a) Schematic of HGPS pathogenesis. Mutations of the LMNA gene, such as C1824T, lead to aberrant mRNA splicing and permanent farnesylation of lamin A, i.e., progerin, that accumulates at the nuclear periphery.

Red arrow indicates stretching direction. Scale bar, 50 μm. d) 16% mechanical strain leads to DNA double-strand breaks (H2A.X immunostaining) and a slight increase of senescence (β-galactosidase-induced fluorescence) of HGPS hiPSC-SMC. b-d) Reproduced with permission.[246] Copyright 2017, John Wiley and Sons.
