Fig 2: Enzyme-linked immunosorbent assay (ELISA) measurements of the levels of protectin (CD59), osteonectin (secreted protein acidic and rich in cysteine, SPARC), perlecan (heparan sulfate proteoglycan 2, HSPG2), and fibronectin (FN1) in the pre-centrifuged, serum-free cell culture supernatant (2000× g) from primary human coronary artery endothelial cells (HCAEC, top) and primary human internal thoracic artery endothelial cells (HITAEC, bottom) treated with Dulbecco’s phosphate-buffered saline (DPBS), magnesiprotein particles (MPP), primary calciprotein particles (CPP-P), or secondary calciprotein particles (CPP-S) for 24 h. Blue, violet, pink and red dots are for the DPBS, MPP, CPP-P, and CPP-S-treated cells, respectively. Each dot on the plots represents one measurement (n = 12 measurements per group). Whiskers indicate the range, box bounds indicate the 25th–75th percentiles, and centre lines indicate the median. p values are provided above boxes, Kruskal–Wallis test with Dunn’s multiple comparisons test.
