embryonic stem cells

Embryonic stem cells are special cells derived from early-stage embryos, typically just a few days old. They have the unique ability to develop into any type of cell in the body, which is why they are studied for their potential in medicine. Because they can transform into various cells, such as heart or nerve cells, researchers hope to use them to treat diseases like Parkinson's or spinal cord injuries. However, using embryonic stem cells raises ethical considerations regarding the source of the embryos, making it a complex topic in both science and ethics.
