Stem-cell research in ISU offers promising treatment for blood diseases.

Researchers at Iowa State University have made a groundbreaking discovery that could eliminate the need for bone marrow transplants. The team, led by Raquel Espin Palazon, an assistant professor of genetics, development, and cell biology, found that a microbial sensor called Nod1 plays a vital role in the creation of blood stem cells. By understanding this process, researchers may be able to produce functional blood stem cells in vitro, which is currently not possible. This could lead to the development of patient-specific blood stem cells, eliminating the need to find donors and reducing the risks associated with graft-versus-host disease.

For patients with blood diseases and disorders, bone marrow or umbilical cord blood transplants are often the only treatment option. However, finding matching donors can be challenging, and even successful transplants can result in graft-versus-host disease. The ability to create blood stem cells that would not be attacked by the recipient’s immune system significantly lowers these risks. Espin Palazon believes that within her lifetime, and possibly within the next 20 years, new blood stem cells created from patients could become a reality. This discovery has the potential to revolutionize the field and benefit countless individuals in need of life-saving treatments.
