Organ-on-a-chip model offers insights into premature aging and vascular disease

The new organ-on-a-chip device consists of a top fluidic channel and underlying vacuum channel, which mimics, upon pressure, the mechanical stretching that cells experience within blood vessels. The team found that cells derived from HGPS donors but not from healthy donors showed an exacerbated response to biomechanical strain, with an increase in markers of inflammation, which are strongly associated with vascular disease and aging.

"Vascular diseases and aging are intimately linked yet rarely studied in an integrated approach," the authors write. "Gaining a deeper understanding of the molecular pathways regulating inflammation during vascular aging might pave the way for new strategies to minimizing cardiovascular risk with age."
