Adipose‐derived stem cells attenuate atopic dermatitis‐like skin lesions in NC/Nga mice

Abstract

There is an unmet need in novel therapeutics for atopic dermatitis (AD). We examined the effects of autologous adipose‐derived stem cells (ADSCs) on AD‐like skin lesions induced by the application of 2,4‐dinitrochlorobenzene (DNCB) in NC/Nga mice. Autologous ADSCs and ADSC‐conditioned medium (ADSC‐CM) were injected intralesionally three times. Clinical severity and histopathologic findings were compared in sham naïve control, saline‐treated, ADSC‐treated, ADSC‐CM‐treated, and 2.5% cortisone lotion‐applied animals. The severity index, skin thickness, mast cell number, as well as expression levels of thymic stromal lymphopoietin, CD45, chemoattractant receptor‐homologous molecule, chemokine ligand 9, and chemokine ligand 20 were significantly lower in mice treated with ADSC, ADSC‐CM, or 2.5% cortisone lotion.

Tissue levels of interferon‐ γ as well as serum levels of interleukin‐33 and immunoglobulin E levels were also decreased in those groups. We conclude that autologous ADSCs improved DNCB‐induced AD‐like skin lesions in NC/Nga mice by reducing inflammation associated with Th2 immune response and interferon‐γ.
