Key result

Circulating osteogenic precursor cells were identified in areas of calcification in human calcifying aortic valves, providing evidence for their role in the development of osteogenesis.

Implication

Hypothesis-generating for circulating precursors in valvular calcification; leaves open whether targeting them modifies disease progression.

Structured PICO

P
Population
Human calcifying aortic valves
C
Comparator
Unaffected calcified tissues
O
Outcome
Presence and localization of circulating osteogenic precursor cells (COP)surrogate

This editorial highlights the first evidence that circulating osteogenic precursor cells are present in human calcifying aortic valves and play a role in the cellular mechanisms of osteogenesis.

Limitations

  • No consistent involvement of the valve leaflet layers as the areas of endochondral ossification were found to extend to variable depths

Cite This Study

Nalini M. Rajamannan (2011) conducted an editorial in Calcific aortic valve disease. Circulating osteogenic precursor cells (COP) vs. Unaffected tissues was evaluated on Presence of COP cells in areas of calcification. Circulating osteogenic precursor cells were identified in areas of calcification in human calcifying aortic valves, providing evidence for their role in the development of osteogenesis.
