Atopic dermatitis-like symptoms in DNCB- and OVA-induced BALB/c mice improve following hUC-MSC-CM treatment. A Changes in skin lesions on the backs of DNCB-induced mice after treatment with hUC-MSC-CM. B Representative H&E staining photomicrographs of dorsal skin samples from mice in the three groups following DNCB induction; scale bar = 200 μm. C Changes in DNCB-induced skin lesions on the backs of mice following hUC-MSC-CM treatment. D Representative H&E staining photomicrographs of dorsal skin samples from mice in the three groups following OVA induction. Scale bar = 200 μm. E Changes in mouse IgE serum levels following hUC-MSC-CM treatment. F Body weight changes in mice of the two model groups
