The automated CliniMACS Prodigy® Adherent Cell Culture process enables GMP-compliant human pluripotent stem cell (PSC) expansion in a closed system. This process covers the entire workflow, including coating of culture vessels, inoculation and culture of PSCs and media exchange, until harvest of the final cell products.
Establishment of PSC banks, including master cell banks and working cell banks, by expanding cells in a GMP-compliant environment is a vital step during the manufacturing processes of PSC-based cell therapies. The CliniMACS Prodigy Adherent Cell Culture process offers nine modules representing different workflow steps, such as coating, inoculation, culture, media change, and harvest, during cell manufacturing. These modules can be flexibly combined to automate the PSC expansion process while the GMP-compliant, single-use CliniMACS Prodigy Tubing Set 730 provides a closed and sterile environment for PSC cultures. External culture vessels can also easily be connected to extend manufacturing scalability, highlighting the CliniMACS Prodigy as a ready-to-use solution for GMP-compliant PSC banking.
Dr. Rafal Krol from CiRA Foundation is using the CliniMACS Prodigy Adherent Cell Culture process for GMP-compliant expansion of human induced pluripotent stem (iPS) cells at large scale. Learn more about his exciting work to expand hundreds of thousands of iPS cells to hundreds of millions in as little as two weeks in the attached scientific poster and webinar.
The Coating module of the CliniMACS Prodigy Adherent Cell Culture process can be used to coat the CliniMACS Prodigy chamber or external culture vessels with customized coating solutions prior to cultivation. Cryopreserved PSCs can be resuspended in the starting cell bag after which, based on the designed seeding density, cells can be inoculated in the CliniMACS Prodigy Chamber or external culture vessels using the Inoculation module.
The Culture module allows users to set up the cell culture conditions of the CliniMACS Prodigy Chamber, such as temperature and CO2 concentration. If external culture vessels are used, cells need to be cultivated in a separate incubator. During PSC expansion, the Media change module facilitates complete or partial medium change upon request.
GMP-compliant PSC expansion relies on the strong synergy of iPS-Brew GMP Medium and MACS® GMP Recombinant Human TGF-β1. MACS GMP Products are manufactured and tested under a quality management system (ISO 13485) and are in compliance with relevant GMP guidelines. They are designed following the recommendations of USP <1043> on ancillary materials, and offer consistent lot-to-lot performance.
When the desired cell confluency is reached, the Harvest module can be employed to dissociate the cells from the culture vessels, collect, and centrifuge them in the CentriCult™ Unit. Subsequently, cells can be resuspended in the desired medium and harvested in a target cell bag. If continuous cultures are required, the Inoculation module can be used again to re-plate the harvested cells in a new culture vessel.
An iPS cell clone was expanded either manually or with the CliniMACS Prodigy Adherent Cell Culture process in the iPS-Brew GMP Medium until passage three (p3). Afterwards, flow cytometric quality control analyses were applied using a MACSQuant® Analyzer. Immunophenotyping revealed that the PSCs expanded on the CliniMACS Prodigy expressed pluripotency markers (TRA-1-60, SSEA-4, SSEA-5, Oct-4, and Sox2) at comparable levels to the manually expanded cells. Meanwhile almost no expression of the differentiation marker SSEA-1 was observed in both groups.
StemMACS™ Trilineage Differentiation Kit, human was used to determine the differentiation potential of expanded PSCs. Immunophenotyping revealed that both the automatically and manually expanded PSCs can differentiate into cells from three different lineages including, CD144 or CD140b positive cells (mesoderm), CXCR4 and Sox17 double positive cells (endoderm), as well as Sox2 and Pax6 double positive cells (ectoderm).
Reliable in-process and quality control (IPC/QC) are indispensable for consistent cell manufacturing. The CliniMACS Prodigy Tubing Set 730’s integrated sampling pouches allow for safe separation and collection of the control sample during and at the end of the cell manufacturing process. With the MACSQuant Analyzers and our wide portfolio of lot-to-lot consistent REAfinity Recombinant Antibodies, Miltenyi Biotec provides standard solutions for flow cytometric IPC/QC analyses during the PSC banking process.
Express Modes, tools based on algorithms that make use of thousands of real data sets for processing, gating, and analysis of your samples, complement the MACSQuant Analyzer Family of flow cytometers and allow you to standardize and automate your flow cytometry processes. Customized Express Modes can be designed for your specific needs and processes. The MACSQuant Instruments and the MACS Flow Cytometry portfolio are for research use only.
