Regenerative cell allografts, that occur naturally in the body, are “naive” or unspecialized. This means that, based on cues from their environment, these cells can transform into and assume the functions of a variety of different cells in the body. The ability to mature in a context-specific way is the key to the vast potential of cells in regenerative medicine. When injected into a damaged tissue, the cells specialize to carry out the necessary function in that particular area, improving symptoms and function.
