The Corning Scientific Seminar Series is a series of free, online technical presentations that provide novel tips, best practices and proven techniques to help advance your research. Delivered by scientists to scientists, these one-hour broadcasts offer useful information and tips for lab technicians and researchers.
Chimeric antigen receptor (CAR)-T cells, which are engineered to recognize target cell surface antigens expressed on tumor cells, have shown promise to affect complete remission in patients with B-cell malignancies. However, applying this approach to target solid tumors has resulted in adverse effects in clinical studies. Methods for testing different models of CAR-T cells in vitro can provide further insight into viable antigen targets. Historically, two-dimensional (2D) cell culture models have been used in drug discovery. However, more elaborate, three-dimensional (3D) cell culture models better mimic the in vivo tumor microenvironment and help bridge the gap between in vitro studies and clinical outcomes.
In this special joint webinar, panelists from ProMab Biotechnologies, DiscoverX, and Corning Life Sciences will present data on a high-throughput, easy-to-use, highly reproducible method for screening CAR-T cells in a 3D cell culture model by combining various technologies.

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.

Webinar: The Impact of Soluble Factors and Substrate on Cell Culture: Media Additives, Growth Factors, and Surface
From basal media with feeder layers or serum to highly defined recombinant growth factors, cytokine, and extracellular matrix, there are many ways to grow the same cell type. The choice is dependent on scale, cost, control, skill, and regulatory factors.
This webinar will cover:
- Different ways to grow the same cell type
- The actual material costs of various methods
- Methods used to optimize formulations

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.
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
This presentation describes critical factors for selecting microcarriers, as well as starting protocols to help you optimize the attachment and expansion of cells in spinner flask and bioreactor environments.
In addition, you’ll learn about new dissolvable microcarrier technology, which provides unique advantages for cells that cannot be easily separated from standard microcarriers.

As part of this role, she facilitates customer adoption of Corning products for specific applications through protocol development, on-site technical support, and in-house customer-driven projects.
Cell culture media is required for successful and reproducible research but the catalog is full of acronyms and various formulation tables. Classical mammalian cell culture media formulations are very diverse both in terms of the number available and the concentration of constituents. Additionally, each medium was designed for specific cell types and culturing conditions.
This webinar will cover:
•The composition, characteristics, environmental factors, and additional supplements required to create optimal conditions for growth and productivity.
•Determining the right formulation for your application.
•Serum usage and helpful tips for optimizing your culture conditions.

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.
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.
