Mesenchymal stem cells derived from patients with premature aging syndromes display hallmarks of physiological aging.

ABSTRACT: Progeroid syndromes are rare genetic diseases with most of autosomal dominant transmission, the prevalence of which is less than 1/10,000,000. These syndromes caused by mutations in the <i>LMNA</i> gene encoding A-type lamins belong to a group of disorders called laminopathies. Lamins are implicated in the architecture and function of the nucleus and chromatin. Patients affected with progeroid laminopathies display accelerated aging of mesenchymal stem cells (MSCs)-derived tissues associated with nuclear morphological abnormalities. To identify pathways altered in progeroid patients' MSCs, we used induced pluripotent stem cells (hiPSCs) from patients affected with classical Hutchinson-Gilford progeria syndrome (HGPS, c.1824C&gt;T-p.G608G), HGPS-like syndrome (HGPS-L; c.1868
