For decades, biologists have been using stem cells to figure out possible cures for different diseases and even prevent them. Stem cells are cells that can become useable in certain tissues in the body (according to an infant), or tissue cells that are already found in blood, bones, the brain, and skin (in adults or children). Stem cells are being used for patients with lymphoma (begins in the immune system), leukemia (cancer of white blood cells), and other types of blood disorders. Stem cells come from adult stem cells, and embryonic cells. Embryonic (blastocyst) stem cells come from embryos that are usually three to five days old. They contain 150 cells that are useable for stem cell research. These embryos are usually created as in vitro fertilization (a bunch of eggs that are fertilized but only one is put inside of a woman). Reproduction happens when a male’s sperm is fertilized in a woman’s egg to create a zygote (cell). Scientists can verify the cells are embryonic by them being able to be duplicated and the cells ability to become other cell types; this makes embryonic cells flexible. Adult stem cells are found in adult tissues in very small numbers. These cells are only used in certain areas where they are found such as bone marrow or adipose tissue (fat). The technologies used are peripheral blood stem cells and bone marrow stem cells. They can be obtained by drawing blood which makes them easier to gather than stem cells from bone marrow. This is usually challenging because these blood stem cells aren’t very populated in the bloodstream. Bone marrow stem cell technology has been used for more than twenty years. According to the National Cancer Institute: “They are most effective when the ... ... middle of paper ... .... It may take researchers to repeatedly try to receive the desired stem cell line. Adult stem cells are found in tissues that are already in their mature stage, and are limited on their flexibility. Adult stem cells cannot be storage for very long, and may have genetic defects. Stem cell research has been around for some time, and many people have been cured from certain diseases because of it. Many scientists observe that embryonic stem cells are easier and flexible to use than adult stem cells Adult cells are diseased curable cells as well to a certain extent because they are taken from certain tissues that are already established in an area of the body. Stem cell research has long ways to go for scientists to be able to use them to cure all cancers, infectious diseases, and other health problems however stem cells are on the path of changing the world.
Because stem cells are essentially a blank slate, scientists are theoretically capable of growing any human tissue cell. There is enormous medical potential in this. Stem cell research is the next step in advancing the medical field. It is comparable to the discovery of penicillin or the inoculation for smallpox.
Stem cells have several potential applications. Stem cells can be used to study development by helping us to understand how a complex organism develops from a fertilized egg. Some of the serious medical conditions such as cancer and birth defects which are lead by abnormal cell division and differentiation will have new therapy dealing with stem cell research. Stem cells have the ability to replace damaged cells and treat disease of extensive burns, leukemia (a cancer of blood forming tissues) and other blood disorders. Today, doctor use donated tissues and organs to replace damaged tissue, but the need for the tissues and organs far outweighs the available supply. With the stem cells, it can offer the enormous sources of replacement cells and tissues. Third, stem cells could be used to study disease. Today, scientists use stem cells to model disease processes in the laboratory to better understand what goes wrong in the disease genes. Finally, stem cells could provide a resource for testing new medical treatments. Lot of new medications could be tested on specialized cells from stem cell lines which can reduce the animal testing. For example, cancer cell lines are used to screen potential anti tumor drugs to see the effects on cells.
A more recent discovery, made in 2014, stem cells are being created from cells of young mice, this involves taking mature cells from mice and turning them into embryonic like stem cells, this new technique has not yet been tested in humans.
Stem cell research is when you take these cells and see how they can cure or treat diseases. Stem cell research has a few uses. One of the uses is to create cures and treatments. Another use is to grow new organs for people. Some organs are grown in a petri dish while others are grown in an animal.
Stem cell research is a topic almost everybody in the world has a viewpoint on. Many view the issue of stem cell research and stem cell therapy as morally wrong and a crime against humanity, others view the study of stem cells as the next step in modern science. What are stem cells? Stem cells are non-specialized cells that have the capability to mature into more specified cells to help with certain functions or diseases. Cells are the basic building blocks of the human body and these tiny structures compose the skin, muscles, bones, and all of our internal organs. Cells are necessary for our body to live, there are over one-hundred specialized cells in our body. Stem cell research should be supported due to the plethora of potential benefits to the medical community and the human race as a whole.
Stem cells are becoming a powerful new tool for replacing damaged or destroyed tissue in different parts of the body. There are two basic types, embryonic stem cells and adult stem cells. Stem cells, found in the body, can engender exact facsimiles of themselves. They have the capacity to construct a number of specially designed cells such as heart muscle cells, liver tissue cells, brain tissue cells, etc. Embryonic stem cells are extracted from aborted fetuses or embryos left over from in vitro fertilization. Adult stem cells are found in both children and adults. Adult stem cells can be utilized for a circumscribed number of other kinds of cells while embryonic stem cells are able to individualize into over two hundred types of cells. Embryonic stem cell research is so controversial because society is judging whether or not taking stem cells from days old embryos is immoral, or if doctors should look past the cons and do what is necessary to eventually preserve many lives.
Stem cells can grow a new liver for someone with liver disease, stem cells can grow a new spinal cord for someone with a spinal injury, stem cells can grow new nerve cells for someone with Alzheimer's disease, and stem cells can grow a new pancreas for my cousin, Rebecca. With a new, nondiabetic pancreas, Rebecca and other type 1 diabetes patients will no longer need to check her blood sugar, inject insulin, or live in fear of complications. Stem cells can also be used to conduct experiments that would be unethical to do on humans. For example, a scientist wanting to learn more about the effects of alcohol on the liver could grow livers in the lab, subject them to varying levels of alcohol, and record the results, all without needing to use a human. Stem cells, if the research for it is funded, will be a major scientific breakthrough on par with
You are able to use embryonic stem cells in the scientific community because the stem cells have the ability to produce replacement tissue such as muscle, bone and nervous tissue and would revolutionize medicine. Human stem cells are currently being used to test new drugs. All types of new medications are tested for safety on differentiated cells generated from human pluripotent cell lines. Other kinds of cell lines have a long history of being used in this way. For example, cancer cell lines are used to screen potential anti-tumor drugs. As for today, donated organs and tissues are often used to replace ailing or destroyed tissue. Stem cells, directed to differentiate into specific cell types, offer the possibility of a renewable source of replacement cells and tissues to treat diseases including macular degeneration, spinal cord injury, stroke, burns, heart disease, diabetes, osteoarthritis, and rheumatoid
The Canadian Stem Cell Foundation claims that, “Bone marrow stem cell transplantation has been curing some kinds of cancer for decades, but in other potential areas we’ve barely begun scratching the surface” Currently there are several clinical trials being done involving stem cells. One current clinical trial is working towards healing hearts, or using stem cells to grow new hearts that are made specifically for transplant patients. This research could be very helpful in the future. Every year 70,000 Canadians have heart attacks, and 23,000 of them could greatly benefit from this medical advancement. Scientists are currently working extremely hard to find an absolute solution to this problem. As of right now they think that the solution will be found in the next three years. Another new clinical trial wants to use stem cells to cure spinal cord injuries by injecting stem cells. As of right now this is more of an idea than a plan, but it could definitely be available in the future. Doctors have injected neural stem cells, in hopes of them developing paths to connect the nerve fibers, and stimulating regrowth. So far patients have only shown small improvements, but with more research there could be a great impact. Regardless, the future of stem cells, and what they're capable of is looking
Stem cells definitely have the ability to have a large impact in the science and medical fields. Science has grown so fast into finding new ways to treat a large number of different medical conditions and it is only a matter of time till these new findings are put into effect. The stem cells among us already have the ability to restore tissue and to also transform into different types of cells to fix diseases. The adult and embryonic cells are cells that scientists will continue to use to treat the many different diseases. Therefore, it is very important to know the basics of stem cells, the difference between the types of stem cells, and the possible uses of stem cells because science is moving quickly to have a promising future for those in need of medical help.
A stem cell is a cell that does not have a specific job, function or structure and are known as undifferentiated cells which have the potential of becoming many different cell types within the human body. Embryonic stem cells are taken from embryos and are known as pluripotent because they can become all cell types of the body. After development, adult stem cells are found to multiply by cell division to replace dying cells and restore damaged tissues. They are known to be limited to differentiating into different cell types of their own original tissue origin. Embryonic stem cells are taken from three main sources in a human including from cell lines that already exist, spare embryos left over from fertility treatment and from custom made embryos. Adult stem cells can be found in organs and tissues like brain tissue, bone marrow, blood vessels, gut, liver and more. Scientists are now trying to discover how some tissues and organs contain a small number of adult stem cells and how these stem cells help to maintain the tissues and organs.
Stem cells are extremely important necessities in multicellular organisms, such as animals and humans. They are used to repair damaged tissues by the process of cell division and they can also transform into different tissues and organs.1 Stem cells are important because they have the ability to aid with diseases, such as leukemia. They also generate specialized cells, meaning that without stem cells, important organs that power the human body would not exist.2
Currently they are doing more research on different ways to obtain stem cells, without harvesting an embryo. According to the National Institutes of Health, the first way to obtain different stem cells is through an adult’s surrounding organ tissues. Adult stem cells are found within a body’s organ tissues. Their main purpose is to repair and maintain those tissues, using cells to multiply in order to replace old tissue. Scientists have found that since these reparative cells have the ability to create new tissues, they could very well create the organs where they are located through the right conditions. This way of obtaining stem cells has been much less controversial than the original way of obtaining them, but at the same time, is a lot less efficient. Generating a new organ or body part is time consuming through this method, but we have to keep in mind that scientists are still finding other ways on how to obtain stem cells.
Normally there are very small amounts of stem cells in tissues, and once they are removed from the body, their size to divide are limited, which are making the generation of large amounts of stem cells difficult. In laboratories, many scientists are finding better ways to grow large quantities of adult stem cells in cell culture and to control or manipulate the stem cells to make specific cell types so they can be used to treat diseases, and injuries. Some potential treatments include repairing heart muscles, diabetes, cancer, aids, and more. Some test that is used to identify adult stem cells is by leveling the cells in a living tissue with molecular markers and then they define the specialized cell type that was produced. Another way is they remove cells from a living organism, like an animal and label it in the cell culture. Then they transplant them back into another live animal to see if the cells replace their tissue of the origin. This procedure must establish that a single adult stem cell can produce a line of genetically identical cells that then gives intensification to all the appropriate distinguished cell types of the
Stem cells are unspecialized tissues that have two most important features that make them different from other cells in the human body. First, they can increase their numbers for too long periods by means of cell division. Second, every time a stem mobile phone divides to hundreds of originate cell , each and every new originate can separate during early on life of them, and become specialized cells like red blood flow cell , muscle mass cell, human brain cell , or nerve mobile. In this century, scientists started out research concerning how to use originate cells to treat incurable illnesses. As well as they extracting embryonic stem adult and cells originate cells to increase the number in scientific labs.. Scientists found ways to derive embryonic originate cells from early mouse embryos almost 31 years ago, in 1981. The comprehensive study in the biology of mouse stem cells generated the discovery. At a later time , in 1998, of a strategy to derive stem cells from human embryos and expand the cells in the lab. ...
