About the Presenter
Dr. Tamara Lekishvili received her PhD in biochemistry from Tbilisi State University, Georgia. Later she was awarded with the NATO scholarship and continued her research at Norwegian University of Science and Technology in neurobiology. After two dynamic post-doctoral positions at the University of Bath and University of Birmingham, she joined the LGC Group, were she is a certified flow cytometry specialist within the cell and molecular biology team. Her major research focus is developing novel cell-based assays using different flow cytometry applications.
Standardization of flow cytometry methods is required to support robust and reliable quality assessment of cells during bioprocessing. Fluorescent cell barcoding (FCB) overcomes some of the limitations of conventional flow cytometry methods with improved accuracy and data quality. However, measurement variability across instruments or between analysts remains a challenge that must be addressed.
A modified fluorescent cell barcoding method using fixable viability dye eFlour 506 has been developed that reduces the potential for such variation. Proof of principle has been demonstrated for multiplexed immunophentoypic analysis using cultured human mesenchymal stromal cells (hMSCs) exposed to a variety of bioprocessing conditions during cell expansion.
This approach, which can easily be transferred to a variety of cell types, represents a further step toward achieving the rigor and robustness required for quality assessment of bioprocessing of cell therapy products, allowing more subtle variations in marker expression levels to be confidently observed.
