what is stem cell research?

Stem cells are obtained from Cord Blood.  This is the umbilical cord which connects the infant to his/her mother.  The cells found in this cord are able to differentiate into different types of cells for example, stem cells can grow into a pancreas or a liver, etc. with the stimulus of certain hormones. Stem cell research explores this idea and sees better ways of improving health for example, how can we grow these cells to regenerate nerves for people suffering from spinal cord injuries. It is ongoing but also controversial.

Researchers in Adelaide have found stem cells exist inside the teeth, in a discovery that could one day lead to teeth being regrown or repaired.\n\nResearchers say they have found a colony of stem cells existing in the core of a human tooth.\n\nStem cell biologist Stan Gronthos yesterday told a symposium on stem cell research that the goal is to store harvested dental stem cells in liquid nitrogen, ready for use to repair damaged or diseased teeth.\n\nBut he says there is a lot of work still to be done.\n\n"It's a complex organ and it's got many tissues associated with it so it's going to take a lot of study to actually try and form a living tooth in an animal," he said.\n\n"At the moment technology is at the stage where we can probably repair portions of the tooth."

Stem cells are primal undifferentiated cells which retain the ability to differentiate into other cell types. This ability allows them to act as a repair system for the body, replenishing other cells as long as the organism is alive.\n\nMedical researchers believe stem cell research has the potential to change the face of human disease by being used to repair specific tissues or to grow organs. Yet as government reports point out, "significant technical hurdles remain that will only be overcome through years of intensive research."[1]\n\nThe study of stem cells is attributed as beginning in the 1960s after research by Canadian scientists Ernest A. McCulloch and James E. Till.\n\nStem Cell Types\n\nPotency\nStem cells are categorized by potency, which specifies the ameliorative potential of the cell type.\n\nTotipotent stem cells are produced from the fusion of an egg and sperm cell. Cells produced by the first few divisions of the fertilized egg cell are also totipotent. These cells can grow into any type of cell without exception. \nPluripotent stem cells are the descendants of totipotent cells and can grow into any cell type except for totipotent stem cells. \nMultipotent stem cells can produce only cells of a closely related family of cells (e.g. blood cells such as red blood cells, white blood cells and platelets). \nUnipotent cells can produce only one cell type, but have the property of self-renewal which distinguishes them from non-stem cells. \n\nSources of stem cells\n\nStem cells are also categorized according to their source, as either adult, embryonic or cord blood stem cells.\n\nAdult stem cells are undifferentiated cells found among differentiated cells of a specific tissue and are mostly multipotent cells. They are already being used in treatments for over one hundred diseases and conditions. They are more accurately called somatic (Greek σωμα sōma = body) stem cells, because they need not come from adults but can also come from children or umbilical cords. Particularly interesting are adult stem cells termed "spore-like cells". They are present in all tissues (Vacanti, M. P., A. Roy, J. Cortiella, L. Bonassar, and C. A. Vacanti. 2001. "Identification and initial characterization of spore-like cells in adult mammals." J Cell Biochem 80:455–60.) and seem to survive long time periods and harsh conditions. \nEmbryonic stem cells are cultured cells obtained from the undifferentiated inner mass cells of an early stage human embryo (sometimes called a blastocyst, which is an embryo that is between 50 to 150 cells). Embryonic stem cell research is "thought to have much greater developmental potential than adult stem cells," according to the National Institutes of Health.[2] However, embryonic stem cell research is still in the basic research phase, as these stem cells were first isolated in 1998 (at least for humans), whereas adult stem cells have been studied since the 1960s.[3] Research with embryonic stem cells derived from humans is controversial because, in order to start a stem cell 'line' or lineage, it requires the destruction of a human embryo and/or therapeutic cloning, which some believe is a slippery slope to reproductive cloning and tantamount to the objectification of a potential human being. In an attempt to overcome these moral, political and ethical hurdles, medical researchers have been experimenting with alternative techniques of obtaining embryonic stem cells by extraction, which does not involve cloning and/or the destruction of a human embryo. \nCord blood stem cells are derived from the blood of the placenta and umbilical cord after birth. Since 1988 these cord blood stem cells have been used to treat Gunther's disease, Hunter syndrome, Hurler syndrome, Acute lymphocytic leukemia and many more problems occurring mostly in children. Umbilical cord blood use has become so common that there are now umbilical cord blood banks that accept dona

Cell division reproduces the same kind of cell.  Cell differentiation is, in embrionic development, the situation wherein cells split-off in different "directions" to become very different things (eg., skin, spleen,...etc.)\n     An editorial:  Stem cell research is investigating the ways that very basics cells (think "undecided") might be introduced and encouraged to grow into cells... organs... to correct some sort of desease or injury.  I think it's a good thing!

there are various stem cell lines but they are not all totipotent (meaning they can convert to any cell line in the body) most of them are in locations where constant renewal of cells are necessary like the lumen of the gut or the bone marrow or the reproductive tract. They are caller pluripotent (they can form multiple cell lines but not all) and are used in as i said repairng the organ as cells from that are worn out or simply die or ejaculated (blood and sperm or egg respectively)\n\nthey are also pretty useful in performing genomic assays in adult organisms to see how they react to injury or chemical stress

Several universities in Canada do stem cell research.  Probably most well known is the University of Toronto which maintains human embryonic stem cell lines.   Other Universities include:  Dalhousie, Univeristy of Calgary, Queens University, and many more.  For a more complete list, please see the Source link.

Allow me to address your questions in a different order than you have asked:\n\nFirst of all, there is a reason why it seems like they're saying stem cells might cure just about anything.  The reason is that it seems that way to scientists too!  Let's put it this way - given the right set of stimuli, we KNOW a stem cell can grow into any cell in your body.  We know this because that is what stem cells already do on their own.  The potential for medicine is staggering.\n\nImagine what repairing a car would be like if all you could use were whatever parts happened to be in the nearest junkyard.  You might be able to use duct tape to hold things together a little longer, or if you're lucky you'll have exactly the right part available, but otherwise mostly you're making do and hoping.  That's kind of where medicine is now with major problems.\n\nIf some of the promise of stem cells pan out, however, the potential exists that any time something goes wrong, doctors could produce a new part and replace the old one.  Like having a catalogue of custom car parts at your fingertips.  Lost your arm in a car accident?  Your pancreas stopped producing insulin and now you're diabetic?  You don't like that old, wrinkly skin you have and want something new?  NO PROBLEM.  (You can see, I hope, why that might make people excited)\n\nBut it's not easy.  There HAS been some success with stem cells of various types.  An experimentor in Asia caused some stem cells to grow into new capillary tissue in a patient, replacing something which medicine is otherwise completely incapable of fixing right now (those capillaries are just too small).  Some isolated tisue has also been grown from stem cells such as cartilage and heart tissue, demonstrating the possibility of growing just one organ for a graft.\n\nMajor diseases are still in the works, however... in large part because we still have a lot to learn!  One study just recently started injecting stem cells into the brains of terminally ill children - not intending to cure them, but just intending to learn how many they have to use, how and where they will implant, and what risks they pose to the patients.  As you can see, we're still kind of at the beginning of this whole thing, even though there has been some very promising work.\n\nAs to why the government has to pay for it... it actually is the case that the government pays for MOST scientific research that goes on.  Who else is going to pay in a capitalistic society?  Companies only want to fund things that are going to pay off directly for them; in this field they ARE competing with other countries and applicable results are probably still a ways off for things that would be massively profitable.  Private citizens don't usually have the resources to fund research much themselves, though Howard Hughes' vast monetary legacy would be one notable exception.\n\nThe bottom line, really, is that if researchers can't find money to do their work here, they will go someplace where they can.  That is why Missouri was trying to pass a law explicitly allowing such research - biotech companies in that state found that they were completely incapable of attracting scientists to work for them at any price that they could afford.  Some countries DO have different research structures:  in Japan the government can get all affected companies to pool resources and share the resulting technology, for example.  And perhaps for humanity as a whole it hardly matters whether Sweden, South Africa, or America makes all these discoveries... but it CERTAINLY matters for the economies of those specific countries!

The best source of stem cells is abortion.  That is starting to change, though--they are finding other good sources.

I doubt there are many stem cell researchers reading your question. You would need to checkout recent articles and news stories on the subject.

Everything you need to know about stems cells can be found on this page:\n\nhttp://stemcells.nih.gov/info/basics/basics4.asp\n\nCloning is creating a viable embryo that is an exact genetic copy of another animal (or plant?).  In animals, cloning is usually done by harvesting unfertilized eggs from a female, extracting the DNA from an egg, and inserting the extracted DNA into another egg to substitute for fertilization.  Cells other than eggs may also be used, but eggs are easiest to work with.

Stem cell enhancers is a natural botanical extract that helps your body maintain healthy stem cell physiology.  \n\nAdult stem cells are most abundantly found in bone marrow.  Stem cells circulate and function to replace dysfunctional cells, thus fulfilling the natural process of maintaining optimal health. stem cells derived from the bone marrow, travel throughout the body, and act to support optimal organ and tissue function.  Stem cell enhancers are products that support the natural role of adult stem cells.

Stem cells are primal cells that retain the ability to renew themselves through cell division and can differentiate into a wide range of specialized cell types\n\nBone marrow (or medulla ossea) is the soft tissue found in the hollow interior of bones. It is the place where most new blood cells are produced.

Adult stem cells are cells that can differentiate into different types of cells that in the same family, but cant differentiate into different types of cells that in different family. For example, bone marrow cells can become red blood cells, white blood cells,.....(generally blood cells). Bone marrow cells cant become brain cells or heart cells.\nAdult stem cells is used for transplant. For example, a person has hemophilia, he or she can be cured by transplanting healthy bone marrow cells.

Where do you live?\nThe US are currently being held back a bit in terms of research by the Government's conservative posture, meaning that no federal money is being put into controversial technologies such as stem cell research. A lot of researchers are going to Europe instead, seemingly opportunities there are growing.\nThere's probably still a lot of money in biology in the US, though. But it's decreasing.
