Abstract:

BACKGROUND: Studies have found abnormalities in the biological activity and cytokine levels of bone marrow mesenchymal stem cells from psoriasis patients, while the biological activity of skin-derived mesenchymal stem cells from psoriasis lesions is rarely reported.  OBJECTIVE: To explore the influences of skin-derived mesenchymal stem cells from psoriasis lesions on T cell proliferation
METHODS: After isolation and culture, skin-derived mesenchymal stem cells from psoriasis lesions and normal controls were separately co-cultured with peripheral blood T cells. T cell proliferation was detected using MTT assay, and levels of epidermal growth factor and transforming growth factor β1 in cell supernatant determined using ELISA method.
RESULTS AND CONCLUSION: Skin-derived mesenchymal stem cells from both psoriasis lesions and normal controls significantly inhibited T cell proliferation (P < 0.05). Furthermore, skin-derived mesenchymal stem cells from psoriasis lesions exhibited a weaker inhibitory effect on T cell proliferation than normal skin-derived mesenchymal stem cells (P < 0.05). Skin-derived mesenchymal stem cells from psoriasis lesions significantly increased epidermal growth factor but reduced transforming growth factor β1 compared with the normal skin-derived mesenchymal stem cells (P < 0.05). In conclusion, maybe the imbalances of growth factor levels due to skin injury elicit a decrease in the inhibitory effect of skin-derived mesenchymal stem cells from psoriasis lesions on T lymphocytes.
