Microfluidic enrichment of a target cell type from a heterogenous suspension by adhesion-based negative selection.

The enrichment or isolation of a selected type of cells in a heterogeneous suspension is challenging when the surface markers of these cells are not completely known. Here, we present a 3-stage arrangement of peptide-coated microfluidic channels that can recover a small number of adipose-derived stem cells (ADSCs) from a heterogenous suspension by negative selection depletion of the non-target cell types.
