“ Automated Reproducible Dendritic Cell Production

“ The current gold-standard method for generating DCs from monocytes has 11 laborious manual steps involving 15 hours of technician time. Steps include static culture and stimulation with cytokines contained in culture media using multiple T-flasks or well plates.

To address this manufacturing dilemma, market-leading Corning entered into an agreement with Flaskworks to commercialize MicroDEN, an automated fluidic system that allows for differentiation of monocytes into DCs utilizing continuous perfusion of differentiation media.

“Using an automated, perfusion-based process such as MicroDEN for dendritic cell production eliminates six manual steps, reduces the risk of contamination, and efficiently produces repeatable results in less time,” said Elizabeth Misleh, senior product line manager, bioprocess, at Corning Life Sciences. “It also eliminates the variability that can result from different levels of technician proficiency.”

The closed system provides consistent yields and requires only three hours of technician time during the week-long process (see figure). MicroDEN leverages the benefits of a polystyrene culture surface, similar to the manual method, to provide for removal of non-adherent cells. Up to 25 million DCs can be reproducibly generated per unit, an equivalent or greater yield than manual production.”
