Vascular disease modeling using induced pluripotent stem cells: Focus in Hutchinson-Gilford Progeria Syndrome.

Induced pluripotent stem cells (iPSCs) represent today an invaluable tool to create disease cell models for modeling and drug screening. Several lines of iPSCs have been generated in the last 7 years that changed the paradigm for studying diseases and the discovery of new drugs to treat them. In this article we focus our attention to vascular diseases in particular Hutchinson-Gilford Progeria Syndrome (HGPS), a devastating premature aging disease caused by a mutation in the lamin A gene. In general, patients die because of myocardial infarction or stroke. Because the patients are fragile the isolation of a particular type of cells is very difficult. Therefore in the last 5 years, researchers have used cells derived from iPSCs to model aspects of the HGPS and to screen libraries of chemicals to retard or treat the disease.
