Stem cells represent a major turning point in the research and treatment of human medicine, has proved of great importance, and the ability to cure many incurable diseases and dangerous, in addition to its use in organ transplantation, In this context, doctors succeeded Ross in the treatment of diseases of childhood cancer, and diseases of the nervous system by stem cells for the first time in the history of medicine.
The Professor Giorgi Mintkevich Vice-President of the Center for treatment of cancers of the Russian Academy of Medical Sciences, that the resort to the use of stem cells is only in difficult cases that do not respond to conventional therapy and chemotherapy and radiation surgery, confirming that stem cells obtained from an infected person but by the same device The detachment of donor relatives.
Mintkevich He added that the use of stem cells led to significant progress in treating some cancers, indicating the success of treatment in about 60 per cent of the incidence of loss of red blood cells and fifty per cent of the central nervous system tumors.
The doctors were transferred stem cells from bone marrow in the dock of the patient to the spinal cord as indicated newspaper "Oman Today", pointing out that these cells travel through the spinal cord to the brain and reverse the cancerous tumors in the head or the rest of the body in patients He added that the technique has led to tangible results was the elimination of the central nervous system tumors, and the disappearance of the symptoms of the disease in many patients, as the treatment of these cells to be more effective in the onset of the cancerous tumor and reverse the spread of the scope into the patient.
Stem cells from dead cells
In this regard, British scientists found a new way to produce stem cells from dead embryos through in order to eliminate the diseases.
The Miodrag Stodgkovk professor embryology and stem cell biology at the University of Newcastle, that these embryos used in research have stopped growing and thus are among the dead.
The Stodgkovk it can use these dead embryos to produce embryonic stem cells, and thus give an additional source of stem cells for use in research because human embryos are very precious.
For his part, Dr. Robin Lovell-Badge, head of the development of embryology at the National Institute for Medical Research, that the importance of this research lies in the discovery that all embryos, including the dead can be used in stem cell research.
Stem cells re-sprouting roots of teeth
In the context of talking about some uses of stem cells to treat certain types of diseases, researchers have successfully generated tooth root and supporting tooth ligaments to assist in the repair process of the Taj Sun teeth, through the use of stem cells taken from wisdom teeth of objects in experiments on very small pigs .
The Ocharacanutor Sonjtao Chi in the Faculty of Dentistry University of Southern California, that the use of stem cell technology leads to the reconstruction of functional teeth in an animal model similar to humans.
The Shih said he hoped in the coming years to be in patients with sufficient bone implant in the jaw to support the implant, and those who do not have this therapy would be a great substitute.
A new way to grow blood vessels
Canadian researchers indicate the possibility of using stem cells taken from muscle tissue in the construction of new blood vessels for implantation in the human body.
The researchers of the study, presented at a meeting in the "Toronto", planted these stem cells into tubes, flexible, biodegradable biological agents in order to grow new blood vessels for rats, during the days of extracting the stem cells.
The researchers noted that these results lead to a new way to create customized blood vessels to grow in patients with heart and kidney.
The researchers wrote that these cells, so-called stem cells taken from the muscles are as adult stem cells differ from the versions derived from embryos, which is still currently under debate.
The researchers injected 10 million of these stem cells in the pipes diameter 2 ر 1
Mm, and grew stem cells in this box for a week before the tubes were sewn into the main artery in each rat's abdomen.
Re-vision of animals
Modern medical study has shown that human stem cells can partly restore vision in blinded rats, which is an indicator for the treatment of certain diseases in the eye.
The study showed that cells derived from human embryonic stem cells can rescue visual function in animals that otherwise would have gone blind, and these cells are master cells that formed a few days of pregnancy when the embryo is still a ball of cells.
New hope for patients with liver and sugar
Dr. Abdul Hamid Abaza, the Secretary-General of the Assembly of the institutes and teaching hospitals, that the Commission organized a seminar in which it discussed
A recent therapeutic discoveries that open the doors of hope for patients with liver failure and diabetes.
He added that this is done through the use of transmitters stem "of blood cells in the initial bone marrow," and by the initial cell transplantation for the patient himself in order to avoid the problem of the body rejecting the alien tissue.
Was the application of this stem cell therapy on patients in Egypt, cirrhosis, spinal injuries, showed promising results, which could lead to a new revolution in the treatment, where the success of cellular therapy from the patient the same achievement scientifically and economically.
By recovering from brain tumors
In the same area, U.S. researchers said it may be able to try to stem cell research in treating patients with strokes and brain tumors as of next year.
According to new research they have done that stem cells are attracted naturally to the diseased parts of the brain.
The study demonstrated for the first time that stem cells taken from bone marrow in adults can be transformed into different types of cells in the central nervous system.
The experiments were conducted so far on mice, researchers want to apply what they know to humans. Referred to as stem cells can turn into any type of specialized cell in the body.
Method for the treatment of leukemia
British researchers also developed a new method based on stem cells can help patients with advanced stages of cancer of the blood or lymphatic tumors.
And the intervention of scientists genetically donated stem cells, the master cells that can become any type of cells so that they can stay alive during chemotherapy higher toxicity.
He explained that one of the researchers can use stem cell transplantation in the treatment of leukemia and tumors Allmifawi device, which usually do not respond to conventional therapy, and to grow stem cells in the patient to make a response to the immunity against the disease, often followed by this strong chemotherapy kill cancer cells.
A cure for muscular dystrophy
A team of Italian researchers, a kind of stem cells found in the blood vessels can be S
Thaddamha in the renewal of the muscles. The scientists at the Institute stem cell research, carrying out tests on mice infected one in pictures muscular atrophy disease that causes the destruction of muscle. They found that stem cells of blood vessels of GM, called "Misanjjublasts", has the ability to renew and to generate new muscle tissue in the rat.
The stem cells are "master cells", which could be spurred to grow in different types of tissue.
The perception of the scientists to collect stem cells from blood vessels of the human patient, and then genetically modified in the laboratory, and then injected again into the bloodstream. Instead, scientists that this process will lead to the transfer cells to the muscles of the patient, and then START in the production of muscle cells intact and healthy. They said the body would not reject these cells, because the origin of the body of the patient himself.
