Understanding stem cell immortality

Stem cell research continues to strive to create safe and reliable ways to generate cells for medical applications. A new study identifies the role of the protein Nanog in stem cell development.

By acting much like a conductor of an orchestra, Nanog must be present during the final reprogramming phase of adult stem cells in order for other genes and proteins to come together to create a constant state of development, also known as pluripotency.

Researchers aim to transform embryonic and adult stem cells into pluripotent cells. These cells might then be turned into any type of body cell, offering possible treatment for diseases such as Alzheimer's or diabetes.
