Vascular calcification is an active pathological process, characterised by cellular dysregulation and subsequent changes to the extracellular environment. In vivo detection of vascular calcification is only possible late stage via computed tomography, and there is no single biomarker for detecting progression of vascular calcification. There is an unmet clinical need to determine progression of vascular calcification in vulnerable patients. This is especially needed in chronic kidney disease (CKD) patients where there is a correlation of cardiovascular disease with declining renal status. We hypothesised that the entirety of circulating components should be taken into consideration with vessel wall cells to determine real-time vascular calcification development. In this protocol we describe the isolation and characterisation of human primary vascular smooth muscle cells (hpVSMCs), and the addition of human serum or plasma to hpVSMCs in a calcification assay and analysis. The BioHybrid analysis of biological changes to in vitro hpVSMC calcification is reflective of in vivo vascular calcification status. We suggest this analysis can discriminate between CKD patient cohorts and has the potential for wider application for risk factor determination in CKD and the general population.
