Fast, Efficient, and Gentle Transfection of Human Adherent Cells in Suspension

Abstract

We demonstrate a highly efficient method for gene delivery into clinically relevant human cell types, such as induced pluripotent stem cells (iPSCs) and fibroblasts, reducing the protocol time by one full day. To preserve cell physiology during gene transfer, we designed a microfluidic strategy, which facilitates significant gene delivery in a short transfection time (<1 min) for several human cell types. This fast, optimized and generally applicable cell transfection method can be used for rapid screening of different delivery systems and has significant potential for high-throughput cell therapy applications.
