Type of stem cell may contribute to heart disease
San Francisco Chronicle

UC Berkeley scientists have discovered a type of stem cell that appears to lie dormant in blood vessel walls for decades before waking up and causing the arterial hardening and clogging that are associated with deadly strokes and heart attacks. The findings, published Wednesday in the journal Nature Communications, go against the prevailing theory on the cause of heart disease – that the smooth muscle cells that line blood vessels become damaged over time and are triggered to proliferate.
