Stem Cell Strategy for Spinal Cord Injuries: The New Frontier
Knee Stem Cell Injections - Spinal cord injuries are injuries that occur to any level of the vertebrae. Although the hard bones from the spinal column protect the soft tissues of the spinal cord, vertebrae can still be broken or dislocated in a number of ways and cause traumatic injury to the spinal cord. Spinal cord injuries vary inside their severity, but almost inevitably cause various forms of compromised functionality since the spinal cord is in effect the primary pathway for information traveling around the human body. Just what body functions are impaired through the injury will depend on the region of the spine that has been damaged and the extent that the spine continues to be affected. Although serious impacts such as falls and car accidents account for many vertebrae injuries, tumors growing close to the column can also damage sensitive nerve tissue and possess the same effects.
Knee Stem Cell Injections - For many years scientists have been working to try and find a way to remedy the various ailments that vertebrae injuries can bring, though limited success. However, in recent years a pioneering new technology has emerged that is helping many people around the world regain part, if not completely, of their previously lost mobility. That treatment is the use of stem cells.
What are Stem Cells and Stem Cell Treatments?
Knee Stem Cell Treatment - Stem cells are found in all multi cellular organisms and are characterized by their ability to differentiate into a diverse range of specialized cells once they divide and renew themselves. They may be remarkable for their ability to regenerate themselves into any human cell. Their use in the treatment of various diseases and conditions, from Leukemia to Ms, is now becoming more common. Based on the condition, stem cells can be transplanted into the patient to assist renew and regenerate previously damaged cells, giving patients renewed hope when, before, no reliable treatment existed.
This principle is now being applied to treating spinal cord injuries using stem cells, as well as in instances where the patient has not experienced a complete spinal cord injury, i.e. an entire severing of the spinal-cord leading to a loss of function below the 'neurological' level. There has been positive results in helping patients recover greater sensory and physiological ability.
Spinal-cord Injury: How Stem Cell Treatment Works
When there is trauma to the spinal cord, myelopathy (damage to the fibres that carry messages both to and from the brain) has occurred. These 'myelinated fibre tracts' will be the focus of stem cell treatment, and therefore are the nerve cells the treatment helps to regenerate. The process usually follows three phases and usually requires no longer than a period of around five weeks in medical treatment for monitoring:
Phase one necessitates the harvesting of stem cells. The cells are extracted from a fetus's umbilical cord. They are then put through an activity whereby they are isolated and purified prior to being finally cultured being suitable for clinical use.
Phase two is the transplantation of the stem cells. This is achieved in one of three ways:
1) Lumbar puncture - a process used where stem cells could be injected directly into the spine.
2) Intravenous injection- stem cells are injected to the patient's vein.
3) Tissue injection - direct injection into target tissues.
Phase three requires the monitoring of the patient to make certain there are no adverse negative effects. The only side effects reported up to now were caused by the lumbar puncture, and not the stem cell treatment itself, with only 15% of patients reporting mild headaches. At that time under medical supervision, patients undergo various physiotherapy activities and other treatments as necessary.
Stem Cell Research and Treatment in China
China is fast becoming a world leader in stem cell research, and is also now a major centre for your stem cell treatment of many diseases and conditions. The Chinese government has poured many millions of dollars into research on regenerative medicine, which investment has really borne fruit in the last few years. As a result of this expanded investment, Chinese contributions to scientific journals on regenerative medicine topics leapt from 37 in 2000 to 1,116 in 2008, exceeded only from the contributions of experts in the united states, Germany, Japan and also the UK.
The government has additionally aggressively recruited high-caliber scientists trained abroad looking for its ambition to become a world leader within the field. Indeed, the McLaughlin-Rotman Centre for Global Health commented that, "the government's policy of attracting highly educated Chinese nationals returning to China has contributed significantly towards the country's success within the field." The authors were "amazed that almost all the top Chinese researchers inside the regenerative medicine field ended up educated in the US and the UK and gained extensive experiences there in leading edge research."
Although previously treatment in China may have been considered risky as a result of lax health and safety laws, recent years have seen an increase in legislation protecting the patient, and improving the functionality of clinics. Since 2009, proof of safety and efficacy through many studies is required by China's Ministry of Health for all stem cell and gene therapies, making certain Chinese clinics meet international standards inside their qualifications and methodology. By January 2010, about 1,500 patients had received laser hair removal for spinal cord injury at one Beijing clinic alone, including roughly 1,000 foreigners.
Furthermore, China has long held a place at the forefront of stem cell research to take care of all manner of conditions. A few of China's notable contributions to stem cell research are:
By transferring the nucleus of the human skin cell in to the immature ovum cell of the rabbit, researchers from your Shanghai hospital successfully produced embryonic human cells.
China thus far has created at least 25 human embryonic stem cell lines (some estimate over 70 stem cell lines), four of which are of a specialized type that during those times only two other groups worldwide had was able to create.
Harboured several human tissue types, created artificially, including blood vessel, tendon, bone, cartilage, skin, cornea and muscle fibre.
Furthermore, Chinese researchers are presently involved with a myriad of projects to aid aid patients through regenerative medicine and stem cell therapy. Here are several projects underway within Chinese institutions:
ChinaSCINet, a consortium of 27 medical facilities, are beginning phase 2 numerous studies to test the efficacy and safety of using cord blood stem cells and oral lithium to deal with about 40 patients with vertebrae injuries.
Clinical trials are underway around the use of stem cell therapies to take care of patients of cardiac arrest, artery obstruction, and liver and neural diseases.
Studies are underway on the potential use of stem cells to take care of heart, liver and blood diseases, eye cataracts, also to combat aging.
Testimonials from the Treatment of Spinal Cord Injuries in China
Many people of all ages and with varying levels of injury have received stem cell treatment in China during the last few years. It is important to understand that not every patient will react as well as others, and that the age of the patient and the severity of the damage greatly affect the likelihood of recovery. However, there have been many success stories from both Chinese citizens and foreigners.
Before her treatment began in January 2006, Ms. Pai, 38, from Shenyang couldn't move her body underneath the injury site, and it was unable to control her going number 2. Within 8 months with the treatment she regained movement in both her legs, could bend her knees (even though toes of one foot were still paralyzed) and was even capable of walk with crutches.
Razvan Iordache, a Romanian citizen aged 30, travelled to China for many bouts of stem cell treatment following any sort of accident while diving into a river that left him paralyzed from your neck down. Following his treatments, Razan reported in 2008 that doesn't only could he are now using his arms almost normally, and might feel pain in a number of of his fingers, he could "even feel warm and cold" sensations. He proceeded to add the following: "Now I'm able to control my urine for 10 minutes and the sensation for both urine and stool is way better. Generally, my system is more powerful than ever before."
Donald Maricelli, a 54 years old US citizen, a break down spinal cord injury following a fall in 2002. He underwent surgery to correct his lack of sensation in his lower body, however there were complications and Donald was left in a worse state than before. Before arriving for treatment in China, he had been unable to walk unaided. Pursuing the treatment, which commenced in November 2007, Donald makes significant improvements. He regained sensation throughout nearly all of his abdomen, and the sensation in his legs also improved. Particularly crucial, the sensation on the bottom of his feet went back, helping him simply to walk without tripping. Most significant to Donald was that he regained control and strength in his left leg, allowing him to walk significant distances and are a symbol of prolonged periods of time.
There are many more success stories from patients who have received this pioneering treatment to help correct varying degrees of spinal cord injury. However, it is usually important to remember that not all patients recover exactly the same functions in the same period of time. A lot of hard work switches into the post treatment rehabilitation, also it takes great drive, determination and ambition to allow the body to get back to more regular functionality. However, the work being done by scientists and clinics in China has shown time and again that stem cells hold a very important key to the future of helping people with spinal cord injuries recover their lost functions. Each month, more and more people are travelling to various cities across the country that offer different packages of treatment based on precisely what injury may be inflicted. The level of service has improved greatly recently, and continues to improve monthly, meaning that those unfortunate enough to get suffered spinal cord injuries need no more feel theirs is a lost cause. There exists a very real chance the standard of living of any patient can be improved with little pain, little hospital time, and a little motivation. The current evidence shows that stem cell therapy for spinal-cord injuries is the way forward.
