Cellular Imaging and Analysis for 3D Cell Culture Applications and Assays

Development of more complex, biologically relevant, and predictive cell-based assays for compound screening is a primary challenge in drug discovery. The integration of three-dimensional (3D) assay models is becoming more widespread to drive translational biology. Higher complexity cell models have gained popularity because they better mimic in vivo environments and responses to drug treatment. Specifically, 3D cell cultures offer the advantage of closely recapitulating aspects of human tissues including the architecture, cell organization, cell-cell and cell-matrix interactions, and more physiologically-relevant diffusion characteristics. Utilization of 3D cellular assays adds value to research and screening campaigns, spanning the translational gap between 2D cell cultures and whole-animal models. By reproducing important parameters of the in vivo environment, 3D models can provide unique insight into the behavior of stem cells and developing tissues in vitro.

3D cell imaging and analysis workflow

Die Entwicklung von Quantifizierungs-Assays mit 3D-Zellkulturen ist zu einem attraktiven, investigativen Werkzeug für das Studium komplexer Biologie geworden. Weitere Verbreitung im Screening verhinderten bisher die Komplikationen mit der 3D-Zellbilderfassung und den Arbeitsabläufen in der Analyse. High-content, high-throughput tools for microscopy offer innovative and automated techniques for evaluating this complex biology. After the 3D cell culture is grown or transferred to an imaging microplate, cells can be treated with compounds and stained with the marker of choice. For acquisition, the ImageXpress automated imaging systems and our cellular imaging and analysis software provide the capability to screen and analyze these models within a single, integrated interface to dramatically reduce time to discovery.

Solution for 3D Acquisition

 

Acquire images for 3D assays

In recent years, there have been significant advances in automated microscopy and imaging for delivering more predictive, physiologically-relevant measurements for drug discovery and environmental toxicity applications. Implementation of more complex assays and 3D models requires high resolution to capture publication-quality images and data.

Confocal imaging provides a high signal-to-noise ratio by reducing out-of-focus light for crisper images to yield more cellular detail even within a thick sample. Watch the video to learn about high-throughput techniques on how to acquire images in 3D using the ImageXpress Micro Confocal system.

Solution for 3D Images

 

Analyze images for 3D applications

There are different types of image sets that may be generated even though your sample is 3D. A single plane may be sufficient or multiple planes may be acquired. When multiple planes are acquired, it’s useful to be able to analyze them individually or to analyze them after combining them into a single 2D projection. Ultimately, analysis of the entire 3D image may be the goal of the experiment. Watch the video to learn more about techniques for analyzing images from multiple z-planes as a 3D volume using MetaXpress software.

Advantages of 3D Cell Models

The main advantages of three-dimensional (3D) cell models include physiologically relevant and more closely represent tissue microenvironments, cell-to-cell interactions, and biological processes that occur in vivo. Now you can generate more predictive data by incorporating technologies of high-content imaging (HCI) systems and cell imagers like the ImageXpress system. By integrating with high-content imaging acquisition and analysis software like MetaXpress® software with the 3D Analysis Module, it can be used for further analysis, visualization, and assessment of 3D structures. Diese eine Schnittstelle wird es Ihnen ermöglichen, die Herausforderungen von 3D-Aufnahmen und -analysen zu meistern, ganz ohne Abstriche beim Durchsatz oder der Qualität der Daten, und wird Ihnen so Vertrauen in Ihre Entdeckungen schenken.

3D cell imaging and analysis workflow

The workflow of a 3D cell culture protocol is dependent on the type of cell model being cultured. The 3D cell imaging and analysis workflow depicted here is a generalized example of 3D spheroids in a 96- or 384-well flat or round-bottom microplate. Each step breaks down the process from cell culture to image analysis and highlights the instrumentation and tools needed to conduct the cell culture protocol including an automated high-content imaging system and cellular imaging and analysis software.

 

3D Cell Imaging & Analysis Workflow
 
Culture Spheroids

CULTURE SPHEROIDS

3D cell can be cultured directly in a ULA, round bottom plate to develop the typical spherical shape of a spheroid. Cells can also be grown in alternate labware like a petri dish, flask, or other microplate before transferring to an imaging microplate.

96 or 384 Well Plates

96- or 384- Well Plates

Most 3D cell cultures for high-content, high-throughput screening are run using 96- or 384-well microplates. ULA, U-shaped/round bottom microplates enable the spherical shape to form spheroids or spheroids can also be cultured in a flat-bottom microplate using hydrogels to simulate extracellular matrices (ECM). Optimized spheroid cell culture protocols for the ImageXpress® Micro Confocal High-Content Imaging System can use ULA, U-bottom 96- and 384-well plates with a one-step staining procedure that reduces assay time and minimizes variability.

Treat with compounds

TREAT WITH COMPOUNDS

After spheroid formation, compounds are added into the wells, and then incubated for one to several days, depending on the mechanism being studied. Generally, shorter durations are used to study apoptosis and longer durations for multi-parameter cytotoxicity studies. For drug treatments requiring a longer duration, compounds are refreshed periodically during incubation. The concentration of compounds and the incubation period is dependent on the desired protocol.

Stain for Markers

STAIN FOR MARKERS

After compound treatment is completed, stains are added directly to the media. Stains that require no washing can be used to avoid disturbing spheroids, but spheroids can be carefully washed even using automation, if necessary.
