Stem cell research is a relatively new scientific field that focuses on the study and use of stem cells, which are a type of cell that can develop into different types of cells and tissues in the body. The purpose of this type of research is to better understand how these cells work and to develop methods to use them in medical treatments. This research has already shown great promise in helping to treat and cure many diseases, such as cancer, Parkinson's disease, Alzheimer's disease, and many others.
