    Stem Cell Research and Regenerative Medicine

    With the potential to treat a wide range of disease, from organ damage to congenital defects, stem cell research and tissue engineering form the underlying basis of regenerative medicine. Significant advances in the science of skin regeneration, for example, have now made it possible to develop and grow artificial skin grafts in a lab for treatment of burn victims. Other therapeutic applications include the use of stem cells to treat and repair central nervous system diseases such as ischemia and cerebral palsy, cardiovascular diseases, as well as autoimmune diseases including type I diabetes.

    Analyzing ERK Signal Transduction in Live Cells Using a FRET-Based Biosensor

    Extracellular signal-regulated kinase (ERK) is a key component in the regulation of embryogenesis, cell differentiation, cell proliferation, and cell death. The ERK signaling pathway is altered in various cancer types and is frequently investigated as a target for therapeutic intervention. This application note describes how a live cell FRET assay to study ERK signaling was performed on the Operetta CLS™ high-content analysis system. The optimized design of the FRET-based biosensor, the high-quality imaging of the Operetta CLS system and the easy-to-use image analysis tools of the Harmony® software contribute to the robustness of the high-content assay.

    Vascular Imaging Probes For Oncology and Inflammation Using the IVIS Spectrum

    Optical-based in vivo imaging of vascular changes and vascular leak is an emerging modality for studying altered physiology in a variety of different cancers and inflammatory states. A number of fluorescent imaging probes that circulate with the blood, but have no target selectivity, have been used to detect tumor leakiness as an indication of abnormal tumor vasculature. Inflammation is also characterized by distinct vascular changes, including vasodilation and increased vascular permeability, which are induced by the actions of various inflammatory mediators. This process is essential for facilitating access for appropriate cells, cytokines, and other factors to tissue sites in need of healing or protection from infection. This application note investigates the use of three fluorescent imaging probes, to detect and monitor vascular leak and inflammation in preclinical mouse breast cancer models.

    Measuring FRET using the Opera Phenix High-Content Screening System

    Fundamental processes in living cells, such as apoptosis and signal transduction are controlled by proteins, often acting in concert with other protein partners through protein-protein interactions (PPIs). Inappropriate protein-protein recognition can fundamentally contribute to many diseases, including cancer. Therefore, inhibiting protein-protein interactions represents an emerging area in drug design.

    NIR Fluorescent Cell Labeling for In Vivo Cell Tracking (VivoTrack 680)

    Fluorescent dyes have been used for many years to label cells for microscopy studies, and a variety of dyes in the visible fluorescence spectrum are available to label different cellular compartments and organelles. Efficient delivery of the fluorophore to the cell without excessively modifying surface proteins or perturbing cell function is the major biotechnological challenge. In addition, researchers have taken on the challenge of in vivo imaging, focusing on near infrared (NIR) dyes that fluoresce in a spectral region better suited for in vivo imaging due to reduced background and higher tissue penetration.

    Imaging Bile Canaliculi in 3D Liver Microtissues using the Opera Phenix HCS System

    Analyzing transport of biliary metabolites is essential to predict pharmacokinetics and hepatotoxicity during drug development. A functional impairment of hepatobilary transporters, such as bile salt export pump (BSEP) and multidrug resistance-associated protein 2 (MRP-2), is strongly associated with an increased risk of cholestatic liver injury. Here, we describe a 3D high-content screening assay to study hepatobiliary transporter function in InSphero human liver microtissues. Confocal imaging and automated image analysis were used to quantify BSEP and MRP-2-mediated efflux of fluorescent substrates into bile canaliculi.

    Epifluorescence (2D) imaging of superficially implanted mouse tumor xenograft models offers a fast and simple method for assessing tumor progression or response to therapy. This approach for tumor assessment requires the use of near infrared (NIR) imaging agents specific for different aspects of tumor biology, and this Application Note highlights the ease and utility of multiplex NIR fluorescence imaging to characterize the complex biology within tumors growing in a living mouse.

  • Application Note

    Phenotypic Profiling of Autophagy using the Opera Phenix High-Content Screening System

    Cells constantly sense their environment and their response is a spatio-temporal summation of all signals. To maintain physiological stability, cells need to adjust to environmental changes, a process called homeostasis. One of the most important processes involved in maintaining homeostasis is autophagy, and its significance was recognized by the award of the Nobel Prize for Physiology in 2016 to Yoshinori Ohsumi for the discovery of its underlying mechanisms. Although this is not fully understood, it is believed that autophagy can prevent tumor development by degrading, for example, damaged organelles and protein aggregates.

    Imaging Hepatocellular Liver Injury using NIR-labeled Annexin V

    Drug induced liver injury (DILI) is a major reason for late stage termination of drug discovery research projects, highlighting the importance of early integration of liver safety assessment in the drug development process. A technical approach for in vivo toxicology determination was developed using Acetaminophen (APAP), a commonly used over-the-counter analgesic and antipyretic drug, to induce acute hepatocellular liver injury.

    Molecular imaging of tumor energy metabolism as an early indicator of anti-cancer drug efficacy in small animal models

    Targeted cancer therapy aims to block key signaling pathways that are critical for tumor cell growth and survival. The blockage eventually results in cell death via apoptosis and tumor growth suppression. Encouraged by the success in clinical development, many academic and pharmaceutical researcher are in active pursuit of the improvement of next generation targeted anti-cancer drugs. As a result, many new chemical and biological entities are emerging from initial screening of in vitro, in vitro and/or in silico selection processes. From the perspective of drug development, it poses a great challenge on the next stage of in vivo validation and demands a robust, accurate, and efficient method for assessment of these candidates in living animal models.
