Stem Cell Strategy for Spinal Cord Injuries: The newest Frontier

Knee Stem Cell Treatment - Spinal cord injuries are injuries that happen to any level of the vertebrae. Although the hard bones with the spinal column protect the soft tissues with the spinal cord, vertebrae can still be broken or dislocated in many different ways and cause traumatic problems for 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 main 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 which has been damaged and the extent this agreement the spine has been affected. Although serious impacts including falls and car accidents account for many spinal cord injuries, tumors growing near to the column can also damage sensitive nerve tissue and possess the same effects.

Knee Stem Cells - For many years scientists have been trying to try and find a way to remedy the many ailments that vertebrae injuries can bring, but with limited success. However, in recent years a pioneering new technology has emerged that is helping lots of people around the world regain part, if not all, 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 located in all multi cellular organisms and so 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 capacity to regenerate themselves into any human cell. Their use within the treatment of various diseases and scenarios, from Leukemia to Ms, is now becoming more common. Depending on the condition, stem cells can be transplanted into the patient to help 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, and in instances where the patient has not yet experienced a complete spinal-cord injury, i.e. a complete severing of the vertebrae leading to a loss of function beneath the 'neurological' level. There has been good success in helping patients recover greater sensory and physiological ability.

Spinal-cord Injury: How Stem Cell Treatment Works

If you find 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 how the treatment helps to regenerate. The task usually follows three phases and usually requires no longer than a period of around five weeks in medical treatment for monitoring:

Phase one requires the harvesting of stem cells. Cellular structure are extracted from a fetus's umbilical cord. They are then put through an activity whereby they are isolated and purified before they are finally cultured to be suitable for clinical use.

Phase two will be the transplantation of the stem cells. This is done in one of three ways:

1) Lumbar puncture - an operation used where stem cells could be injected directly into the spine.

2) Intravenous injection- stem cells are injected in to the patient's vein.

3) Tissue injection - direct injection into target tissues.

Phase three involves the monitoring of the patient to make sure there are no adverse unwanted effects. The only side effects reported to date were caused by the lumbar puncture, and not the stem cell treatment itself, just 15% of patients reporting mild headaches. During the 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 now a major centre for that stem cell management of many diseases and conditions. The Chinese government has poured many millions of dollars into research on regenerative medicine, and that investment has really borne fruit within 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 through the contributions of experts in the united states, Germany, Japan and the UK.

The government has additionally aggressively recruited high-caliber scientists trained abroad in search of 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 to China has contributed significantly towards the country's success in the field." The authors were "amazed that the majority the top Chinese researchers within the regenerative medicine field had been educated in the US as well as the UK and gained extensive working experience there in innovative research."

Although before treatment in China could have been considered risky because of lax health and safety laws, the past few years have seen an increase in legislation protecting the individual, and improving the functionality of clinics. Since 2009, evidence of safety and efficacy through numerous studies is required by China's Ministry of Health for all stem cell and gene therapies, making sure Chinese clinics meet international standards inside their qualifications and methodology. At the time of 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.

In addition to this, China has long held a location at the forefront of stem cell research to take care of all manner of conditions. A number of China's notable contributions to stem cell research are:

By transferring the nucleus of your human skin cell in to the immature ovum cell of a rabbit, researchers from a Shanghai hospital successfully produced embryonic human cells.
China up to now 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 in those days only two other groups worldwide had managed to create.
Harboured several human tissue types, created artificially, including blood vessel, tendon, bone, cartilage, skin, cornea and muscle fibre.
Furthermore, Chinese researchers are involved with a myriad of projects to aid aid patients through regenerative medicine and stem cell therapy. Listed 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 utilizing cord blood stem cells and oral lithium to treat about 40 patients with spinal-cord injuries.
Clinical trials are underway about the use of stem cell therapies to treat patients of cardiac arrest, artery obstruction, and liver and neural diseases.
Research is underway on the potential usage of stem cells to deal with heart, liver and blood diseases, eye cataracts, and to combat aging.
Success Stories from the Treatment of Spinal Cord Injuries in China

Lots of people of all ages and with varying levels of injury have received stem cell treatment in China over the last few years. It is important to remember that not every patient will react as well as others, and that the age of the sufferer and the severity of the injury greatly affect the odds of recovery. However, there were 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 beneath the injury site, and it was unable to control her bowel movements. Within 8 months from the treatment she regained movement in the her legs, could bend her knees (although the toes of one foot remained as paralyzed) and was even able to walk with crutches.

Razvan Iordache, a Romanian citizen aged 30, travelled to China for many bouts of stem cell treatment following a major accident while diving in to a river that left him paralyzed in the neck down. Following his treatments, Razan reported in 2008 that not only could he are now using his arms almost normally, and might feel pain in several of his fingers, he could "even feel warm and cold" sensations. He continued to add the following: "Now I'm able to control my urine for Ten minutes and the sensation for both urine and stool is more preferable. Generally, my physique is more powerful than before."

Donald Maricelli, a 54 yr old US citizen, suffered a spinal cord injury carrying out a fall in 2002. He underwent a surgical procedure to correct his not enough sensation in his lower body, however there were complications and Donald remained in a worse state than ever before. Before arriving for treatment in China, he was still being unable to walk unaided. Following a treatment, which commenced in November 2007, Donald has created significant improvements. He regained sensation throughout the majority of his abdomen, and also the sensation in his legs also improved. Particularly significant, the sensation on the bottom of his feet returned, helping him to walk without tripping. Most important to Donald was that he regained control and strength as part of his left leg, allowing him to walk significant distances and stand for prolonged periods of time.

There are lots of more success stories from patients who've received this pioneering treatment to assist correct varying degrees of spinal cord injury. However, it is usually important to remember that not all patients recover the same functions in the same time frame. A lot of hard work adopts the post treatment rehabilitation, plus it takes great drive, determination and ambition make it possible for the body to get back to more regular functionality. However, the task being done by scientists and clinics in China shows time and again that stem cells hold an essential key to the future of helping people with spinal cord injuries recover their lost functions. On a monthly basis, more and more people are going to various cities across the country that offer different packages of treatment according to precisely what injury may be inflicted. The level of service has improved greatly lately, and continues to improve monthly, meaning that those unfortunate enough to have suffered spinal cord injuries need will no longer feel theirs is really a lost cause. There is a very real chance that the standard of living of any patient could 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.
