The Claim
Valve interstitial cells isolated from calcified aortic valves spontaneously form mineralized nodules in culture without osteogenic stimuli, while valve interstitial cells from non-calcified aortic valves do not form mineralized nodules under the same conditions.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Cells taken from diseased heart valves form calcium deposits in a lab dish without any special triggers, while cells from healthy valves do not form these deposits under the same conditions.
See the scientific wording
Valve interstitial cells isolated from calcified aortic valves spontaneously form mineralized nodules in culture without osteogenic stimuli, whereas cells from non-calcified valves do not, indicating an intrinsic, persistent osteogenic phenotype in diseased tissue.
Bacteria in the heart valve release DNA that activates immune signals in valve cells, causing them to turn on a gene called osterix. This gene forces the cells to behave like bone cells, which then deposit minerals and form hard nodules even without any bone-growing signals.
What the research says
1 studyScientists found that cells from hardened heart valves turned into bone-like material all by themselves in a dish, while cells from healthy valves didn’t — this means the diseased cells have permanently changed to act like bone cells.
