A recent paper from a research team in Australia discusses the benefits and safety of stem cell therapy for knee repair.
Here are their opinions and findings:
- “Regenerative cellular therapies (stem cells), rather than being unique and experimental, are well established and practiced in the area of blood transfusion, bone marrow and tissue transplantation…They were initially recognized in bone marrow and display plasticity and multipotency (the ability to change/morph into other cell types, multiply, and signal other cells to being repairing damaged joints).
- Mesenchymal stem cell MSCs (connective tissue stem cells) suppress inflammatory T–cell proliferation and provide and anti-inflammatory effect.
- Mesenchymal stem cells express various growth factors – an array of bioactive molecules that stimulate local tissue repair – These growth factors, and the direct cell to cell contact between MSCs and chondrocytes (the present remaining cartilage cells in the joint), have been observed to influence chondrogenic differentiation and cartilage matrix formation – in simple terms – stem cells regenerated cartilage.
- “Intra-articular injections of MSCs have resulted in pain and functional improvement in a number of preclinical and clinical trials. Importantly, recent limited case series evidence has shown regrowth of cartilage volume and disease modification following MSC injections. Whilst recognizing the low level of scientific evidence (Level IV), a significant increase in cartilage volume in an accepted degenerative and progressive condition represents an exciting development.”
- The investigation of MSCs in the treatment of various conditions including osteoarthritis continues to grow. The National Institutes of Health lists 404 current trials in the area of MSCs. “1
The abundance of research is making it clear stem cells for knee osteoarthritis provides a promising treatment strategy for osteoarthritis. Supporting the research above is another new paper explaining how stem cells work on knee repair. The answer? Bone marrow stem cells increases cell proliferation of chondrocytes and inhibits inflammatory activity in osteoarthritis. In common language – it regrew cartilage and stop damaging chronic inflammation. 2 The same results expressed above.
These healing effects of stem cells are supported in many more studies. In one study, doctors followed patients for five years after stem cell injections for knee osteoarthritis. They found at FIVE YEAR follow up stem cell treated knees were still better than before treatment.3
More interesting is a second study from doctors in China who announced that in their animal studies, stem cells injected into the site of a bone fracture, promoted rapid and accelerated bone healing. 4
Here is what new research concluded: “Regenerative medicine (PRP and stem cells) may ultimately have profound implications in the way knee osteoarthritis is managed”5
The implications of the above research has helped revolutionize the way standardized medicine addresses problems of bone degeneration and necrosis (bone death).
So much so that researchers are looking at the osteoblasts, specialized mesenchyme-derived (stem) cells accountable for bone synthesis, remodelling and healing. What they are finding is that these cells rebuild bones through various mechanisms including cell homing or cell signalling. This is where stem cells communicate with the surrounding tissue to help them navigate to the site of the wound and differentiate themselves into the material to build bone.6 Other research suggests positive results even in cases of Avascular necrosis.7
Stem cells can also modulate the immune response of individuals and positively influence the microenvironment of the stem cells already present in the diseased tissue.8 The stem cells changed the environment.
The research above shows, cartilage can be regrown, bone can be regrown, chronic inflammation (swelling) shut off, healing turned on – this is why doctors are saying - stem cells can provide a curative effect.
