  • Rescheduled: Multicellular Tumor Spheroids in HTS: New Assays Rescheduled: Multicellular Tumor Spheroids in HTS: New Assays Wojciech Senkowski Recorded: Feb 1 2017 50 mins
    Three-dimensional cell cultures, and multicellular tumor spheroids in (MCTS) in particular, have recently become a widely used tool for preclinical anticancer drug testing in high-throughput screening (HTS) setup. However, even though MCTS have been applied for HTS, their use has been limited to simple assays, such as assessing cell viability or inhibition of growth.

    This webinar will cover new approaches to MCTS-based HTS. It will present a new, robust viability assay, well-suited for HTS and based on green fluorescent protein (GFP) used as a surrogate marker of spheroid viability. It will also review a first-ever approach to obtain information-rich transcriptomic data from drug-treated MCTS on a large scale. In addition, the presenter will demonstrate how this novel platform resulted in the identification of previously unrecognized, context-dependent drug responses of cancer cells and in findings with potential clinical relevance.

    In summary, this webinar will demonstrate new ways of how MCTS-based HTS can be used to provide unique insights into context-dependent biology and cellular drug responses.

    About the Presenter:

    Wojciech Senkowski will soon complete his Ph.D. in Medical Sciences at Uppsala University, Sweden.

  • Current Trends in 3D and Organoid Cell Culture for Cancer Research Current Trends in 3D and Organoid Cell Culture for Cancer Research Marshall Kosovsky, Ph.D., Ömer H. Yilmaz, M.D., Ph.D.,Wojciech Senkowski, Recorded: Oct 4 2016 67 mins
    Corning was pleased to have recently sponsored a GEN webinar highlighting the latest techniques for 3D cell culture in cancer research.

    The use of 3D cell cultures has been rising sharply in recent years from its initial introduction, over two decades ago. Because 3D cultures more accurately mimic the cellular environment, they can be used to study various forms of cancer by fostering the growth of organoids that replicate key properties of in vivo organ systems or the original tumors from which they were derived.

    In addition, many 3D cultures are amenable to large-scale drug screens for rapid detection of phenotypic or genetic changes associated with therapeutic compounds—an approach that opens the door for the use of 3D culture as an integral part of personalized medicine.

    In this GEN webinar, panelists discussed how the latest 3D cell culture methods have facilitated breakthroughs in their research projects.

    Panelists:
    Marshall Kosovsky, Ph.D., Global Scientific Support Manager for Corning Life Sciences, will give a brief introduction into advances in Corning’s 3D culturing solutions.

    Ömer H. Yilmaz, M.D., Ph.D., Assistant Professor of Biology at the Massachusetts Institute of Technology, will describe his work on how adult stem cells and their microenvironment adapt to diverse conditions within the context of tissue regeneration and cancer initiation through the use of ex vivo intestinal organoid assays.

    Wojciech Senkowski, Doctoral candidate in the Department of Medical Sciences at Uppsala University in Sweden, will discuss his current work, which looks for applications of various tumor spheroid models in high-throughput drug screening for ways to identify novel compounds that target these cell populations

  • In Vitro Characterization of Species Difference of OATP In Vitro Characterization of Species Difference of OATP Na Li, Ph.D. Recorded: May 25 2016 52 mins
    Organic anion-transporting polypeptides (OATPs) play an important role in hepatic uptake of a variety of clinically important drugs. The significant differences in OATP/Oatp-dependent drug transport between human and preclinical species presents a challenge for interspecies extrapolation of drug pharmacodynamics and pharmacokinetics. The assessment of the difference in hepatic uptake between species using an in vitro model is highly desired to support mechanistic studies and to understand the differences observed between species in vivo.

    The Corning® TransportoCells™ model has demonstrated significant value in terms of supporting in vitro assessment of drug interaction with SLC transporters in drug discovery and development. Recently, several animal species of Oatps were introduced into the Corning TransportoCells portfolio. This webinar will focus on the development of the newly available animal species and characterization of the differences in OATP/Oatp in substrate specificity and kinetics using this "thaw and go" model.
  • Specialized Applications Using the Corning® Spheroid Microplate Specialized Applications Using the Corning® Spheroid Microplate Hilary Sherman, Applications Specialist & Audrey Bergeron, Application Specialist Recorded: Apr 22 2016 47 mins
    Three-dimensional (3D) cell culture models, which offer significant improvements over traditional two dimensional monolayer cell culture in terms of maintaining morphological and functional characteristics of tissue, are increasingly being incorporated in drug discovery as model systems to study disease or for screening for chemotherapeutic efficacy or drug toxicity. This presentation will demonstrate the use of Corning® spheroid microplates to culture and assay spheroids in a rapid and highly reproducible format that enables the formation of a single multi-cellular spheroid, centered in each well.

    Corning spheroid microplates are multiple well, cell culture plates with opaque walls and unique clear, round well-bottom geometry that utilize the Corning Ultra-Low Attachment surface coating. The coating is hydrophilic, biologically inert and non-degradable. Representative data will be shown exhibiting the use of the spheroid microplate in more specialized assays including the formation of neurospheres from neural stem cells (NSCs), a valuable model to study neurogenesis and neural development, as well as analysis of NSC proliferation and migration. We will also demonstrate the formation of hepatospheres using Corning HepatoCells, an immortalized alternative to primary human hepatocytes, in combination with the SCREEN-WELL Hepatotoxicity library from Enzo Life Sciences for 3D hepatotoxicity screening. Finally, we will show the use of the Corning spheroid microplate to generate spheroids comprised of multiple cell types, demonstrating the impact that including multiple cell types in 3D assays can have on therapeutic outcome in a chemotherapeutic assay.

  • A New SLC Transporter Model to Study the Impact of OATP1B1 Genetic Variants A New SLC Transporter Model to Study the Impact of OATP1B1 Genetic Variants Na Li, Ph.D. Recorded: Nov 16 2015 48 mins
    The importance of genetic variations in drug transporters for drug disposition and response has been increasingly recognized in the past decade. The drug transporter organic anion transporting polypeptide 1B1 (OATP1B1) is genetically polymorphic and plays a major role in hepatic uptake of a variety of clinically important drugs. Predicting the pharmacokinetic effect of these genetic variants on the drug disposition is critical for understanding the inter-individual variations to drug efficacy and safety. Corning TransportoCells was introduced to support in vitro assessment of drug interaction with SLC transporter. Specially, the newly developed TransportoCells OATP1B1 SNPs, alongside with OATP1B1 wild type, offer an in vitro tool kit for studying the potential impact of genetic variants on drug PK.

    This webinar will focus on the development and characterization of the newly available TransportoCells OATP1B1 genetic variants, three animal species Oatp family members and other drug transporters of emerging importance in drug development.
