Mesenchymal Stromal Cells from the Epidermis and Dermis of Psoriasis Patients: Morphology, Immunophenotype, Differentiation Patterns, and Regulation of T Cell Proliferation

Figure 6

MSCs from the skin of patients with psoriasis show low immunoregulatory capacity. Cocultures were performed with PBMCs that were stained with CFSE and activated with PHA in the absence (proliferation positive control) or presence of MSCs that were derived from the dermis or epidermis of healthy or psoriatic skin (lesional and nonlesional areas). BM-MSCs were used as a positive control for immunoregulation. After 6 days of culture with cell-cell contact, CD3+ T cell proliferation was analyzed. (a) Representative histograms are shown. (b) Proliferative response percentage; the of 6 independent cocultures are shown. Statistically significant differences with .
