Interests: 1. Integrating in vitro systems and quantitative methods and modeling to inform drug discovery and drug product development with focus on: a. Mechanistic absorption models; b. Translational DMPK, c. Disease-based models; 2. Integrating stem cell technology, tissue biopsy, co-culture techniques, microfluidics, and next-generation sequencing to develop microphysiological systems to investigate drug- and disease-related mechanisms affecting membrane integrity and predict drug absorption/disposition: a. Development of a segment-specific intestine-on-a-chip to investigate drug- and disease-related mechanism affecting intestinal membrane integrity (leaky gut), as well as transport-mediated kinetics and drug–drug interactions; b. development of a neurovascular unit-on-a-chip model to study drug penetration in the brain parenchyma and cerebrospinal fluid, as well as molecular and cellular underlying mechanisms in neurodegenerative diseases

Special Issue Information

Dear Colleagues,

Over the last decade, progress has been made on the development of microphysiological systems for drug discovery and development. These models can provide new insights into the physiology and mechanisms of disease, biomarker identification and evaluation, and elucidation of the mechanisms of adverse drug reactions. Robust evidence for scalability is also emerging in the field. These models are also amenable to investigate absorption, distribution, metabolism, and excretion (ADME) properties of new drugs. Single organ or multi-organ microphysiological systems can provide critical system parameters for improved physiologically based pharmacokinetic evaluations, making this a promising tool to inform decision making at early stages of development. In the future, successful application of MPS platforms that closely mimic human physiology may ultimately reduce the need for animal models to predict ADME outcomes and decrease the overall risk and cost associated with drug development.

This Special Issue serves to highlight and capture the contemporary progress and current landscape of applying microphysiological systems to inform drug discovery and development. We invite articles on all aspects of applying microphysiological systems to predict ADME-related properties, including assessing drug–drug interactions.

In recent years, microphysiological systems (MPS) have been developed to shorten the test period and reduce animal experiments for drug development. We examined cell sources for the liver-MPS, i.e., MPS mimicking liver function. For liver-MPS, liver-like cells with high liver functions are required. Cryo-preserved hepatocytes (cryoheps), the gold standard hepatocytes for in vitro drug development, present several disadvantages, including differences between lots due to individual donor variations or a limited cell supply from the same donor. As such, alternatives for cryoheps are sought. Hepatocyte-like cells derived from human induced pluripotent stem cells (hiPSC-Heps), hepatocytes derived from liver-humanized mice (PXB-cells), and human liver cancer cells (HepG2 cells) were examined as source candidates for liver-MPS. Gene expression levels of the major cytochrome P450 of hiPSC-Heps, PXB cells, and HepG2 cells were compared with 22 lots of cryoheps, and the activities of hiPSC-Heps were compared with 8 lots of cryopreserved hepatocytes. A focused DNA microarray was used for the global gene analysis of the liver-like characteristics of hiPSC-Heps, PXB-cells, cryoheps, and HepG2 cells. Gene expression data from the focused microarray were analyzed by principal component analysis, hierarchical clustering, and enrichment analysis. The results indicated the characteristics of individual hepatocyte cell source and raised their consideration points as an alternative cell source candidate for liver-MPS. The study contributes to the repetitive utilization of a robust in vitro hepatic assay system over long periods with stable functionality. Full article
