Skin sample collection. One skin sample was obtained from healthy donors (n = 5), while two biopsies were collected from each patient with psoriasis: one corresponding to a nonlesional area and the other to a lesional area (n = 30). The dermis and epidermis were isolated and processed individually to obtain adherent cells. Cells with a fibroblastoid morphology were harvested and analyzed to determine their distinctive MSC characteristics.
