Multi Parameter Flow Cytometric Assessment of Regenerative Epidermis with Special Reference to the Antiproliferative Effect of Occlusion
Multi parameter flow cytometrical assays permit simultaneous assessment of proliferation, differentiation, and inflammation parameters. In this study, the validation of TO-PRO-3 iodide (TP3) compared to propidium iodide (PI) and DE-K10 compared to RKSE60 were evaluated in tape stripping induced hyperproliferation. No occlusion, Duoderm (intermediate occlusion) and Blenderm (maximal occlusion) were used as a model to evaluate the effect of occlusion on epidermal regeneration. Proliferation in the keratin 10-negative compartment measured with TP3 proved to be a good approximation of proliferation measured with PI. Other epidermal subpopulations (keratin 10-dim and -bright cells) did not make a relevant contribution to hyperproliferation. DE-K10 is probable more sensitive than RKSE60 to distinguish populations that differ in degree of differentiation. Occlusion of tape stripped skin resulted in decreased proliferation and increased differentiation. This effect was most pronounced with maximal occlusion. This study showed that occlusion is a therapy, which realises normalisation of hyperproliferative skin disorders.
