Billion-Cell Hypoxic Expansion of Human Mesenchymal Stem Cells in BioBLU® 5c Single-Use Vessels

We demonstrate the success of large clinical-scale culture of human adipose-derived mesenchymal stem cells in an industrial single-use vessel at a 3.75-L working volume. The vessel provides a precisely regulated environment for the growth of stem cells under carefully controlled simulated physiological conditions. The monitoring of the cultures allowed us to accurately regulate their performance, optimizing their growth while at the same time demonstrating appropriate stem cell markers coupled with differentiation assays performed at the end of the culture period.…

One Billion Mesenchymal Stem Cells in an Eppendorf BioBLU 5c Single-Use Bioreactor at 3.75-L Scale

For BPI’s inaugural “Ask the Expert” webcast, Ma Sha (Eppendorf’s director of technical applications) fielded questions related to his upcoming poster presentation at IBC’s Single-Use Applications for Biopharmaceutical Manufacturing in Boston this month: “One Billion Mesenchymal Stem Cells in Eppendorf BioBLU 5c Single-Use Bioreactor 3.75-L Scale”. Eppendorf R&D Labs is formerly New Brunswick Scientific, which was acquired by Eppendorf in 2007. Sha’s Presentation Our focus recently had been large-scale stem-cell applications in bioreactors. We chose to work on mesenchymal stem…
