The promise of high-content screening is the acceleration of discovery by extracting as much relevant information as possible from cells. Nevertheless, a large percentage of high-content screens analyze only a small number of image-based properties. As a result, valuable information from precious cells and disease models is not utilized. As nearly all screening approaches require a nuclear counterstain such as Hoechst to facilitate segmentation, phenotypic profiling of the nuclei can offer new and additional perspectives on assays at no extra cost.
In this application note, we demonstrate an efficient cell-based workflow for the assessment of EGF treatment effects in a cellular model of human skin cancer.

Hepatic steatosis, a reversible state of metabolic dysregulation, is the first step in the progression of nonalcoholic fatty liver disease (NAFLD). It is characterized by excessive intracellular lipid accumulation and can progress to nonalcoholic steatohepatitis (NASH) and hepatocellular injury. Currently, there are no FDA-approved medicines to treat NAFLD or NASH, and the complex molecular and genetic mechanisms are not completely understood. To address this, Siobhan Malany, from the Conrad Prebys Center for Chemical Genomics in Florida, US, and colleagues developed a model of hepatic steatosis in functional human induced pluripotent stem cell-derived hepatocytes (hiPSC-Hep).
Accumulation of fat in liver cells, a process called steatosis, is a common health problem that has many possible causes. Nonalcoholic fatty liver disease (NAFLD) is a group of conditions caused by the buildup of fat in the liver, with some sources estimating that one in four people develop it in their lifetime. NAFLD, if left untreated, may progress to nonalcoholic steatohepatitis (NASH). Dr. Anissa A. Widjaja and colleagues recently examined the connection between interleukin 11 (IL-11) signaling and the development of liver disease.
Microbial biofilm formation has important implications for human health and disease.

This case study illustrates how PerkinElmer’s high-content imaging solutions are enabling therapeutic antibody development. Two steps in the workflow - the clonal B cell selection and the functional antibody characterization - rely on high-content screening using the Operetta® system.
The coupling of the Operetta system to a plate::handler workstation allows the running of plates both day and night, further increasing the throughput. In addition, the EnVision multimode plate reader and the JANUS Automated Workstation are essential parts of the workflow that contribute to the throughput of the process and reduce the variability of liquid handling steps.
One of the greatest challenges in multiple sclerosis (MS) therapy is the halting or reversal of the failure of remyelination in the brain in order to reverse disabilities in MS patients. This case study highlights the recent work of Dr. Paul Tesar and colleagues at the Case Western Reserve University School of Medicine, which could potentially lead to such novel treatments, as it aims to control the function of stem cells in the body and thereby to help the body repair itself.
This case study shows how a previously-described neuroprotection assay was easily and directly transferred to the Opera Phenix® high-content screening system, with a 4-fold decrease in acquisition time. In the assay, primary rat neurons are co-cultured on top of rat-derived astrocytes. To induce axon degeneration experimentally, NGF is withdrawn, leading to neuronal cell death, while astrocytes remain healthy. This can be captured by two readouts: the total axon area and the total number of nuclei. Neuroprotective drug candidates lead to an increase in the total axon area while keeping the number of nuclei (astrocytes) constant. Decreasing nuclei counts indicate a cytotoxic effect.

Whether you’re familiar with high-content screening, or a newcomer, you’ll need the right tools and strategies to overcome the challenges of using complex 3D cell models in such an assay. For example, growing consistent, reproducible 3D cultures can be problematic and imaging large, thick cell samples can be challenging, while managing the huge volumes of data generated is perhaps the most demanding aspect of all. In this article, we provide our top tips for running a successful high-content screening assay using a 3D cell model. Learn how you can: Generate uniform 3D cell models, Get the best quality images, Minimize imaging time and volume of data, Get deeper insights from your 3D cell model and Avoid unnecessary data transfer steps.
High-content assays using 3D objects such as cysts or organoids can be challenging from the perspectives of both image acquisition and image analysis. In this technical note we describe how to image and analyze epithelial Madin-Darby canine kidney (MDCK) cysts in 3D on the Operetta CLS™ high-content analysis system.
Multicellular 3D “oids” (tumoroids, spheroids, organoids) have the potential to better predict the effects of drug candidates during preclinical screening. However, compared to 2D cell monolayers, assays using 3D model systems are more challenging.
In this technical note we describe how to image and analyze solid spheroids in 3D using the Opera Phenix™and Operetta™CLS high-content screening systems and Harmony® 4.8 imaging and analysis software.
In drug discovery programs, multicellular spheroids have emerged as powerful tools to bridge the gap between in vitro cell culture models and in vivo tissues. However, one of the greatest challenges in higher throughput 3D imaging is the acquisition of images of solid spheroids, owing to the reduced light penetration.
One solution is to use optical clearing techniques, which can enhance the imaging depth in spheroids by removing lipid and protein molecules.
In this technical note, we compare different optical clearing strategies for 3D spheroids and quantify the clearing effectiveness and alterations in spheroid morphology, and demonstrate how to increase imaging depth in 3D spheroids by a factor of four.
Live cell imaging has gained importance within drug discovery over recent times, as researchers look for more meaningful insights into cellular behavior and function. However, setting up live cell experiments can be challenging, as temperature, CO2 and evaporation need to be controlled to ensure optimal cell growth conditions.

Automated image acquisition and analysis of tissue sections can be challenging owing to the inherent height variations throughout each specimen, and this can hinder their use in screening applications.
In this technical note we show how PreciScan™ intelligent image acquisition enables generation of accurate high-resolution images, overcoming issues caused by factors such as height variations in the specimen or varying positions of the tissue sections on the slides, while also significantly reducing the data volume and acquisition time.
Spinning disk confocal microscopy is a common tool for live cell microscopy and reduces background fluorescence from out of focus planes. However, for 3D imaging, confocal image quality can be limited by a phenomenon known as ‘pinhole crosstalk’ which can lead to blurred images in conventional spinning disk systems. The confocal scanning unit of the Opera Phenix™ High-Content Screening System provides an increased distance between pinholes to reduce the pinhole crosstalk, leading to improved 3D image quality. Learn more in our Technical Note.
The key parameters in high-content imaging - speed, sensitivity (or intensity) and resolution - cannot be optimized independently as altering one of them influences the others. For example, increasing the resolution by choosing a higher magnification requires imaging of more fields to maintain the same cell number – at the expense of speed; or increasing the fluorescence intensity can be achieved by increasing the exposure time – again at the expense of speed. Nevertheless, there is a way to overcome some of these obstacles and here, in this Technical Note, we explain why the choice of the objective lens is critical.

Today's drug discovery strategies require candidate compounds to fail early and cheaply in the discovery stage, rather than late and expensively in the clinical phase. Testing compounds early in physiologically relevant model systems and leveraging rich information from image-based screens are ways of focusing on those compounds that give rise to the right phenotypic changes without undesirable effects on the system.
