    Inflammatory Memory in Human Hematopoietic Stem Cells as a Driver of Clonal Selection in Aging and Cancer

    Hematopoietic stem cells make blood across the lifespan, but they do not all behave the same way. Stephanie Xie, Ph.D., Scientist at Princess Margaret Cancer Centre, University of Toronto, examines how these rare cells self-renew, differentiate, and respond to inflammatory stress, asking whether differences in the stem cell pool help explain why aging affects people so differently. Xie identifies two hematopoietic stem cell subsets, including one that retains inflammatory memory after stress recovery, and connects this state to aging, clonal hematopoiesis, sickle cell disease, post-COVID recovery, and mortality risk markers in blood. Her research also raises questions about whether targeting the inflammatory environment, including through GLP-1 receptor agonists or metformin, could help mitigate clonal hematopoiesis. Understanding these patterns could clarify how inflammation shapes blood production, cancer risk, and immune health over time.

    Gene Therapies and Rare Disease - Medicine Informing Novel Discoveries (MIND)

    Rare disease research is creating new paths for diagnosis, treatment, and broader medical discovery. Gene therapy can repair or replace faulty genes, and work on cystinosis has led to a stem cell platform now being applied to Danon disease, Sanfilippo syndrome C, Friedreich’s ataxia, and Alzheimer’s research. Funding programs support gene therapy, clinical trials, and new platform approaches for rare diseases. CAR-T cell research is also advancing treatment possibilities for pediatric brain tumors, including early results in children with DIPG and diffuse midline glioma. A patient advocate shares her daughter’s diagnostic odyssey and treatment for TUBB4A leukodystrophy. Together, these stories show why rare disease research matters beyond rarity.

    Stem-Cell Aging and Pathways to Precancer Evolution

    Pre-cancer and cancer can begin when stressed blood-forming stem cells lose their normal controls. Catriona Jamieson, M.D., Ph.D., UC San Diego, explains how inflammation-linked editing enzymes, repetitive elements in the genome, and stem cell stress shape the progression from myeloproliferative neoplasms to acute myeloid leukemia. Jamison examines how spaceflight accelerates stem cell aging, how some astronauts mobilize a resilient regenerative stem cell population, and how tumor organoids in space help reveal drug responses by activating the enzyme ADAR1. This work helps explain how cancer starts, why it can return, and how space-based research may speed the development of therapies that stop malignant stem cells before disease advances.

    From Electronic Health Records to Space Medicine: Building the Future of Space Healthcare

    Space healthcare depends on connected health data that can follow people wherever care happens. Peter DeVault, Epic, explains how electronic health record tools built for hospitals, labs, and patients can also support healthcare in space. DeVault describes patient-facing tools like MyChart, interoperability across health systems, structured genomics and pharmacogenomics in the patient record, and Cosmos, Epic’s patient data aggregation platform with about 300 million longitudinal records. He also examines AI capabilities that can generate possible future health scenarios and expand to telemetry and molecular data collected before, during, and after a mission. This work helps explain how records, data sharing, and predictive tools could support astronaut health and resilience and why those capabilities may be necessary for the future of space medicine.

    From Orbital Experiments to Curing Earthling Diseases: How Space-Enabled Biotechnology is Advancing Neuroscience on Earth

    Brain aging and disease research can gain new insights from space. Aline M.A. Martins, Ph.D., UC San Diego, explains how neuroscience studies in space use brain organoids, proteomics, and single-cell analysis to understand cognition decline, space-induced neurosenescence, and disease-related changes. Martins examines molecular markers of senescence, mitochondrial impairment, and neuroinflammation in organoid models, including Rett syndrome, while also comparing how space affects organoids of different ages. She shows that space can accelerate aging-related changes and affect cell types differently, helping clarify how space biology may speed drug discovery and reveal biomarkers for disease. This work helps explain how space research can inform treatments on Earth and points toward faster preclinical testing and broader understanding of brain disease.

    Microgravity at Scale: Turning Insight into Impact

    Microgravity can change biological systems in ways that may open new paths for biomedical research and commercialization in space. Twyman Clements, Space Tango, explains how “middleware” helps connect research use cases with space infrastructure by adapting terrestrial processes and supply chains for a spaceflight environment. Clements examines how long-duration microgravity creates different physical conditions, how Space Tango packages experiments into flight-ready lab systems, and how commercial space stations and reentry systems could help increase scale, throughput, and production value. He also points to more robotic systems that could support on-orbit sampling, imaging, and experiment assembly. This work helps explain how space-based biomedical research could move beyond small experimental missions and toward more practical, scalable platforms for discovery and development Series: "Stem Cell Channel" [Science] [Show ID: 41480]

    Leveraging Space

    Stem cell health in space matters for astronaut health and cancer research. Jessica Pham, UC San Diego, explains how spaceflight shapes normal hematopoietic stem cells and cancer stem cells through nano bioreactor studies, astronaut blood analysis, and tumor organoid work in low-Earth orbit. Pham examines increased cycling and reduced dormancy in space, reduced self-renewal after return, and ongoing research on cancer stem cells and their microenvironment, helping clarify how stem cells respond to spaceflight. This work helps explain how space conditions may change stem cell fitness over time and points toward a better understanding of astronaut health, long-duration missions, and cancer stem cell behavior.

    Growing Human Brains in Space

    Brain aging and neurological disease are hard to study because living human brain tissue is difficult to access. Alysson Muotri, Ph.D., UC San Diego, explains how brain organoids sent to space can model accelerated aging, reveal changes in neural networks, and help test potential treatments for brain disorders. Muotri examines space-induced senescence, fragmented network activity linked to dementia and Alzheimer’s patterns, and Rett syndrome findings showing inflammation tied to endogenous retroviruses and response to antiretroviral drugs in preclinical models. He also explores using brain organoids in space to screen neuroprotective compounds, including candidates identified from Amazon plants. This work helps explain how space biology can speed research on autism, Rett syndrome, Alzheimer’s disease, and other neurological conditions, and points toward new ways to test therapies on Earth.
