Three sequential groups of subjects were recruited in this study for: 1) skin squame collection; 2) tape strip collection; and 3) tape strip and skin biopsy collection in the aim of identifying the most optimal method for measuring the mRNA levels of skin biomarkers in tape strip samples.
The purpose of this study was to develop a non-invasive method to measure mRNA levels using tape stripping on the skin of patients with psoriasis and patients with atopic dermatitis.
