doi: 10.1111/apha.70075
Figure Lengend Snippet: Glucose promoted extracellular matrix (ECM) calcification in primary human coronary artery smooth muscle cells (pSMC) concentration‐ and time‐dependently. pSMC were cultured in control (CM; 5.5 mM glucose) or calcium/phosphate (CaP)‐enriched media with 0, 5.5, or 25 mM glucose over 7 days. Mannitol served as osmotic control. (A) Representative images of ECM mineral accessed by Alizarin Red staining after treatment with glucose and mannitol in CM or CaP media for 1, 3, 5, and 7 days. Scale bars: 1000 μm. (B) Quantification of eluted Alizarin Red staining from the ECM from Figure . Two‐way ANOVA with Dunnett's post hoc test. * p < 0.05 compared to all other conditions at day 7. (C) Representative images of cell viability visualized with fluorescein diacetate (FDA) and propidium iodide (PI) dual immunofluorescence staining at day 7. Negative control: Permeabilized cells with 0.05% Triton X‐100. Phase contrast shows the mineral indicated by the arrow. Scale bars: 75 μm. (D) Cell viability assessed by AlamarBlue assay. pSMC were cultured with glucose and CaP media for 7 days. (E) Apoptosis at day 7. (F) Representative images of the mitochondria‐specific dye MitoTracker Red (red) and nuclear Hoechst staining (blue) at day 7. Scale bars: 75 μm. n = 3–4 in duplicates, each n represents an independent pSMC donor. Mean ± SD. One‐way ANOVA with Dunnett's post hoc test compared to 5.5 mM glucose control (CM), n.s.; not significant.
Article Snippet: Human primary coronary artery smooth muscle cells (pSMC, Promocell) were cultured in Smooth Muscle Cell Growth Medium 2 (Promocell) and supplemented with Smooth Muscle Cell Growth Medium 2 Supplement Mix (Promocell), consisting of epidermal growth factor (0.5 ng/mL), insulin (5 μg/mL), basic fibroblast growth factor‐B (2 ng/mL), 5% fetal bovine serum (FBS), and 1% penicillin–streptomycin (P/S).
