Upcoming Ask the Expert Session

Using Intestinal Organoids for Intestinal and Stem Cell Research– Starts Monday!

Intestinal organoids provide a major advancement in the way we study intestinal and adult stem cell biology. When intestinal crypts containing LGR5+ intestinal stem cells (ISCs) are placed in a specialized medium that simulates the intestinal stem cell niche, the ISCs rapidly proliferate and differentiate into all of the major cell types found in the intestinal epithelium: Paneth cells, goblet cells, enteroendocrine cells, and enterocytes. Remarkably, these cells arrange themselves into a crypt-villus structure surrounding a functional central lumen, thus maintaining the stem cell pool while mimicking the physiology of the adult intestinal epithelium. The resulting organoids (or “mini-guts”) can be used for a variety of research applications.

As an in vitro system that is capable of providing in vivo insight, intestinal organoids signify an exciting new chapter for research. During this Ask the Expert session, Ryan Conder, Senior Scientist at STEMCELL Technologies, will be answering your questions about intestinal organoid culture, its research applications, and IntestiCult™ Organoid Growth Medium (Mouse), the first-ever complete, defined and serum-free medium for growing intestinal organoids from mouse intestinal crypts.

“Development Strategies for High-performing Perfusion Media”

March 24, 2015

Biomanufacturers are increasingly driven to develop innovative solutions for highly efficient and cost-effective processes. Integrated continuous processing, comprising production in a high-cell density perfusion culture coupled to a continuous capture step, is a potential solution to serve as a universal biomanufacturing platform.

In this webcast, an expert describes a structured approach for developing a perfusion medium from a combination of commercially available medium and feeds. The medium optimization resulted in a final process with a cell-specific perfusion rate of about 20 pL/cell/d, a decrease of more than 75% compared with the starting process conditions.

Learn how this methodology can be applied to other cell culture media to serve as a fast route to an efficient upstream perfusion process. When combined with a continuous downstream operation, the resulting overall process can meet many demands of tomorrow’s biomanufacturing.

Key Learning Objectives:

  • Understand technologies that enable modern perfusion cell culture.
  • Review a fast and convenient strategy for developing a high-cell density perfusion process for Chinese hamster ovary (CHO) cells based on commercially available cell culture medium and feeds.
  • Learn how design of experiments (DoE) can be used in a structured approach to decrease the cell-specific perfusion rate in an existing process.

 

“Designing the Most Cost-Effective Manufacturing Strategy for Allogeneic Cell-Based Therapies”

March 25, 2015

Learn the key bioprocess economic parameters to be considered when designing the manufacturing strategy for an adherent cell-based allogeneic product.

Developing the right industrialization strategy is critical to support a sustainable cell therapy development and commercialization program. Cell sources, stock management, and technology performance are some of the key parameters that determine the manufacturing scale required for specific product characteristics, supply chain, and business risk management.

Participants will learn:

  • Map the factors influencing your bioprocess scale.
  • Design optimized manufacturing strategies for allogeneic cell-based therapies.
  • Evaluate and select the most cost-effective technology according to the lot size.
  • Align process development to the product roadmap.
