Space & Hematology: New Insights
- MILAN—The European Hematology Association (EHA) Congress featured a session on space hematology, exploring the intersection of space research and medicine.
- Joseph Borg, PhD, from the University of Malta and NASA GeneLab, noted the increasing accessibility of space research.
- Borg said increased hbf can reduce symptoms and improve quality of life in disorders like sickle cell disease or beta-thalassemia.
Space hematology is offering groundbreaking insights into blood disorders. Recent research presented at the European Hematology Association (EHA) Congress highlights how the unique habitat of space, including microgravity and radiation, impacts the human body. Scientists are observing elevated fetal hemoglobin levels in astronauts, perhaps offering new avenues for treating conditions like sickle cell disease. Furthermore, studies reveal how spaceflight affects coagulation and immune function, providing a deeper understanding of both. These findings may help refine risk stratification for patients struggling with similar conditions on Earth.

Space Hematology Research Offers New insights into Blood Disorders
Updated June 16, 2025
MILAN—The European Hematology Association (EHA) Congress featured a session on space hematology, exploring the intersection of space research and medicine. Microgravity, radiation exposure, and isolation create extreme conditions that challenge human physiology, offering insights into hemoglobinopathies, coagulation disorders, and white blood cell dysfunction.
Joseph Borg, PhD, from the University of Malta and NASA GeneLab, noted the increasing accessibility of space research. His team’s findings show adult astronauts exhibit elevated levels of fetal hemoglobin (HbF), typically absent after infancy. The team analyzed blood samples pre-flight,during missions,and post-return,reporting overexpression of gamma-globin genes,suggesting reactivation of fetal erythropoiesis during spaceflight.
Borg said increased hbf can reduce symptoms and improve quality of life in disorders like sickle cell disease or beta-thalassemia. Inducing HbF through environmental triggers akin to those in space might offer a simpler alternative to gene-editing approaches.
Roopen Arya,MD,of King’s College Hospital,UK,noted that thrombosis risk in space has transitioned from theoretical concern to real issue. Guidelines for managing venous thromboembolism (VTE), developed by NASA’s VTE working group, are now available. Studies also show transient changes in coagulation and inflammatory markers in civilians participating in short-duration missions.
Judith-Irina Buchheim, MD, of Ludwig-Maximilians-Universität (LMU) München, Germany, presented evidence that spaceflight can reduce NK cell cytotoxicity, affect T-cell activation, and trigger a state resembling inflammaging. Buchheim said space is a good choice for aging research,as effects can be seen quickly.
Speakers at the EHA Congress emphasized that astronauts offer ideal study subjects,and space acts as a physiological accelerator,revealing stress-response patterns and disease models that could take years to emerge on Earth. Insights into HbF reactivation could inspire pharmacologic mimicry, and coagulation changes may refine risk stratification for hospitalized or immobilized patients. Immune dysregulation observed in space could help clarify mechanisms of aging, vaccine response, and infection susceptibility.
Martin Dreyling, MD, of LMU Hospital Munich, said space hematology may become part of clinical routine in 10-15 years. He added that young investigators are drawn to the field, attracted by its novelty, data richness, and interdisciplinary collaborations.
borg emphasized the need for ethical oversight, noting that astronauts provide informed consent for biological sampling, and some opt to receive personal results. He also emphasized the need for attention to these issues for people who will be able to access commercial spaceflight and who are not as trained and risk-aware as traditional astronauts.
What’s next
As more samples and subjects are sent into space and as repositories grow, the potential for clinical translation increases. The long-term vision is a broader pool of space travelers undergoing real-time health monitoring to yield diverse datasets.
