The endothelium lines the inner surface of all blood vessels representing an important tissue with vital functions to mediate tissue homeostasis. Tissue-tissue interfaces play a critical role throughout the human body where endothelial cells (ECs) contribute by creating vital barriers with tight and adherens junctions to regulate permeability of macromolecules and fluids while protecting and nourishing adjacent tissue. They are the most prominent cell type to experience physical forces of shear, stretch and strain through the laminar pulsatile nature of the bloodstream. Alterations in physiological flow profiles have a strong impact on EC pathology contributing to diseases like atherosclerosis and coronary heart disease as well as inflammatory conditions. Further, they are among the first cell types to interact with xenobiotics. Endothelial endocytosis and barrier regulation have profound impact on drug-tissue interactions. There is the need for technological innovations and improvements to study EC biology, EC-epithelial and EC-nanocarrier interactions in more complex settings that take physiological biophysical and biochemical cues into account. For this purpose, the Multi-Organ-Tissue-Flow (MOTiF) biochip has been invented and its design has been finalised during the beginning of this thesis. The objective was to develop handling and cellular seeding protocols for the biochip to establish more in vivo-like and more complex in vitro EC culture approaches. Within the scope of this thesis, the biochip has been characterised for perfused EC culture. Complex co-cultures with tissue resident macrophages and further with murine cortical spheroids present in liver sinusoidal structures and at the blood-brain barrier (BBB) have been established, respectively. Additionally, first applications under physiological parameters of shear stress have been made. The focus was on nanocarrier uptake profiles and microvascular endothelial barrier interaction.

Techniques for microfabricating intricate microfluidic structures that mimic the microenvironment of tissues and organs, combined with the development of biomaterials with carefully engineered surface properties, have enabled new paradigms in and cell culture-based models for human diseases. The dimensions of surface features and fluidic channels made accessible by these techniques are well-suited to the size scale of biological cells. Microfluidic Cell Culture Systems applies design and experimental techniques used in in microfluidics, and cell culture technologies to organ-on-chip systems. This book is intended to serve as a professional reference, providing a practical guide to design and fabrication of microfluidic systems and biomaterials for use in cell culture systems and human organ models. The book covers topics ranging from academic first principles of microfluidic design, to clinical translation strategies for cell culture protocols. The goal is to help professionals coming from an engineering background to adapt their expertise for use in cell culture and organ models applications, and likewise to help biologists to design and employ microfluidic technologies in their cell culture systems. This 2nd edition contains new material that strengthens the focus on in vitro models useful for drug discovery and development. One new chapter reviews liver organ models from an industry perspective, while others cover new technologies for scaling these models and for multi-organ systems. Other new chapters highlight the development of organ models and systems for specific applications in disease modeling and drug safety. Previous chapters have been revised to reflect the latest advances. Provides design and operation methodology for microfluidic and microfabricated materials and devices for organ-on-chip disease and safety models. This is a rapidly expanding field that will continue to grow along with advances in cell biology and microfluidics technologies. Comprehensively covers strategies and techniques ranging from academic first principles to industrial scale-up approaches. Readers will gain insight into cell-material interactions, microfluidic flow, and design principles. Offers three fundamental types of information: 1) design principles, 2) operation techniques, and 3) background information/perspectives. The book is carefully designed to strike a balance between these three areas, so it will be of use to a broad range of readers with different technical interests and educational levels.

This open access book presents recent advances in the pure sciences that are of significance in the quest for alternatives to the use of animals in research and describes a variety of practical applications of the three key guiding principles for the more ethical use of animals in experiments – replacement, reduction, and refinement, collectively known as the 3Rs. Important examples from across the world of implementation of the 3Rs in the testing of cosmetics, chemicals, pesticides, and biologics, including vaccines, are described, with additional information on relevant regulations. The coverage also encompasses emerging approaches to alternative tests and the 3Rs. The book is based on the most informative contributions delivered at the Asian Congress 2016 on Alternatives and Animal Use in the Life Sciences.

Microbial endocrinology represents a newly emerging interdisciplinary field that is formed by the intersection of the fields of neurobiology and microbiology. This book will introduce a new perspective to the current understanding not only of the factors that mediate the ability of microbes to cause disease, but also to the mechanisms that maintain normal homeostasis. The discovery that microbes can directly respond to neuroendocrine hormones, as evidenced by increased growth and production of virulence-associated factors, provides for a new framework with which to investigate how microorganisms interface not only with vertebrates, but also with invertebrates and even plants. The reader will learn that the neuroendocrine hormones that one most commonly associates with mammals are actually found throughout the plant, insect and microbial communities to an extent that will undoubtedly surprise many, and most importantly, how interactions between microbes and neuroendocrine hormones can influence the pathophysiology of infectious disease.
