Stem Cell Therapy is a non-invasive treatment to replace the damaged cells within the body. It is a form of regenerative medicine to replace the damaged Cells. Stem cell therapy is being researched as a possible treatment for Amyotrophic Lateral Sclerosis (ALS). Stem cells are able to acquire new specialized characteristics by being induced in a lab through differentiation and/or trans-differentiation. Stem cells are like mavericks of the medical world. They are able to transform in ways that other cell types can't, with the potential to generate different types of tissues and even help heal damaged tissue. Because they have this unique ability to regenerate, many researchers believe that stem cell-based therapies may one day be a viable remedy for diseases such as Alzheimer's and even paralysis. Stem cells are controversial because their study has a long way to go before, they can be expanded. However, embryonic stem cells are currently being explored by researchers around the globe; more studies must be conducted before such studies can be expanded.
