By real-time deformability cytometry (RT-DC), we have introduced a high-throughput method for continuous mechanical single-cell classification of heterogeneous cell populations at rates of several hundred cells per second. Here, we demonstrate the extension of this method towards a multi-parameter biological assay where phenotyping is based on quantitative image analysis. Performing RT-DC on whole blood we highlight its potential to identify subsets in heterogeneous cell populations without any labelling and extensive sample preparation. We also demonstrate its capability to detect lineage-, source- and disease-specific mechanical phenotypes in primary human hematopoietic stem cells and mature blood cells. In summary, RT-DC enables marker-free, quantitative phenotyping of heterogeneous cell populations with a throughput comparable to standard flow cytometry.
