Endothelial Cell Senescence in Marfan Syndrome: Pathogenesis and Therapeutic Potential of TGF‐β Pathway Inhibition
Background Marfan syndrome (MFS) is a heritable connective tissue disorder caused by mutations in the Fibrillin‐1 gene, which encodes the extracellular matrix protein fibrillin‐1. Patients with MFS are predisposed to aortic aneurysms and dissections, significantly contributing to mortality. Emerging...

| description | Background Marfan syndrome (MFS) is a heritable connective tissue disorder caused by mutations in the Fibrillin‐1 gene, which encodes the extracellular matrix protein fibrillin‐1. Patients with MFS are predisposed to aortic aneurysms and dissections, significantly contributing to mortality. Emerging evidence suggests that endothelial cell (EC) senescence plays a critical role in the pathogenesis of aortic aneurysms in MFS. This study aims to elucidate the role of EC senescence in the development of aortic aneurysms in MFS using a vascular model derived from human induced pluripotent stem cells. Methods and Results We generated human induced pluripotent stem cells lines from 2 patients with MFS carrying specific Fibrillin‐1 mutations and differentiated these into ECs. These MFS–hiPSC‐derived ECs were characterized using immunofluorescence, reverse transcription‐quantitative polymerase chain reaction, and Western blotting. Functional assays including cell proliferation, scratch wound, tube formation, NO content detection, and senescence‐associated β‐galactosidase staining were conducted. RNA sequencing was performed to elucidate underlying signaling pathways, and pharmacological inhibition of the transforming growth factor‐beta pathway was assessed for its therapeutic potential. MFS–hiPSC‐derived ECs recapitulated the pathological features observed in Marfan aortas, particularly pronounced cellular senescence, decreased cell proliferation, and abnormal transforming growth factor‐beta and NF‐κB signaling. These senescent ECs exhibited diminished proliferative and migratory capacities, reduced NO signaling, increased production of inflammatory cytokines, and attenuated responses to inflammatory stimuli. Importantly, senescence and dysfunction in MFS‐hiPSCderived ECs were ameliorated by transforming growth factor‐beta signaling pathway inhibitor, SB‐431542, suggesting a potential therapeutic strategy. Conclusions This study highlights the pivotal role of endothelial cell senescence in the pathogenesis of aortic aneurysms in MFS. Our human induced pluripotent stem cells–based disease model provides new insights into the disease mechanisms and underscores the potential of targeting the transforming growth factor‐beta pathway to mitigate endothelial dysfunction and senescence, offering a promising therapeutic avenue for MFS. |
