Stem cells and regenerative medicine<br /> They are non-specialized cells but can differentiate into specialized cells, with their distinction with her ability to split, she constantly renews herself. Stem cell discovery is a relatively recent and reliable medical finding it has to be an important resource in treating many chronic diseases and serious injuries, such as kidney disease, liver and pancreas, and organ injuries nervous and skeletal system Stem cells are the body's raw materials - they are the cells that generate including all other cells with specialized functions. Under the circumstances In the body or in the laboratory, the stem cells divide to form more of the cells are called infant cells. These newborn cells either become new (self-renewing) stem cells specialized cells (via differentiation) have an additional specialized function, such as cells blood, brain cells, heart muscle cells or bone cells. No there are other cells in the body that have this natural ability to generate species new cells. Researchers and doctors hope that stem cell studies will help:<br /> Increased understanding of how the disease occurred. By observing stem cell growth to become cells in the bones, heart muscle, nerves, organs, and other tissues, can researchers and doctors can better understand how to get sick. Generating healthy cells to replace diseased cells (regenerative medicine).<br />Stem cells can be directed to specific cells, which can be used to regenerate and repair diseased or damaged tissues.<br />Categories of patients who could benefit from stem cell treatments include; People with spinal cord injuries, type 1 diabetes, and disease Parkinson's, amyotrophic lateral sclerosis, Alzheimer's disease, heart disease, stroke Brain, burns, cancer and osteoarthritis.<br />Stem cells have the potential to grow and become a new tissue for use in Agriculture operations and regenerative medicine. Researchers continue to provide information Advanced stem cells and their uses in regenerative medicine. Testing new drugs to see their safety and efficacy. Before using medications research on individuals, researchers can use some types of cells Stem test for drug safety and quality. It is likely to be of this type the test has a direct impact on the design of the drug intended for cardiac toxicity testing firstly. New areas of study include the effectiveness of using human stem cells, which has been programmed to become specific tissue cells for testing new drugs.<br />For the new drug test to be accurate, cells must be programmed to obtain Qualitative properties of the cells targeted by the drug. Researchers are still studying methods of programming cells to become specific cells. For example, neurons can be generated to test the new drug for the treatment of neurological diseases. Tests may show whether the drug is new Achieves an effect on cells and whether cells are damaged. Researchers have discovered that there are several sources of stem cells:<br /> Embryonic stem cells. These stem cells come from embryos it ranges from three to five days. At this point, the fetus is called a cyst show him "and he has about 150 cells. These stem cells are multi-capacity, that is, they can divide into more Stem cells or can become any type of cell in the body. This allows the possibility of using embryonic stem cells to reconfigure tissues and diseased or repaired organs. Stem cells in adults. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. And compared to the cells embryonic stem, as adult stem cells have a limited ability in formation of several cells in the body. Until recently, researchers believed that adult stem cells did not it can only create similar types of cells. For example, I guess researchers say that stem cells in the bone marrow make up only cells the blood. But evidence has emerged that adult stem cells can create types many cells. For example, stem cells may be able to marrow The bone create bone cells or the heart muscle.<br />This research led to clinical trials at an early stage to test its benefits and safety On humans. For example, adult stem cells undergo tests currently, people with neurological or cardiac disease. Adult cells turned into embryonic stem cell properties (High-power induced stem cells). Scientists have successfully transformed cells regularity in adults into stem cells using genetic reprogramming. By changing genes in adults, researchers can reprogram cells even they are similar in function to fetal stem cells. This new method may allow researchers to use reprogrammed cells Instead of embryonic stem cells, avoiding the immune system rejecting the cells new stem. However, scientists do not yet know whether to use it modified cells will cause harmful effects in humans or not. Researchers became able to take normal, connective tissue cells and reposition programmed to become functional heart cells. And in studies, the infected animals with a heart failure and injected with new heart cells, she showed improvement in heart function and survive. Stem cells before birth. Researchers have discovered stem cells in amniotic fluid as well as umbilical cord blood. These stem cells possess also the ability to change into specialized cells. Amniotic fluid fills and protects the sac surrounding the fetus that grows in the womb. The researchers were able to determine the presence of stem cells in samples of drawn amniotic fluid of pregnant women to test for the presence of malformations - a procedure called amniocentesis. More study is still needed on stem cells from amniotic fluid to understand its capabilities. Stem Cell Therapy (Regenerative Medicine): Stem Cell Therapy, also known as regenerative medicine, promotes A response to repair diseased, dysfunctional, or infected tissue with Stem cells or their derivatives. This is the ideal solution for organ transplantation and the use of cells instead of donor members, which are limited in terms of submit it. Researchers are working on stem cell growth in laboratories. These are employed Stem cells to be used specifically for certain types of cells, such as cells heart muscle, blood cells, or nerve cells. Custom cells can then be transplanted into someone. For example, if a person has heart disease, cells can be injected into the heart muscle. Has been the healthy implanted heart muscle cells then contribute to the repair of the heart muscle defective. Researchers have already shown that adult bone marrow cells are directed because heart-like cells can repair tissues. Doctors have performed implants Stem cells, also known as bone marrow transplants. in a Stem cell transplants, the stem cells replace the damaged cells because of a chemotherapy or disease or acting as a method for the donor's immune system to fight certain types of cancer and some blood-related diseases, such as cancer blood, lymph, neoplastic tumor, and multiple myeloma. These implants use adult stem cells or cord blood. Researchers are testing adult stem cells to treat conditions others, among them are a number of degenerative diseases such as heart failure.
