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.

Recent developments in microfluidics have demonstrated enormous potential of microscale cell culture for biology studies and recognized as instrumental in performing rapid and efficient experiments on small-sample volumes. Microfluidic-based cell culture is an area of research that keeps growing and gaining importance as a prominent technology, able to link scientific disciplines with industrial and clinical applications. In particular, organotypic cell culture and its integration in microfluidic devices would enable the realization of “in vivo-like” cell microenvironment within systems that are more amenable to automation and integration. Such remarkable advancement forms the foundation and motivation to transfer research from the laboratory to the field. Although the microfluidics and cell culture technologies have influenced many areas of science, significant research efforts are currently focus on finding methods to transform drug screening and toxicity testing from a system reliant on high-dose animal studies to one based primarily on human-relevant in vitro models. In line with regulatory developments precluding the use of animal testing, as well as fundamental differences in animal versus human, human in vitro methodologies are required to replace the animal-based testes while permitting physiologically relevant model equivalents for superior prediction. Organs-on-a-chip is an ambitious and rapidly growing technology that promise to bridge the gap between in vivo and in vitro studies and open wide possibilities in medical and industrial applications. However, many challenges are still ahead. This eBook present recent state-of-the-art works and critical reviews in organs-on-a-chip technology which highlight the new advances in this growing field with an emphasis on the interface between technological advancements and high impact applications.

Microfluidic platforms are increasingly being used for separating a wide variety of particles based on their physical and chemical properties. In the past two decades, many practical applications have been found in chemical and biological sciences, including single cell analysis, clinical diagnostics, regenerative medicine, nanomaterials synthesis, environmental monitoring, etc. In this Special Issue, we invited contributions to report state-of-the art developments in the fields of micro- and nanofluidic separation, fractionation, sorting, and purification of all classes of particles, including, but not limited to, active devices using electric, magnetic, optical, and acoustic forces; passive devices using geometries and hydrodynamic effects at the micro/nanoscale; confined and open platforms; label-based and label-free technology; and separation of bioparticles (including blood cells), circulating tumor cells, live/dead cells, exosomes, DNA, and non-bioparticles, including polymeric or inorganic micro- and nanoparticles, droplets, bubbles, etc. Practical devices that demonstrate capabilities to solve real-world problems were of particular interest.

Microfluidics-based devices play an important role in creating realistic microenvironments in which cell cultures can thrive. They can, for example, be used to monitor drug toxicity and perform medical diagnostics, and be in a static-, perfusion- or droplet-based device. They can also be used to study cell-cell, cell-matrix or cell-surface interactions. Cells can be either single cells, 3D cell cultures or co-cultures. Other organisms could include bacteria, zebra fish embryo, C. elegans, to name a few.
