CD surface markers have long been used to identify immune cell subsets and associate cells with certain immune functions. Typically, flow cytometry and specific fluorescently-labelled anti-CD antibodies are used for these analyses. Whilst extremely powerful, this approach does not readily afford insight into temporal changes or spatial interactions between cell populations in heterogeneous systems.  Here we describe a novel labelling and analysis strategy to enable long-term, non-invasive quantification of immune cells based on IncuCyte® live-cell imaging.

An Fc-targeted anti-mouse Fab fragment conjugated to a green-emitting fluoroprobe (IncuCyte FabFluor-488) was used to tag antibodies to cell surface markers. Addition of the FabFluor488-antibody complex to living cells, including OptiGreen background suppressor, produced fluorescent labelling that was sufficiently bright and stable to allow repeated measurements for >4 days without perturbing cell morphology or growth. With new image analysis and visualisation tools, individual cells were segmented from the phase-contrast image and quantified cell by cell for fluorescence. The method was validated by comparing the phase cell counts over time with nuclear fluorescence values in proliferating Jurkat-Nuclight RFP cells.  In PBMCs, the anticipated frequencies of lymphocyte subpopulations (CD4, CD8, CD45) were detected using this method. Cell subsets can be gated for further analysis determining dynamic changes in response to stimuli, e.g. increase in CD71+ cells following anti-CD3/IL-2 activation.

FabFluor antibody labelling and live-cell imaging enables long-term tracking and analysis of immune cell subsets in living cultures over time. This method should prove powerful in analyses on dynamic heterogeneous cell models and for studying cell-cell interactions.
