Cardiovascular disease remains the leading cause of death worldwide, and much of the lab work behind new therapies depends on imaging. This post looks at how EVOS and high-content screening (HCS) platforms support cardiovascular and endothelial research in UK labs, with examples drawn from peer-reviewed studies that rely on fluorescence microscopy, live-cell imaging and quantitative image analysis.
Imaging cardiovascular biology at the cell level
Heart and vascular research often starts with cultured cells: endothelial monolayers, cardiac fibroblasts, induced pluripotent stem cell-derived cardiomyocytes, or vascular smooth-muscle cells. Researchers need to measure morphology, viability, proliferation, migration, calcium transients, mitochondrial function and responses to injury or inflammation. These assays generate large image datasets, which is why automated platforms such as the EVOS M7000 and CellInsight CX7 HCS systems are increasingly common in cardiovascular labs.
For routine fluorescence imaging — transfection checks, reporter expression, immunofluorescence staining — the EVOS M5000 and EVOS M7000 provide the brightfield, phase and LED fluorescence channels needed to quantify these phenotypes without tying up a confocal system.
Endothelial dysfunction and atherosclerosis models
Atherosclerosis begins with endothelial activation. In vitro models use tumour necrosis factor-α (TNF-α) or oxidised low-density lipoprotein (oxLDL) to trigger inflammatory adhesion-molecule expression in human umbilical-vein endothelial cells (HUVECs). Multi-channel fluorescence imaging on EVOS or HCS platforms lets researchers quantify ICAM-1, VCAM-1 and NF-κB nuclear translocation across replicate wells, giving reproducible dose-response data for anti-inflammatory candidates.
What is the main research question? How do endothelial cells respond to inflammatory and oxidant stress, and can candidate compounds reduce adhesion-molecule expression?
Which platform helps answer it? EVOS M5000/M7000 and CellInsight CX7 provide the multi-channel fluorescence imaging and well-plate throughput needed to quantify adhesion-molecule staining across many conditions.
Angiogenesis and tube-formation assays
Angiogenesis assays on Matrigel are a staple of cardiovascular and cancer-vascular biology. Endothelial cells form tube-like networks that researchers quantify for total tube length, branching points and mesh area. Live-cell EVOS systems can capture tube formation over several hours, while HCS platforms can automate the analysis of hundreds of images, reducing the variability that comes from manual tracing.
What is the main research question? How do endothelial cells assemble vascular networks in response to pro- or anti-angiogenic factors?
Which platform helps answer it? EVOS M7000 time-lapse imaging captures network formation dynamically, and HCS analysis tools extract tube-length and branching metrics reproducibly.
Cardiomyocyte phenotype and safety screening
Stem-cell-derived cardiomyocytes are used to model inherited cardiomyopathies and to screen compounds for cardiotoxicity. Researchers image sarcomeric organisation (α-actinin), calcium handling (GCaMP), mitochondrial membrane potential and cell death. High-content platforms can classify morphology across thousands of cells, while EVOS systems offer an accessible intermediate for smaller screens or method development.
What is the main research question? Can cultured cardiomyocytes reveal disease phenotypes or drug-induced toxicity at the cellular level?
Which platform helps answer it? EVOS fluorescence imaging validates staining and reporter expression, while CellInsight-class HCS scales the analysis for compound screening.
Platelet activation and thrombosis imaging
Platelet aggregation and spreading assays use fluorescently labelled platelets or calcium indicators to measure activation state. Widefield fluorescence microscopy — including EVOS platforms — is often sufficient for these experiments, especially when combined with automated image analysis to quantify platelet area, granule release markers or clot structure.
What is the main research question? How do platelets activate and aggregate under different conditions, and how can this be modulated?
Which platform helps answer it? EVOS systems provide the fluorescence imaging depth needed for platelet spreading and aggregation assays without requiring a confocal microscope.
Why this matters for UK labs
UK cardiovascular research spans academic groups, biotechs and contract research organisations. Many labs need imaging platforms that are straightforward to operate, easy to maintain and able to produce publication-ready quantification. Automated fluorescence systems reduce the bottleneck of reserving core-facility confocal time and make it practical to run larger, better-powered experiments.
For labs moving toward high-content screening, the path often starts with EVOS for assay development and staining validation, then scales to an HCS platform such as CellInsight CX7 for larger compound or genetic screens.

Frequently asked questions
Why are EVOS and HCS platforms useful for cardiovascular research?
They combine fluorescence imaging, multi-well automation and quantitative analysis, making it easier to study endothelial function, angiogenesis, platelet behaviour and cardiac cell phenotypes at scale.
Can EVOS microscopes image live endothelial cells over time?
Yes. EVOS models with environmental control and time-lapse capability can capture live endothelial-cell behaviours such as migration, tube formation and responses to inflammatory stimuli.
What is high-content screening in cardiology?
High-content screening uses automated microscopy and image analysis to measure multiple morphological or functional parameters across many samples, helping researchers identify disease mechanisms or test compounds.
