How does Human Embryonic Stem Cells works on Paraplegia?
550150
Well , you see adult human neyron , that is barin cells have no capacity to regenrate and develop , so with paraplegia some cells have died and are no longer part of cicuit , the circuit has breaken dwon,  so when u infuse these human embryonic stem cells, these cells like embryonic cells have the capacity to divide , develop , and regenerate the circuits , this was re establishing the network which has been disturbed , reverst back to work.

It may never happen, frankly; a lot depends on the work being done on isolating autologous stem cells from this or that tissue; apparently there are viable stem cells that can be harvested from bone marrow, and possibly from the skin.  If that comes to fruition, embryonic stem cells won't be needed.\n\nOf course, if we could ever figure out how to dedifferentiate cells (theoretically possible, but not yet demonstrated), then redifferentiate them, the whole field would be dramatically altered.  I'm figuring that the autologous stemcells will be available first...\n\nAlso, not all of the diseases targeted are necessarily dreadful, nor are all dreadful diseases amenable to stem cell solutions.

Stem cells don't come from babies, they come from blastocysts.\n\n"Embryonic" stem cells is actually a misnomer. These cells come from blastocysts. which are developmentally younger than embryos.\n\nStem cells are derived from blastocysts that are left over after couples have had children using in vitro fertilization. For couples using in vitro fertilization, the woman has eggs harvested, which are then fertilized by sperm in a dish in the clinic. Eggs that are successfully fertilized are allowed to divide for 3-6 days, forming tiny balls of a 100 or so cells called blastocysts. These are frozen, and when the couple is ready, a few of these are implanted in the woman's womb.\n\nAfter the couple has conceived, they must decide what to do with the left over blastocysts. Some couples pay to keep their remaining blastocysts frozen, but most left over blastocysts are simply discarded! These discarded blastocysts, numbering in the hundreds of thousands, could be used to derive stem cells. The lines that are approved by the Federal government were created when couples donated their unwanted frozen embryos to research.\n\nThe blastocysts are like tennis balls, solid on the outside, but hollow in the middle. Stem cells are found in a little lump inside that hollow ball. Researchers have found a way to crack the ball in half and remove the stem cells.\n\nStems cells removed from the hollow ball can never develop into a human. The hollow ball contains the instructions or blue print to create a human from the stem cells. Without the instructions, a human can never form.\n\nOnce the stem cells are removed and placed in a dish in the lab, they continue to make exact copies of themselves, called daughter cells. They will only make exact copies of themselves and nothing else until a researcher adds different chemicals, or molecular signals, that tell the stem cells to become something else. Once we understand what makes them become what ever cell type, be it heart, pancreas, liver, or spinal cells, we have exquisite control over the repair process, being able to replace the cell type we want with more of the tissue derived from stem cells.

You are essentially correct in your rememberance.  Since they can't repair the spinal cord yet, the operation would only be useful in the case of people who already have substantial paralysis.

bmps can be used to stimulate stem cells to differentiate along certain lineages (osteogenesis for example), and can also be used to prevent stimulation into specific cell types (for example embryonic cells into neural)

There are processes of regeneration going on, but getting cells to specifically differentiate to take on those roles is still in its infancy. It also depends on how the brain was damaged and what parts were damaged. Stem cells are omnipotent which means that they can differentiate into any kind of cell, but a culture is very hard to maintain and the success rate of transplant is still very low.

the best any embryonic stem cells have achieved so far is tumers\nall succesfull so far have been from, adult stem cells and placental stem cells\nthe system of harvesting the eggs from wopman has later dammages caused by the extra hormones pumped into the body of the usually young girl\nall the above are moral as well as physical damaging\nby the koran life begins with the first clot of blood ,so natural harvested may not be sinfull but its the process of harvesting that is the bigger danger\nif science is so clever let them make thioer own stem cells \nbut science cant even make a single cell \nlet that be a sign for the creationists\ntrust man or trust science fraud ,its about the cash they can get from govt for faulse hopes and lies

practicaly anithing!! Stem cells can replicate themselves or make any type of cell required to build an organism.

Thats all I could find. Hope it helps.\n\n\nhttp://www.cfcc.cc.fl.us/news/archive/stemcells102705.htm

There isn't one.  No one tries to argue against non-embryonic stem cell research.  Unfortunately, many people don't know there it exists.  This is unfortunate because ALL successful stem cell research to date has involved non-embryonic stem cells.  If most people understood that, the debate would go away.

You should visit www.geron.com, it is the website of the top stem cell company in the U.S.  It has a great deal of information about what they have been doing in that field.

What kind of stem cell research? Embryonic stem cells come from unborn babies, which means you have to kill the most innocent and most defenseless of human life to get the cells. This is what the liberals want to do to increase the number of abortioins in the US and the world. There is no evidence that this type of cell research is going to produce anything of value. If it had any promise, investors would be lining up to put money into it. But they aren't, so the pro-aborts want government (that means "your money") to fund the research.\n\nOn the other hand, adult stem cell research has yielded incredible results. But you can't kill an adult, so the libs aren't interested in this type of research...

Stem cell research: There are two basic types:\n \nDefinition of a stem cell   \n\nA stem cell is a "generic" cell that can make exact copies of itself indefinitely. In addition, a stem cell has the ability to produce specialized cells for various tissues in the body -- such as heart muscle, brain tissue, and liver tissue. Scientists are able to maintain stem cells forever, developing them into specialized cells as needed.\n\nThere are two basic types:\n\nEmbryonic stem cells - these are obtained from either aborted fetuses or fertilized eggs that are left over from in vitro fertilization (IVF). They are useful for medical and research purposes because they can produce cells for almost every tissue in the body. \n\nAdult stem cells - these are not as versatile for research purposes because they are specific to certain cell types, such as blood, intestines, skin, and muscle. The term "adult stem cell" may be misleading because both children and adults have them. \n\nIn August 2001, President George W. Bush approved limited federal funding for stem cell research. While stem cell research has the potential to provide major medical advances, including cures for many diseases, stem cell research is controversial.\n\nPotential uses for stem cells \n\nThere are many areas in medicine where stem cell research could have a significant impact. For example, there are a variety of diseases and injuries in which a patient's cells or tissues are destroyed and must be replaced by tissue or organ transplants. Stem cells may be able to generate brand new tissue in these cases, and even cure diseases for which currently there is no adequate therapy. Diseases that could see revolutionary advances include Alzheimer's and Parkinson's disease, diabetes, spinal cord injury, heart disease, stroke, arthritis, cancer, and burns.\n\nStem cells could also be used to gain a better understanding of how genetics work in the early stages of cell development. This can help scientists understand why some cells develop abnormally and lead to medical problems such as birth defects and cancer. By understanding the genetic basis for cell development, scientists may learn how to prevent some of these diseases.\n\nFinally, stem cells may be useful in the testing and development of drugs. Because stem cells can be used to create unlimited amounts of specialized tissue, such as heart tissue, it may be possible to test how drugs react on these specialized tissues before trying the drugs on animals and human subjects. Drugs could be tested for effectiveness and side effects more rapidly.

Dr. Mengele:\n\nThe federal government provides LOTS of money for stem cell research RIGHT NOW.  It funds research for umbilical cord and adult stem cell research and for existing embryonic cell lines.\n\nWhat it doesn't do is support the murder of additional embryoes.  But as Dr. Mengele, you don't care about murdering people.  You just want to play god.

First of all, I'm pro-choice and I support embryonic stem cell research.\nSecond, it'd be impossible to get stem cells from an aborted fetus.  Embryonic stem cells come from embryos - hence the name.  The cells used  come from embryos that are less than a week old.  Older cells wouldn't work because embryonic stem cells are undifferentiated cells that haven't developed into specific adult cells yet.  So an older cell that has already developed would be useless for research purposes.

They have proven that the stem cells found in the cords at the time of delivery provide just as much genetic material and supply for testing and research. \n\nI think they should use those cells, and not those they collect from cultured embryos.\n\nThere is always a way to test and research that doesnt involve the use of lives without voices. Such as the unborn or animals. I think those should be sought after and explored.
