This type of research has been controversial since its inception. However, the scientific community has continued its work in this field, as research into stem cell treatments for Parkinson’s disease, Alzheimer’s disease and spinal cord injuries has yielded results too hopeful to ignore. It is expected to be a growing scientific field for the foreseeable future, and it is expected to evolve in the coming decades. This means there will be an ongoing need for researchers and, assuming this technology becomes commonplace, the need should continue to grow.
