This work investigates the mechanism of calcium phosphate deposition in vascular smooth muscle cells, suggesting it is primarily passive.

This research aims to determine whether calcium phosphate deposition during vascular calcification is a passive or cell-mediated process.
Examined calcium phosphate deposition in fixed vascular smooth muscle cells and live cells.
Analyzed the effects of different concentrations of calcium and phosphate ions.
Utilized high-resolution transmission electron microscopy to evaluate cellular deposits.
Calcium phosphate deposition occurs in a cell-independent manner based on ion concentrations.
Bone marker expression increases only with calcium phosphate deposition.
Crystalline structures differ between live cells (more amorphous) and lysed cells (more crystalline).

Villa-Bellosta et al. (2010) studied this question.
