what are adult human stem cells and what are they use for?
466384
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.

STEM CELLS CAN BE PRESERVED THROUGH OUT THE LIFE AND CAN BE USEFUL FOR A PERSON IF SUFFERING FROM ANY DANGEROUS DISEASE, AS THEY MATCH WITH THE BODY CHEMISTRY.

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.

Mainly because embryonic stem cells proliferate (multiply rapidly) for a year or more in the laboratory without differentiating, but most adult stem cells cannot.  Scientists cannot have not determined why this is so but it works to their advantage.

A stem cell is essentially a cell with potential; it hasn’t yet become a specific, ‘useful’ cell. Stem cells are capable of becoming a variety of ‘useful’ cells. For example, a blood stem cell may become any type of blood cell, such as red or white. The basis of stem cell use in medicine is to manipulate their growth into tissues which people have lost through injury or disease, such as loss of certain brain cells in Parkinson’s disease, and thereby treat diseases previously considered incurable.\n\nTHERE ARE INFACT TWO TYPES OF STEM CELL undergoing medical research: Embryonic Stem Cells (ESCs) and Adult Stem Cells (ASCs). \n\nASCs are taken from a human adult, and usually either transplanted to another part of the body, or artificially encouraged to grow to greater numbers. ESCs are taken from human embryos which have been created artificially. Under the right conditions, these cells can then be grown in a lab, and if given the appropriate chemical signals, can be manipulated to become virtually any type of cell imaginable. In either case the aim is to replace tissues lost through disease.\n\nThose opposed to the use of ESCs strongly advocate the use of ASCs. However, many scientists believe that ASCs are ultimately less useful medically, as they cannot replace all types of cells. They exist in very small amounts and are therefore hard to find, and in extremely limited supply if wanted for transplantation on a large scale. They are also difficult to grow in culture. By contrast, ESCs are easy to isolate, grow and manipulate, and have a greater variety of uses. Thus, they are favoured by scientists as a medical tool. As ASCs come directly from the adult patient, there is essentially no controversy, as there are no life-issues at stake. It is the use of ESCs which\nis the cause of the debate, as it involves artificially creating a human embryo, harvesting the cells and then destroying the embryo. The moral objections to this revolve around a fundamental question - when does a group of cells constitute a human life? Put simply, are we playing God, and it is morally acceptable for us to do so? There has been no definitive conclusion, and the argument continues.\n\nThe variety of diseases which can potentially be treated with ESCs is huge, ranging from degenerative disorders such as Parkinson’s disease, to diabetes, and even cancer. If successful, it could be the greatest reliever of human suffering since the introduction of antibiotics. However,\nthe moral arguments surrounding their use do not look set to be resolved any time soon. Regardless, the immense potential medical benefits cannot be ignored, and so research continues amidst the controversy.

Stem cells are remarkable in that they can develop into all sorts of other specialised cells.\nOnce a cell is specialised it cannot change.\nStem cells therefore have the potential to replace cells that have been damaged by disease or injury.\n\nLook here:

Seperating cells from Morula to use them for medical purpose is technically feasible. But at present seperating such cells is not feasible. Some more research is needed.

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.

The stem cell is the only cell that can grow into any other cell in your body. Therefore, the cells are grown into a type of tissue and then used for some type of treatment.

I am sure you meant stem cells, not steam cells. Syeam would kill cells. It is used to sterilize. Stem cells are cells which are nondifferentiated yet. That means they are living but have not decided which type of body cell to be yet. Live cell therapies include blood transfusion, bone marrow exchange, and conception therapy.

My husband was diagnosed with Non-Hodgkin's Lymphoma and was given an autologus stem cell transplant that sent him into remission from cancer.\n\nStem cells are master cells in your body that can form into other needed cells in your body, like muscle cells, blood cells, or brain cells.  Or, they can form more stem cells.  You can think of them like a constant repair system for your body.  \n\nIn the case of my husband, the cancer had invaded his bone marrow - this proved to be very serious since the marrow is where blood is made.  His own stem cells were harvested from his blood stream and sterilized to prevent any cancer from being saved.  An extremely high dose of chemotherapy was given to kill basically everything in his marrow.  The stem cells were then reintroduced to his body - and they went to work!  Since it's the stem cell's job to figure out what's needed to make the body function properly, it made new marrow cells!  And then he had new marrow and no cancer!\n\nThis is sort of a simplistic view, but I hope it helps!

I dont think there's any evidence to claim that they are at this point. Umbilical cord stem cells do NOT have more capability then embryonic stem cells EVER. Embryonic stem cells are totipotent and umbilical cord cells, which are adult stem cells, are only pluripotent. While they cannot become any cell in the human body as ES cells can, they can become several specialized cells of the cell type they are. since the umbilical cord is used for blood and immunological cells and such, its stem cells can be used to produce more of any of those. This is why umbilical stem cells is commongly used in bone marrow transplants (bone marrow is where the cell components of your blood are created).\n\nThey are also of more use now than embryonic stem cells because we have not yet been able to produce a viable embryonic stem cell line from a cloned embryo. We can easily do it with an embryo which has been donated to research, but the problem there is that the genetic make-up of the embryonic stem cells will be foreign and the same fear of rejection and search for a close-enough match will occur. If stem cells are taken from one's own umbilical cord, it will be of their own genetic make up, thus their own cells.\n\n...This was a very long and possibly confusing answer. I hope it helps anyway. If you have any further questions you can contact me.

That bunch of cells could instrumental in saving millions of lives,stem cell research.\nWhat about my right to live?.The best medicine should be available to every body, but perhaps procedures/treatments that arise from stem cell research could be optional.\ni.e.'Miss smith you have cancer we can cure it, but the treatment comes from stem cell research.Would you like the treatment or would you prefer to die painfully?,and would you like frys with that?.

Pros - Stem cell research allows us to reproduce vital organs in the body and regenerate our own tissue.  It could help us treat and heal previously untouchable diseases like Diabetes, Parkinson's disease, Alzheimer's.  It could allow people who were blind to see again, stroke victims or paraplegics to walk again.  It could advance medicine as we know it like the creation of penicillin.\nCons - Bush will hate you

stem cell research itself isn't bad. What's bad (many agree) is where the stem cells are harvested. Stem cells are unique cells in that they have the capability to "become" almost any other type of human cell. They are used to help regenerate injured or diseased tissues in many areas of the body. Stem cells can be found in several areas, including bone marrow. Bone marrow stem cells have been used for many uses, such as helping subjects rebuild muscular proteins. The stem cells join with and become the cells they are partnered with.\n\nWhat makes many people upset is when stem cells, which are readily available from adult bone marrow (including the subject's own bone marrow), are, instead, harvested from aborted embryos. This practice has led to many arguments over sanctity of life, when life actually begins, etc. Many suggest that rather than enrage the controversy and destroy embryos, the stem cells should be taken from the vastly more available adult bone marrow in a process which is much less damaging to human life.

I think there are far too many people who have never actually examined stem cell research that make assumptions about unborn babies being involved. Embryonic stem cells are only a small part of the issue here. I myself have a hard time figuring out where the dividing line is on embryonic cells, since every time a human being has sex they kill more potential unborn babies, and every time a woman menstruates she is killing a potential baby. I can't figure that one out. Why draw the line at fertility? I know I don't have an answer. \n\nAnd where do you get millions of embryonic stem cells? That many don't exist. Since they are taken from in vitro fertilization with the permission of the donors, and would have been disposed of anyway as waste, how does this translate into killing innocent babies?\nhttp://stemcells.nih.gov/info/basics/basics3.asp\n\nBut, for adult stem cells there is absolutely no connection to this argument about abortion. I quote: \n\nA. Where are adult stem cells found and what do they normally do?\nAdult stem cells have been identified in many organs and tissues. One important point to understand about adult stem cells is that there are a very small number of stem cells in each tissue. Stem cells are thought to reside in a specific area of each tissue where they may remain quiescent (non-dividing) for many years until they are activated by disease or tissue injury. The adult tissues reported to contain stem cells include brain, bone marrow, peripheral blood, blood vessels, skeletal muscle, skin and liver."\n\nWhere in adult stem cell research is the ethical or religious problem? I just don't see it. I'm not so sure that religion has taken over science, but am worried that ignorance has taken over government.\n\nFinally, why is this under EARTH SCIENCE and not BIOLOGY?

They are like little baby cells that don't really know what they want to be yet (unless they are already adult stem cells) You can put them in with a bunch of cells of the same kind and they will grow into that type of cell.
