Mesenchymal Stem Cell Therapy for Hutchinson-Gilford Progeria: Improvements in Arterial Stiffness and Bone Mineral Density in a Single Case.
Article in Children (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectivesHutchinson-Gilford progeria syndrome (HGPS) is a rare genetic disorder that cause premature aging due to LMNA mutations and progerin accumulation. Although lonafarnib, an FDA-approved farnesyltransferase inhibitor, offers modest extension of life, the disease remains progressive. As progeria is associated with stem cell depletion and mesenchymal stem cell (MSC) therapy has shown efficacy in treating atherosclerosis, we aimed to evaluate its efficacy and safety in HGPS.
methodsA 7-year-old male with classic HGPS and preexisting severe cerebrovascular disease received four intravenous infusion of bone marrow-derived MSCs (2.5 × 10⁵ cells/kg) over 8 months. Growth, metabolic, cardiovascular, musculoskeletal, auditory, and inflammatory cytokines were monitored throughout the study. Prophylactic enoxaparin was administered to prevent vascular complications.
resultsMSC therapy was associated with improved lean body mass (11.5%), bone mineral density (L-spine z-score: 0.55 → 2.03), reduced arterial stiffness (9.98% reductionin pulse wave velocity), joint range of motion, dentition, and decreased sICAM-1 levels. However, Cardiovascular deterioration continued, and the patient passed away 10 months after the fourth dose, likely due to progression of the underlying vascular disease. No severe adverse effects were attributed to MSC therapy.
conclusionsMSC therapy may offer short-term benefits in arterial stiffness, bone health and inflammation in HGPS without notable safety concerns. Further studies are warranted to validate these findings, explore earlier intervention, and determine long-term efficacy and optimal dosing strategies.
