Research is beginning to dispel some of the mysteries surrounding the human body, particularly how the body regenerates tissue. In the early 1990s, scientists discovered small sections of RNA called microRNA or miRNA. This discovery allowed them to see more precisely how DNA functions in our bodies and the role these tiny molecules play in the process of regeneration of tissue.
The complex structure of ligaments and tendons that support our joints provides stability. They are composed of collagen, the most abundant protein in the body. Their tough, collagenous structure give the joint strength. This structure, however, also causes these tissues to have poor blood supply, making the joint prone to chronic conditions.
Every time you move, your muscles contract and relax. This process only takes a few seconds, but it is actually a quite complex process. Every activity in our body is controlled by muscles: breathing, circulation of blood, digestion. Even a simple smile is a result of muscle action. Muscles also help keep our body warm, maintain posture, and stabilize bones and joints. The body contains several types of muscles, some that work involuntarily, such as heart and organ muscles, and skeletal muscles that work primarily through voluntary action that is controlled consciously.
As we age, chronic injuries, along with normal wear and tear on our joints, often lead to arthritis. The smooth articular cartilage between the joints that cushions and protects begins to wear down, causing bones to rub against each other. Bone spurs often develop. The resulting friction leads to pain and swelling. This chronic inflammation results in arthritis and further degeneration of tissue.
Stem Cell Therapy is a hot topic in the news. With all the varying perspectives, information, and misinformation, combined with an influx of stem cell clinics, sorting out this large volume of information is difficult even for medical professionals.
