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.
