Human hematopoietic stem and progenitor cell (HSPC) fitness declines following exposure to stressors that reduce survival, dormancy, telomere maintenance, and self-renewal, thereby accelerating aging. While previous National Aeronautics and Space Administration (NASA) research revealed immune dysfunction in low-earth orbit (LEO), the impact of spaceflight on human HSPC aging had not been studied. To study HSPC aging, our NASA-supported Integrated Space Stem Cell Orbital Research (ISSCOR) team developed bone marrow niche nanobioreactors with lentiviral bicistronic fluorescent, ubiquitination-based cell-cycle indicator (FUCCI2BL) reporter for real-time HSPC tracking in artificial intelligence (AI)-driven CubeLabs.

Pathogen-specific CD4 T cells undergo dynamic expansion and contraction during infection, ultimately generating memory clones that shape the subsequent immune responses. However, the influence of distinct tissue environments on the differentiation and clonal selection of polyclonal T cells remains unclear, primarily because of the technical challenges in tracking these cells in vivo. To address this question, we generated Tracking Recently Activated Cell Kinetics (TRACK) mice, a dual-recombinase fate-mapping system that enables precise spatial and temporal labeling of recently activated CD4 T cells.

Clonal hematopoiesis (CH) is a frequently observed phenomenon in aging individuals without apparent illness and exhibits an increased prevalence in cancer patients. Mechanistic studies indicate that mutant immune cells alter the tumor microenvironment, leading to increased inflammation, blood vessel formation, and immune cell exhaustion. Paradoxically, these changes also preserve stem-like T-cell pools that can be utilized by immunotherapy.

Developmental plasticity at the behavioral repertoire level allows animals to incrementally adjust their behavioral phenotypes to match their environments through ontogeny. Quantifying this plasticity in sufficient resolution across substantial periods of development, however, has been challenging. Here, we use high-resolution tracking to monitor 45 genetically identical Amazon mollies ( reared in near-identical environments over their first four weeks of life.

While present on diverse plasmids, burden is often associated with the clonal spread of multi-drug resistant (MDR) epidemic lineages. In this study we sought to determine the relative contributions of clonal spread and plasmid transfer to burden across Michigan healthcare facilities over a decade.
