Human valvular interstitial cell (VIC) calcification was donor- and passage-dependent in osteogenic media (OM) but not passage-dependent in pro-calcifying media (PM). (A) Alizarin red calcification stain and quantification of human calcific aortic valve disease tissue-derived VICs in normal control media (NM) or PM at passage one (P1) and passage four (P4), or in OM (B). Quantification presented as dot plots, bar indicates group mean, and for the OM dataset dots are distinguished by calcification-prone (calcified in OM, indicated by red dots) and calcification-resistant donors (non-calcified in OM, indicated by blue dots). n = 9 donors/media condition, F, female; M, male; N.S., non-significant; *P < 0.05 analyzed by t-test.
