Joint injuries are difficult to treat because cartilage does not have the ability to heal itself. Researchers worldwide have been searching for a way to manipulate stem cell growth in order to repair cartilage and joints. However, the research is still in its early stages because researchers have difficulty getting the stem cells to remain and survive at the desired tissue location. Therefore, labs have now begun to use new nanomaterials, which mimic the chemical and physical characteristics of human tissue, in order to create scaffolds that will support and control the formation of cartilage.
