Avenues for Innovation: The Latest in Cell-Line Engineering and Development

Plato wrote in ancient Greece that “our need will be the real creator,†which transformed over time into the English proverb, “Necessity is the mother of invention.†Advancements in medicine and biomanufacturing technology in 2020 have epitomized that idea. Even as technologies such as mRNA vaccines have rocketed into the public’s awareness, biomanufacturing experts have worked behind the scenes with renewed vigor spurred on by hard lessons from the pandemic. Cell-line development and engineering are no exception. Already undergoing a…

Increasing Expression Titers: New Technologies Could Help Other Cell Lines Catch Up to CHO

Fang Tian is a lead scientist and head of cell biology research and development at the American Type Culture Collection (ATCC) in Manassas, VA. She is a member of both the International Cell Line Authentication Committee (ICLAC) and the US technical advisory group for the ISO/TC276 technical committee. At ATCC, she oversees preparation, authentication, characterization, quality control, and cryopreservation of more than 3,400 accessioned animal cell lines and hybridomas in the cell biology general collection. She holds a PhD in…

Engineering Alternatives: Modern Technology Enables Expression System Developers to Think Beyond CHO Cells

Major biopharmaceutical companies are teaming up with academics and the Bill & Melinda Gates Foundation to develop new biomanufacturing cell lines and methods. The project — known as the AltHost Consortium — is exploring innovative ways to produce biologics and vaccines for clinical usage in diseases from diabetes to cancer. Lead researcher J. Christopher Love at the Massachusetts Institute of Technology (MIT) likens this precompetitive, open-access collaboration to the early days of the biopharmaceutical industry. “When biomanufacturing first emerged as…

Cell-Free Expression: A Technology with Truly Disruptive Potential

Bioprocess engineer Beatrice Melinek is a postdoctoral research fellow at University College London’s Future Targeted Healthcare Manufacturing (FTHM) Hub, where she focuses on the use of cell-free protein synthesis (CFPS) as a platform for distributed production of stratified biotherapeutics. Previously Melinek specialized in purification of viral vectors and vaccines, with an engineering doctorate (EngD) in biochemical engineering and postdoctoral experience in UCL’s hematology department developing a new chromatography-based analytical method for measuring empty and full adenoassociated virus (AAV) capsids. She…

Technologies and Innovations: A Discussion with Selexis SA

Pierre-Alain Girod is chief scientific officer (CSO) for Selexis SA. He holds a PhD in plant biochemistry from the University of Lausanne in Switzerland and completed a postdoctoral fellowship at the University of Wisconsin in Madison, WI, on the degradation of proteins by the ubiquitin pathway. Girod returned to Switzerland in 1993, where he discovered a family of sequences that are involved in the epigenetic regulation of genes. That discovery subsequently has been used to express therapeutic proteins in the…
