  • Bioprocess Technologies that Preserve the Quality of iPSCs
    Trends Biotechnol. (IF 13.747) Pub Date : 2020-04-05
    Ashli Polanco; Bingyu Kuang; Seongkyu Yoon

    Large-scale production of induced pluripotent stem cells (iPSCs) is essential for the treatment of a variety of clinical indications. However, culturing enough iPSCs for clinical applications is problematic due to their sensitive pluripotent state and dependence on a supporting matrix. Developing stem cell bioprocessing strategies that are scalable and meet clinical needs requires incorporating methods

    Conor M. O'Brien; Bhanu Chandra Mulukutla; Douglas G. Mashek; Wei-Shou Hu

    Mammalian cells are the main tool for the production of therapeutic proteins, viruses for gene therapy, and cells for cell therapy. In production processes cell metabolism is the main driver that causes changes in the growth environment and affects productivity and product quality. Of all nutrients, glucose has the most prominent impact on bioprocesses. We summarize recent findings on the regulation

    Mostak Ahmed,Kevin M Koo,Paul N Mainwaring,Laura G Carrascosa,Matt Trau

    Current biotechnological developments are driving a significant shift towards integrating proteomic analysis with landmark genomic, methylomic, and transcriptomic data to elucidate functional effects. For the majority of proteins, structure and function are closely intertwined. Post-translational protein modifications (e.g., phosphorylation) leading to aberrantly active structures can originate a wide

  • Elastin Biomaterials in Dermal Repair.
    Trends Biotechnol. (IF 13.747) Pub Date : 2019-12-21
    Qingyun Wen,Suzanne M Mithieux,Anthony S Weiss

    Wound healing has historically relied on endogenous processes, but engineered materials are increasingly being used to assist tissue repair. Elastin is an essential functional component of the dermal extracellular matrix and is an important part of skin wound repair that encompasses an elastic dermis. Advances in modern technology have better elucidated the specific signaling factors and cells that

  • Microdroplet-Assisted Screening of Biomolecule Production for Metabolic Engineering Applications
    Trends Biotechnol. (IF 13.747) Pub Date : 2019-12-10
    Emily K. Bowman, Hal S. Alper

    Success in synthetic biology and metabolic engineering is quickly becoming ‘test’ limited within the design–build–test cycle. Commonly used methods for high-throughput screening, including fluorescence-activated cell sorting (FACS) and microtiter plates, have intracellular product and throughput limitations. A growing alternative to these challenges is the use of microfluidic microdroplet-based methods

  • Cancer Immunoimaging with Smart Nanoparticles
    Trends Biotechnol. (IF 13.747) Pub Date : 2019-12-05
    Yu-Chuan Ou, Xiaona Wen, Rizia Bardhan

    Dynamic immunoimaging in vivo is crucial in patient-tailored immunotherapies to identify patients who will benefit from immunotherapies, monitor therapeutic efficacy post treatment, and determine alternative strategies for nonresponders. Nanoparticles have played a major role in the immunotherapy landscape. In this review, we summarize recent findings in immunoimaging where smart nanoparticles target

  • Next-Generation Sequencing: An Eye-Opener for the Surveillance of Antiviral Resistance in Influenza
    Trends Biotechnol. (IF 13.747) Pub Date : 2019-12-04
    Laura A.E. Van Poelvoorde, Xavier Saelens, Isabelle Thomas, Nancy H. Roosens

    Next-generation sequencing (NGS) can enable a more effective response to a wide range of communicable disease threats, such as influenza, which is one of the leading causes of human morbidity and mortality worldwide. After vaccination, antivirals are the second line of defense against influenza. The use of currently available antivirals can lead to antiviral resistance mutations in the entire influenza

  • Leveling Up Hydrogels: Hybrid Systems in Tissue Engineering.
    Trends Biotechnol. (IF 13.747) Pub Date : 2019-11-29
    Sara C Neves,Lorenzo Moroni,Cristina C Barrias,Pedro L Granja

    Hydrogels can mimic several features of the cell native microenvironment and have been widely used as synthetic extracellular matrices (ECMs) in tissue engineering and regenerative medicine (TERM). However, some applications have specifications that hydrogels cannot efficiently fulfill on their own. Incorporating reinforcing structures like fibrous scaffolds or particles into hydrogels, as hybrid systems

  • Unearthing Hidden Chemical Potential from Discarded Actinobacterial Libraries.
    Trends Biotechnol. (IF 13.747) Pub Date : 2019-11-27
    Marshall L Timmermans,Avena C Ross

    The redundancy of natural product biosynthesis in microbes poses a practical challenge for discovering new antimicrobial compounds from bacteria. The recent application of clustered regularly interspaced short palindromic repeats (CRISPR) technology by Culp et al. to inactivate the production of abundant antibiotics generates a metabolic clean slate for the detection and/or isolation of new and less

  • Gut Check Time: Antibiotic Delivery Strategies to Reduce Antimicrobial Resistance
    Trends Biotechnol. (IF 13.747) Pub Date : 2019-11-19
    Stephen A. Kelly, Aoife M. Rodgers, Séamus C. O’Brien, Ryan F. Donnelly, Brendan F. Gilmore

    Antimicrobial resistance (AMR) has developed into a huge threat to global health, and reducing it is an urgent priority for public health authorities. The importance of a healthy and balanced gut microbiome has been identified as a key protective factor against AMR development, but this can be significantly affected by antibiotic therapy, resulting in dysbiosis and reduction of taxonomic richness.

  • Hands-On Introduction to Synthetic Biology for Security Professionals
    Trends Biotechnol. (IF 13.747) Pub Date : 2019-07-15
    Neil R. Adames, Jenna E. Gallegos, Sonia Y. Hunt, William K. So, Jean Peccoud

    The rapid pace of life sciences innovations and a growing list of nontraditional actors engaging in biological research make it challenging to develop appropriate policies to protect sensitive infrastructures. To address this challenge, we developed a five-day awareness program for security professionals, including laboratory work, site visits, and lectures.

    Synthetic biology is a rapidly emerging interdisciplinary field of science and engineering that aims to redesign living systems through reprogramming genetic information. The field has catalysed global debate among policymakers and publics. Here we describe how synthetic biology relates to these international deliberations, particularly the Convention on Biological Diversity (CBD).
