Deriving Mesenchymal Stromal Cells from Umbilical Cord Lining and Wharton’s Jelly: A Comparative Study of Extraction Methods and Culture Media

Mesenchymal stromal cells (MSCs) are multipotent, self-renewing progenitor cells that can differentiate into adipocytes, chondrocytes, and osteocytes (1). Cultured MSCs are plastic-adherent and spindle-shaped, and they express cell-surface markers CD44, CD73, CD90, and CD105, but not CD14, CD34, CD45, CD11b, CD79a, CD19, or HLA-DR (2, 3). First isolated from bone marrow (BM), human MSCs have been investigated extensively in clinical studies. MSCs also have been isolated from adipose tissue (4) and peripheral blood (5). Perinatal organs and tissues such as…

Using Cutting-Edge Tools to Optimize Cell-Culture Media Development

Although culture-media optimization accounts for a relatively small part of process development, selections made at that stage strongly influence overall bioprocess productivity. Yaron Silberberg (chief scientist at the Ajinomoto Genexine CELLiST Solution Center) joined BPI in July 2022 to present strategies for enhancing media performance. He focused on how emerging tools for statistical analysis and process control facilitate media development for cultures based on Chinese hamster ovary (CHO) cell lines. Silberberg’s Presentation Because materials applied during cell-line development are not…

Innovations in Cell Culture, Sensor Technology, and Process Control: Preparing for Industry 4.0

To celebrate the 20th anniversary of BioProcess International, industry suppliers were asked to respond to a questionnaire about the important technologies, trends, and manufacturing innovations that have shaaped their companies and the entire industry over the past two decades. What has been the most important scientific or technological innovation in the past 20 years of bioprocessing? I have been in the industry since the mid-1990s, and clearly the most significant evolution in biomanufacturing has been the widespread implementation of single-use…

Enabling High-Performing
Perfusion Cell Culture

At least one report estimates that by 2025, 35% of biologics will be manufactured using enhanced processes, particularly perfusion-based bioprocessing. Results of two innovations that support this need for enhanced processes are examined below. The Thermo Scientific HyPerforma DynaDrive Single-Use Bioreactor (SUB), the latest advancement in SUB technology, offers better performance than other bioreactors and scalability up to 5,000 L. Gibco High-Intensity Perfusion CHO Medium is formulated to provide exceptional performance and ease of use, with capability of sustaining >1…

Compounded Media Powder Streamlines Cell Culture Media Preparation Operations

Cell culture medium is critical to cell growth, metabolism, and protein expression. It provides for optimum pH, osmolality, and nutrients in an environment that is essential for cell survival, growth, and expression of proteins and/or metabolites and drug-substance modalities of interest (1). A complete medium typically contains basic nutrients such as carbohydrates, amino acids, lipids, salts, vitamins, trace metals, growth factors/hormones (e.g., insulin), antishear factors, and other chemicals that facilitate cell growth and protein expression and may stabilize recombinant protein…

Reducing Risk in Bioproduction with Facilities Equivalency

Providing consistency in cell culture media biomanufacturing is critical to supply continuity. Central to this is the development of redundancy and harmonization across a global manufacturing network. These unprecedented times have also highlighted the importance of strategizing for increased and unexpected demand. Read this Special Report to learn about the importance of equivalency and the strategies used to maintain this critical requirement at Gibco cell culture media manufacturing facilities. Fill out the form below to read the complete report and…

Using Peptones to Achieve Diverse and Demanding Bioproduction Goals

As bioproduction requirements advance, it is critical to have consistent, high-quality media and supplements that continue to meet evolving industry needs. Peptones have been successfully used in bioproduction applications for more than 30 years to meet diverse and demanding production requirements. Their unique nutritional profiles and usage flexibility make peptones ideal components for creating a robust bioprocess. This Special Report will demonstrate the benefits of peptones and how they can be used to enhance process performance and consistently yield a…

Ask the Expert: Cell Culture Media Analysis Using Handheld Raman Analyzers

In biopharmaceutical manufacturing, cell culture media supply critical nutrients and maintain pH and osmolality to optimize protein product yield. Because media composition and condition have a strong effect on final biologic product quality and production, biopharmaceutical companies monitor media for lot-to-lot variability. Stability testing for degradation due to light exposure, temperature changes, or shelf-life/time is possible with rapid spectroscopic methods. In an 8 October 2019 “Ask the Expert” webinar, O. Dean Stuart (product manager at Thermo Fisher Scientific) explained how…

Upstream: Make the Right Decisions for Your mAb

Bioprocess decisions made during upstream operations can be difficult to reverse at later, more costly stages of biologic manufacture. They even can require significant backtracking, wasting precious time, labor, and material. Read this Special Report to learn ways to optimize monoclonal antibody bioprocessing upstream. Specifically, you will learn about different tools that small and emerging biotechnology groups can use to ensure robust cell-line selection novel media formulations designed for intensified upstream processing in perfusion modes mixing and delivery solutions that…

Making Media a Priority: An Interview with Susan Riley of Advanced Bioprocessing

Susan Riley is vice president and general manager of Advanced Bioprocessing. It’s been a year since Thermo Fisher Scientific’s acquisition of the Advanced Bioprocessing business from Becton Dickinson (BD). Why did Thermo Fisher see the Advanced Bioprocessing (AB) business as a good fit with its life-science offerings? AB has a significant portfolio in premium supplements for cell culture and microbial fermentation. The AB business was seen as a good fit for several reasons: It goes hand-in-glove with Gibco media, for…
