Stem cell research involves studying cells that have the unique ability to develop into many different cell types in the body. These cells can be found in embryos, as well as in adult tissues. Scientists are particularly interested in embryonic stem cells because they can become any cell type, which holds potential for treating various diseases and injuries. Researchers aim to understand how stem cells function and how they can be used in regenerative medicine. This field explores ways to repair or replace damaged tissues and organs, potentially offering new treatments for conditions like diabetes, heart disease, and spinal cord injuries.
