues and organs including bone marrow, fat from liposuction, regions of the nose and even dead bodies up to 20 hours after death

    Catholics believe that life is a sacred gift from God and needs to be treated with all human dignity from the moment of conception to the point of natural death.

    For this reason, the destruction of living human embryos to harvest embryonic stem cells is immoral.

    • The end never justifies the means

    • A moral good can never come from a moral evil

    Here are just a few of the common myths about Stem Cell Research:

    Myth: Stem cells can only come from embryos.

    Truth: Stem cells can be taken from:

    • Umbilical cords

    • The placenta

    • Amniotic fluid

    • Adult tissues and organs including bone marrow, fat from liposuction, regions of the nose and even dead bodies up to 20 hours after death

    Myth: The Catholic Church is against stem cell research.

    Truth: The Catholic Church approves three of the four types of stem cell research:

    • Against Embryonic stem cells

    • For Embryonic germ cells (from miscarriages)

    • For Umbilical cord stem cells

    • For Adult stem cells

    Myth: Embryonic stem cell research has the greatest promise

    Fact: Up to now, no human being has ever been cured of a disease using embryonic stem cells. Adult stem cells, on the other hand, have already cured thousands. There is the example of the use of bone marrow cells from the hipbone to repair scar tissue on the heart after heart attacks. Research using adult cells is 20-30 years ahead of embryonic stem cells and holds greater promise.

    Based on the “The Ten Great Myths in the Debate Over Stem Cell Research” by Tadeusz Pacholczyk, Ph.D. http://www.ncbcenter.org/10Myths.pdf

    Adult stem cells are currently used for the medical treatment of:

    • Anemias

    • Cancers (multiple types)

    • Child Leukemias

    • Cornea Regeneration

    • Crohn´s Disease

    • Diabetes, Type I

    • Heart Disease, Acute & Chronic

    • Krabbe Leukodystrophy

    • Liver Cirrhosis

    • Lupus

    • Lymphomas

    • Myelomas

    • Multiple Sclerosis

    • Paralysis

    • Osteopetrosis

    • Parkinson´s Disease

    • Rheumatoid Arthritis

    • Severe Combined Immunodeficiency Syndrome

    • Sickle Cell Anemia

    • Spinal Cord Injury

    • Stroke

    • Systemic Vasculitis

    • and more

    Embryonic stem cells (the ones that turn into anything) come from embryos. That is the first stage of a fetus, though it is not a fetus yet.

    The embryos are created in the lab for women who are going through IVF (eggs are surgically harvested from woman - several cycles of hormones first, sperm from male ejaculate, microscope tiny needle and petri dish... later several at a time are inserted each menstrual cycle hoping that eventuall one will implant into the uterus resulting in a healthy full term pregnancy.

    But it takes several cycles, these women *usually* have had diffuclty getting pregant before (other reaons are designer babies, savior siblings, or to select embryos that dont have negative genetics due to inheritence of the parents, also some surrogate parents, or women who need donor eggs), so as many eggs that can be harvested can be.

    They cant reliably store eggs alone, so they create embryos right away, and then freeze them.

    When the woman is done trying to conceive, most have their embryos destryoed. Other options are saving them at a high expense, or donating them. But for varios reasons most dont.

    Embryonic stem cell research (human, anyways) was born out of the research from the embryos that were saved instead discarded. A lot of break throughs other than main stream embryonic stem cell research has come from it. A lot of women donate instead of destroy because it gives the life meaning instead of just trashed.

    The embryos are used at about 5 days old. They have a fraction of the number of skin cells you shed in a second. They have no organ formation, no heart, no brain, no head, body, arms, legs, no cns, no consioness, no sense of pain or any other emotion.

    They debate is over whether or not it is morally or ethically right to take the lives of embryos for the research.

    I say yes. Especially if its ok to incinerate them in biowaste after women are done using them to get pregnant, not to mention the embryos that die after insertion in the uterus but never implant (it takes *several* cycles for it to work, generally 2-3 embryos per cycle, but some go upward of 5-8). Especially if this research can lead to other medical break throughs.

    A criticism is that it has no human treatments. After about 15 years, you wouldnt expect for it to. Almost every med on the market spent 20 or more years before it was available pubically. What a lot of people dont realize is that a lot of the meds only tested for a few years are essentially old meds that have been slightly tweaked to get a new pantent.

    Oh, but adult stem cells can treat 70-100 diseases. Yes. Over 95% of them use the same treatment. A bone marrow transplant, which is actually transplantling the blood stem cells that make up the bone marrow (the same type of stem cells are also in the circulating blood as a type of white blood cell, and the cord blood you mentioned, and all 3 can be used in the transplant).

    From leukemias, lymphomas, myleomas, non cancerous blood diseases, auto immune diseases, help treat other cancers or repair damage to bone marrow/immune system from treatment of other cancers or diseases, may be used in the future treatment/cure of hiv/aids... counting all that youve got 60-85 diseases.

    This treatment took 50 years to develop after they new bone marrow was stem cells - though that term wasnt used.

    Slightly over 50 years from the time it was publically available, 2/3 of the ppl that need it cant get it because they dont have a matched donor and cant use their own stem cells, regardless of banked cord blood, peripheral blood or bone marrow.

    About 1/3 of those left have no way to afford what turns out to be a multi million dollar treatment because they dont have insurance (3 months in a hospital icu, chemo, radiation, tons of meds, min year off work but avg is 2-3, no one else will ever medically you again, and so on).

    Close to half (its somewhere like 48%) that make it to the transplant die before they find out if it even worked because its *that* dangerous.

    Of the half that make it through the transplant, 1/3 die from complications in 5 years, another 1/3 in 10.

    Complication list is HUGE, both short term and long term. High dose chemo and radiation is used in the transplant. The boasting point of adult stem cells is that they dont cause cancer. No, the the chemo and radiation sure do. They put the patient at risk at nearly every single thing it treats, plus about a dozen more.

    Less serious, fertility, graft vs host disease, a life long of medications, complications from fertility and estrogen loss, cataracs, weight gain from all the steroids to treat gvhd, glaucoma, and the list goes on.
