The samples were selected because they showed calcification associated with a range of different diseases. Samples were examined with routine stains as well as stains to show calcification and specific markers for endothelium and macrophages.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Our observations indicate that calcification develops via two main pathways: dystrophic and vascular. Dystrophic calcification results from membrane disruption and uncontrolled calcium entry into necrotic (dead) cells in ischaemia and infections. Vascular calcification appears to be initiated in protein globules, sometimes intracellular, but outside the endothelium of small vessels. One case with mutation of the occludin gene, implicating impaired endothelial integrity, showed this pattern, but identical vascular calcification was seen in other conditions, including Sturge\u2013Weber syndrome. Another form of vascular calcification involved the adventitia of arteries; the endothelium was always spared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Interpretation<\/jats:title><jats:p>Calcification in the developing brain that is not associated with tissue necrosis is initiated in cells associated with blood vessels. Calcium incrustation of blood vessels imposes rigidity, reduced vascular compliance, and altered permeability. This would explain associated atrophy, gliosis, and (in the developing brain) malformations of the cortex. Our findings suggest that pericytes initiate non\u2010dystrophic brain calcification, but further studies are needed to explore this possibility.<\/jats:p><\/jats:sec>","DOI":"10.1111\/dmcn.12493","type":"journal-article","created":{"date-parts":[[2014,5,21]],"date-time":"2014-05-21T05:28:52Z","timestamp":1400650132000},"page":"1009-1015","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Patterns
