Psoriasis, an inflammatory autoimmune skin disease, is characterized by scaly white or erythematous plaques, which severely influence patients’ quality of life and social activities. Mesenchymal stem cells derived from the human umbilical cord (UCMSCs) represent a promising therapeutic approach for psoriasis because of its unique superiority in ethical agreeableness, abundant source, high proliferation capacity, and immunosuppression. Although cryopreservation provided multiple benefits to the cell therapy, it also greatly compromised clinical benefits of MSCs due to impaired cell functions. The current study aims to evaluate the therapeutic efficacy of cryopreserved UCMSCs in a mouse model of psoriasis as well as in patients with psoriasis. Our results showed that cryopreserved and fresh UCMSCs have comparable effects on the suppression of psoriasis-like symptoms such as thickening, erythema, and scaling, and serum IL-17 A secretion in mice model of psoriasis. Moreover, psoriatic patients injected with cryopreserved UCMSCs had a significant improvement in the Psoriasis Area and Severity Index (PASI), Physician Global Assessment (PGA), and Patient Global Assessments (PtGAs) scores compared to baseline values. Mechanically, cryopreserved UCMSCs markedly inhibit the proliferation of PHA-activated PBMCs, type 1 T helper (Th1) and type 17 T helper (Th17) cell differentiation and secretion of inflammatory cytokines including IFN-γ, TNF-a and IL-17 A in PBMCs stimulated by anti-CD3/CD28 beads. Taken together, these data indicated that cryopreserved UCMSCs exhibited great beneficial effect on psoriasis. Thus, cryopreserved UCMSCs can be systemically administered as ‘‘off-the-shelf’’ cell product for psoriasis therapy. Trial Registration ChiCTR1800019509.
