Stem cells

Stem cells are undifferentiated cells they can change into cells that are specialized. They can split up to create more of themselves. They are found in humans and animals. They are special because they are regenerative and malleable. They can also replicate themselves and repair and replace other tissues in the human body. There are two different types of stem cells in mammals there are embryonic stem cells and adult stem cells. Embryonic stem cells are grown from cells that are found in the embryo when it is just a couple of days old. An early embryo is called a blastocyst. Adult stem cells are found in the whole body they are found in the tissues from the bone marrow, brains, blood, skeletal muscle, and fat that’s in the body.
They can divide and self renew by making them to generate more of cell types from the organ or even generate again the whole original organ.
Embryonic stem cells could be used to make more and new tissues that have been gone or damaged due to diseases or injury. Tissues that are constantly replaced such as like blood and skin. Stem cells will most likely be replaced directly by the stem cells. This shows that stem cells can also cure diseases, researches have recently figured out that stem cells can cure Alzheimer, Alzheimer is a chronic disease that usually gets worse over time, the most common symptom is short term memory advanced symptoms are mood swings, disorientation and trouble speaking. Researchers have recently discover that by transplanting neural stem cells ‘which is a type of stem cell found in the brain’ into the brain in hope that they will make new healthy neurons although the researchers have only tested it on mice. Researchers have also discovered that stem cells can cure ALS, which is a disease that affects nerve cells in the brain and the spinal cord. It affects the ability of the brain to control muscle movement, so when you have ALS you lose the control of your muscle movement. Patients that have the disease for a long time may become paralyzed. Researchers have discovered that by transplanting stem cells or growth factors in the spinal cord would cure ALS or slow down the process. The process of the stem cell transplantations is still in the early stages, but seem to be safe. Although it is not certain that transplanted stem cells are resistant to the damage that causes the motor neurons to die and stem cells may need to be changed to be resistant to that damage. There could also be a chance that the stem cells used in transplant medicine can get rejected by the immune system from your body. Researchers have also discover that stem cells can help to cure other diseases such as blindness, blood disorders, blood supply, cartilage damage, diabetes, hearing loss, heart disease and damage, infertility, lung damage, Memory loss because of a brain tumor treatment, multiple sclerosis, muscular dystrophy, organ replacement, Parkinson’s disease, platelet transfusion, spinal cord injury, tissue damage, and cancer. Stem cells are very important during the process of chemotherapy because the chemotherapy kills the cancer but it also kills the stem cells in the bone marrow, you need the stem cells in your body since stem cells are early blood cells in the bone marrow that develop into red blood cells, white blood cells and platelets. After chemotherapy the high dose treatment you can transplant stem cells to replace those that the cancer treatment has killed. We need those stem cells in order to survive because we need red blood cells to carry oxygen around our body. Stem cell transplant allows you that you can have a higher doses of chemotherapy. So there may be a bigger chance of surviving from cancer than using standard chemotherapy.
Researchers have done a lot of research on stem cells so far although they have only tested most of their experiments on mice, and aren’t sure that people will react the same way to their methods so it is not sure, that stem cells will actually cure all the diseases as it says the amount of diseases it will, although I hope that the researchers can continue their researcher to gain more knowledge and trust in there methods, so it can help cure many diseases. I personally think stem cells are amazing that they can replicate themselves, repair and replace other tissues in the body and cure diseases and help cure diseases such as cancer, which is a disease where they haven’t found medicine for yet, although a medicine and cure is highly needed. I hope they will be able to cure more cancer patients now that they have discovered, how to use stem cells in the process to kill the cancer. There should be much more money for the research about stem cells, I think that stem cells can cure much more than we already know now. Some people are against the research of stem cells due to religious reasons the think it’s the same as abortion since the need the stem cells from the embryo they say it has the same moral issues like abortion, but the researchers say that there is no substitute right now for research using embryos. they say the research has resulted in the destruction of only a hundred embryos which isn’t a lot , making it totally different from abortion, which results in the destruction of millions of human embryos every year.
