Benefits of live cell research
Live cell imaging is a fundamental research tool in cell biology labs and in a wide variety of industries, and it has led to the discovery of drug targets and candidates as well as the molecular mechanisms involved in diseases. Critical for these researchers, is the ability to develop assays that can best mimic the in vivo nature of cells. Benefits of imaging live cells include:
- Monitoring live cells over time provides more than a snapshot of what is occurring in the cells while allowing for the visualization of transient events that may be missed in end-point assays and revealing optimal time-points for end-point assays.
- Tight regulation of environmental conditions ensures that the cellular structures and processes being studied are in their native physiological state
- Imaging live cells in their natural state minimizes artifacts that can arise from other imaging techniques, such as cell fixation and immunostaining.
- The localization and transport of cellular biomolecules along with the progression of multiple pathways can be investigated simultaneously in real-time.
- Acquiring images laterally, axially, and temporally enables the generation of 4D images and data
- Live cell imaging of molecular dynamics generates qualitative and quantitative data that can’t be gained from other biochemical methods.
Cellular imaging and analysis workflow
Protocols for culturing, plating, and maintaining live cells will vary between different cell models however, the steps below outlines a generalized workflow for live cell assays.
-
Plate cells into labware of choice (chamber slides, dishes, microplates)
-
Treat cells – Perform cell treatments with desired compounds, RNAi, etc. if part of the assay workflow.
-
Stain for markers – If required, label cells with the desired fluorophores (fluorescent dyes, fluorescent protein – peptide fusions, etc.
-
Environmental controls – If the acquisition will take a long time or if the assay is a live cell time-lapse experiment (continuous or discontinuous), then enable full environmental control including gas, temperature, and humidity.
-
Acquire cell image – Place the plate into the automated imaging system and start acquiring your live cell images
-
Analyze cell image – Use cellular imaging analysis software to run quantitative analysis of live cell images
Live cell imaging system
Sophisticated live cell imaging systems provide the ability to regulate environmental conditions to maintain the health and viability of cells while monitoring molecular and cellular dynamics from the single cell to organismal level. From the study of fast-kinetic events to running long-term, time-lapse assays, automated live cell imaging provides the direct observation of dynamic biological processes and the ability to generate a wealth of cellular information
- Label-free, brightfield imaging to multi-color fluorescence imaging capabilities provide the flexibility necessary for the multitude of live cell imaging applications
- High-acquisition speeds allow for the examination of fast-kinetic events, such as calcium oscillation in cardiomyocytes.
- Robust focusing capabilities of automated live cell imaging instruments ensure the maintenance of optimum focus through the entirety of the acquisition, which is crucial for generating accurate live cell imaging data.
Applications and assays

Cell Migration Assays
The movement or migration of cells is often measured in vitro to elucidate the mechanisms of various physiological activities such as wound healing or cancer cell metastasis. Cell migration assays may be conducted in a controlled environment using live cell time lapse imaging. A "wound" in a confluent monolayer of cells growing in a microplate is created, either by manually creating a scratch or by utilizing special microplates that provide a uniform and reproducible cell-free zone. Monitor cell proliferation, wound healing, migration, and spreading using transmitted light or live cell-compatible fluorescence. These medium to high throughput assays may be used to compare the migration between cells treated with either inhibitory or stimulatory compounds.

PLATE CELLS
Plate adherent or suspension cells into the labware of choice including culture dishes, chamber slides, and microplates. Incubate the cells at normal culture conditions (i.e. 37°C, 5% CO2). For adherent cells, incubating the plated cells overnight will allow ample time for cell attachment and growth.

TREAT WITH COMPOUNDS
If necessary for the protocol, treat the cells with compounds of interest.
Compounds can be added to cells for minutes up to several days depending on the mechanism of action of the compounds and the biological re-sponse being investigated. For example, apoptosis or receptor internalization assays generally require shorter incubation periods while multiparametric cytotoxicity assays require longer periods. Longer compound treatments may require the replacement of compounds during incubation
STAIN FOR MARKERS
Live cells can be stained with a variety of fluorophores or transfected/transduced with constructs containing fluorescent protein – peptide fusions. Manufacturer instructions should be followed when staining. Stain-ing isn’t necessary for all live cell applications and label free imaging and analysis allows for the tracking and monitoring of cells in brightfield only.
