Why not combine the best of both phenotypic and 3D approaches for drug discovery? There is a resurgence in using primary phenotypic screening strategies as a more productive approach over conventional target-directed methods. Three-dimensional cell culture recapitulates normal and pathological tissue architectures, thus providing physiologically relevant models to study normal development and disease. Challenges remain, though, for high-throughput screeners as researchers must procure large numbers of identical 3D cell cultures, develop assays and obtain fast, automated readouts from these more complex assays. Join cell biologists, tissue engineers, assay developers, screening managers and drug developers at Cambridge Healthtech Institute’s Inaugural 3D Cellular Models conference as they discuss strategies to accelerate the identification of novel therapeutic leads.

APPLYING 3D MODELS FOR TOXICOLOGY RESEARCH

2:00 Chairperson’s Opening Remarks

Jeffrey Morgan, Ph.D., Professor, Medical Science and Engineering, Department of Molecular Pharmacology, Physiology and Biotechnology, Brown University


2:05 FEATURED PRESENTATION: 3D SPHEROIDS FOR INVESTIGATING DRUG UPTAKE, ACCUMULATION AND TRANSPORT

Jeffrey MorganJeffrey Morgan, Ph.D., Professor, Medical Science and Engineering, Department of Molecular Pharmacology, Physiology and Biotechnology, Brown University

In addition to recapitulating normal and disease phenotypes, the small 3D microtissues formed by multi-cellular spheroids also mimic the physical/ biological barriers to drug penetration that are significant contributors to a drug’s efficacy as well as toxicity. This talk covers the use of micro-mold technology to form long-lived designer spheroids and their use to quantify drug transport.

2:35 Engineered 3D Microsystems: Recapitulating in vivo Form, Function and Responses

Christopher S. ChenChristopher S. Chen, M.D., Ph.D., Professor, Biomedical Engineering, Boston University and Wyss Institute for Biologically Inspired Engineering, Harvard University

The 3D organization of cells defines the adhesive, mechanical and soluble microenvironment that ultimately governs cell phenotype. Understanding how forces, form and cellular function are related provides a mechanism for engineering 3D cultures that can more faithfully reproduce in vivo function. This presentation discusses both the underlying fundamental insights and examples of engineered cultures that have the potential for enhancing discovery, validation and safety studies.

3:05 When Time Is the Third Dimension: Combining Computer Simulation and Primary Tissue Cell Culture to Identify Tissue Stem Cell-Toxic Drug Candidates

James L. SherleyJames L. Sherley, M.D., Ph.D., Director, Asymmetrex, LLC

Screening out drug candidates that are toxic to tissue stem cells before conventional preclinical testing would accelerate drug development and reduce its high cost. Human tissue stem cell toxicity may also elude animal testing and lead to even more expensive failures due to intolerable toxicity in clinical trials or after marketing. AlphaSTEM is a new computer simulation technology for predicting tissue stem cell toxicity against any human tissue in a relatively inexpensive cell culture format.

ProQinase-Drug Discovery in Oncology3:50 Use of Co-Spheroids Systems for the Analysis of the Impact of Stromal Cells on Anti-Cancer Drug Activity

Ehlert_JanJan E. Ehlert, Ph.D., Head, Cellular Drug Discovery, ProQinase GmbH

In cancer treatment, stroma-derived microenvironmental cues are suspected to exert an adversary impact on anti-cancer drug efficacy. For taking such influences into account, we established a spheroid-based co-culture system for the analysis of compound effects on the proliferation of tumor as well as of stromal cells. This modular HTS-compatible assay system generates information on stroma-attenuated drug activity that may prove valuable in early drug development to focus on compounds that remain active under microenvironmental conditions.

John WikswoJohn P. Wikswo, Ph.D., Founding Director, Vanderbilt Institute for Integrative Biosystems Research and Education and Gordon A. Cain University Professor, Vanderbilt University

Organs-on-chips (OoCs) are beginning to recapitulate human physiology in compact, two- and three-dimensional tissue models that are more accurate than monolayer monocultures on plastic or matrix, and minimize the dilution of paracrine signals intrinsic to Petri-dish or well-plate culture. Refined OoC microfluidics and analytics are now enabling the study of organ-organ interactions, including physiological regulation and drug toxicity. The next step is to optimize insertion of coupled OoCs into the drug development pipeline.
