Automated Counterflow Centrifugal System for Small-Scale Cell Processing

Area of Science:

• Biotechnology
• Cellular Manufacturing
• Process Engineering

Background:

• Commercializing gene and cell therapies necessitates cost-effective and scalable manufacturing.
• Buffer exchange and product concentration are critical but often manually intensive steps early in development.
• Manual methods like dead-end centrifugation are laborious, expensive, and hinder scalability.

Purpose of the Study:

• To introduce a novel automated cell processing device for small- to medium-scale applications.
• To bridge the gap between manual cell processing and large-scale automated manufacturing.
• To provide a versatile protocol adaptable to various cell types and processes.

Main Methods:

• Development of a new automated cell processing device.
• Modification of flow rate and centrifugation speed for different cell types and processes.
• Comparison of automated processing with manual dead-end centrifugation.

Main Results:

• High cell recovery rates were achieved using the automated protocol.
• Processing times were significantly shorter compared to manual methods.
• Recovered cells maintained their proliferation capabilities post-processing.

Conclusions:

• The developed device offers an efficient and scalable solution for cell processing steps like buffer exchange.
• It serves as a modular component within closed manufacturing systems for cell formulation and cryopreservation.
• This automation addresses the limitations of manual processing in early-stage cell therapy development.
