Book Description
Mammalian cell lines command an effective monopoly for the production of therapeutic proteins that require post-translational modifications. This unique advantage outweighs the costs associated with mammalian cell culture, which are far grater in terms of development time and manufacturing when compared to microbial culture. The development of cell lines has undergone several advances over the years, essentially to meet the requirement to cut the time and costs associated with using such a complex hosts as production platforms. This book provides a comprehensive guide to the methodology involved in the development of cell lines and the cell engineering approach that can be employed to enhance productivity, improve cell function, glycosylation and secretion and control apoptosis. It presents an overall picture of the current topics central to expression engineering including such topics as epigenetics and the use of technologies to overcome positional dependent inactivation, the use of promoter and enhancer sequences for expression of various transgenes, site directed engineering of defined chromosomal sites, and examination of the role of eukaryotic nucleus as the controller of expression of genes that are introduced for production of a desired product. It includes a review of selection methods for high producers and an application developed by a major biopharmaceutical industry to expedite the cell line development process. The potential of cell engineering approch to enhance cell lines through the manipulation of single genes that play important roles in key metabolic and regulatory pathways is also explored throughout.

Book Description
The completion of the Human Genome Project and the rapid progress in cell bi- ogy and biochemical engineering, are major forces driving the steady increase of approved biotech products, especially biopharmaceuticals, in the market. Today mammalian cell products (“products from cells”), primarily monoclonals, cytokines, recombinant glycoproteins, and, increasingly, vaccines, dominate the biopharmaceutical industry. Moreover, a small number of products consisting of in vitro cultivated cells (“cells as product”) for regenerative medicine have also been introduced in the market. Their efficient production requires comprehensive knowledge of biological as well as biochemical mammalian cell culture fundamentals (e.g., cell characteristics and metabolism, cell line establishment, culture medium optimization) and related engineering principles (e.g., bioreactor design, process scale-up and optimization). In addition, new developments focusing on cell line development, animal-free c- ture media, disposables and the implications of changing processes (multi-purpo- facilities) have to be taken into account. While a number of excellent books treating the basic methods and applications of mammalian cell culture technology have been published, only little attention has been afforded to their engineering aspects. The aim of this book is to make a contribution to closing this gap; it particularly focuses on the interactions between biological and biochemical and engineering principles in processes derived from cell cultures. It is not intended to give a c- prehensive overview of the literature. This has been done extensively elsewhere.

Book Description
Since the introduction of recombinant human growth hormone and insulin a quarter century ago, protein therapeutics has greatly broadened the ho- zon of health care. Many patients suffering with life-threatening diseases or chronic dysfunctions, which were medically untreatable not long ago, can attest to the wonder these drugs have achieved. Although the ?rst generation of p- tein therapeutics was produced in recombinant Escherichia coli, most recent products use mammalian cells as production hosts. Not long after the ?rst p- duction of recombinant proteins in E. coli, it was realized that the complex tasks of most post-translational modi?cations on proteins could only be ef?ciently carried out in mammalian cells. In the 1990s, we witnessed a rapid expansion of mammalian-cell-derived protein therapeutics, chie?y antibodies. In fact, it has been nearly a decade since the market value of mammalian-cell-derived protein therapeutics surpassed that of those produced from E. coli. A common characteristic of recent antibody products is the relatively large dose required for effective therapy, demanding larger quantities for the treatment of a given disease. This, coupled with the broadening repertoire of protein drugs, has rapidly expanded the quantity needed for clinical applications. The increasing demand for protein therapeutics has not been met exclusively by construction of new manufacturing plants and increasing total volume capacity. More - portantly the productivity of cell culture processes has been driven upward by an order of magnitude in the past decade.

Book Description
The application of CRISPR/Cas systems for programmable DNA manipulation has revolutionized the field of genome engineering. In addition to their use for cutting DNA, nuclease-dead versions of Cas proteins fused to different effectors are a powerful tool for cell engineering and synthetic biology. In this thesis, I will discuss two projects from my Ph.D., both demonstrating how Cas12a can be used for constructing next-generation genetic circuits in human cells. For my first project I developed a split Cas12a protein, which spontaneously re-assembles into a functional gene-activating effector when all components are present. Therapeutic cell engineering, in which cells are programmed to sense and respond to complex disease states, requires integration of information about the cellular environment and execution of a functional response only in response to the specified combination of inputs. By linking the expression of individual components of the split Cas12a system to different input signals, it forms the functional core of multi-input, multi-output logic circuits in mammalian cells. The system is highly programmable and can generate expandable AND gates, as well as incorporate NOT logic by using anti-CRISPR proteins as an OFF switch. For my second project I established a platform for parallel signal recording using a hyper-efficient Cas12a base editor. Biological signal recording enables the study of molecular inputs experienced throughout cellular history, by encoding a transient signal as a permanent, targeted DNA mutation that can be read out at a later time by sequencing. However, current methods are often limited in their ability to scale up beyond a single biologically relevant signal in mammalian contexts. This novel implementation of Cas12a for signal recording provides a powerful platform for scalable recording, demonstrated by the recording of up to four signals in parallel in human cells. This method is plug-and-play with diverse inputs in different cell types, including tumor antigen recording in CAR-T cells. It can also be easily extended for more sophisticated applications, such as time-delimited recording and dual recorder-effector cells. Overall, these two projects demonstrate the utility of Cas-based effectors in complex genetic circuits, for both understand-ing fundamental biological processes as well as constructing smarter cellular therapeutics.

Book Description
Integrating advances in molecular biology into bioprocesses presents a continuous challenge to scientists and bioengineers. This series is conceived to help meet this challenge. It examines and assesses the feasibility of new approaches for the modification of cellular function such as gene expression, protein processing, secretion, glycosylation, immortalisation, proliferation, and apoptosis as well as the systematic study of the metabolic genotype-phenotype relationship. The series provides detailed coverage of the methodology for improving cellular properties of cells used in the production of biopharmaceuticals, gene and cell therapies and tissue engineering. It also seeks to explain the cellular mechanisms underlying in vitro physiological activity and productivity. This volume, which is based on presentations at the `European Workshop on Animal Cell Engineering' held in Costa Brava, Spain, contains a collection of chapters relating to cellular function and modification by leading authorities in several different areas of basic research and the biopharmaceutical industry.

Book Description
The advantages of the baculovirus system are rooted in the properties of the virus and the host (insect, or cell lines derived from it). During the normal infection cycle, two forms of the virus are produced: an early budded virus (BY) form (Kost et al. , 2000), in which the viral DNA and structural proteins are surrounded by membrane derived from the infected cell; and a late occluded form (occlusion-derived virus, ODy), consisting of enveloped viral cores which are embedded in a crystal matrix of viral proteins. The principal component of the matrix is the abundantly expressed protein polyhedrin. The budded virus rapidly spreads the infection from cell to cell within the insect host, resulting ultimately in the complete liquefaction of the host, and release of occluded virus into the environment. The occluded form protects the released virus, allowing it to survive for long periods in the environment until ingested by another host. In the alkaline environment ofthe insect gut, the protective protein matrix is removed, and the life cycle is repeated. In insect cell cultures, only the BV form of baculovirus is required, and the polyhedrin gene may be replaced with the gene for the recombinant protein. An additional benefit of replacing or deleting polyhedrin is that it effectively makes the virus unable to survive outside the laboratory, an advantage in terms of environmental safety. The system is intrinsically safe to animals, being unable to replicate in species other than a limited range of insects.
