Various enzymatic or mechanical methods have been proposed in the past to dissociate cells from different solid tissues. An automated mechanical disaggregation device (Medimachine) has recently been proposed. Unfortunately, most of these techniques are associated with a high cellular damage and a low cell recovery and are difficult to apply to skin biopsies. In this paper, we propose a combined enzymatic and mechanical method based on Medimachine, useful for the isolation of skin infiltrating T-lymphocytes from small cutaneous biopsies. As this method is easy and allows for a more correct qualitative and quantitative cytofluorimetric analysis of the lymphocyte subsets, it may be useful in the immunophenotyping of cutaneous T-cell lymphomas.
