| abstractText | The dermal mesenchymal stem cells (DMSCs) from psoriasis display higher expression level of epidermal growth factor-like repeats and discoidin I-like domains 3 (EDIL3), while EDIL3 can bind integrins, including alphavbeta3 and alphavbeta5, to regulate angiogenesis. To assess the role of EDIL3 derived from DMSCs of psoriasis (P-DMSCs) in angiogenesis, in vitro, EDIL3 of DMSCs from psoriasis was silenced by interfering EDIL3. Then the efficacy of silencing EDIL3 was tested by fluorescent flag, qRT-PCR and western blotting. And, in vitro, the relationship of EDIL3 in DMSCs with the angiogenesis of HUVECs were investigated through co-culture system. In vivo, EDIL3 recombinant protein was injected into IMQ cream-induced psoriasis-like skin lesions of mouse and EDIL3-associated tube formation were determined using Image J software. Our results showed the capacity of the adhesion, migration and tube formation of HUVECs in all psoriatic DMSCs groups were significantly higher compared with the control and si-EDIL3 groups (all P<0.05) in vitro. Moreover, under stimulated by EDIL3 recombinant protein, EDIL3-associated tube formation was dramatically elevated in vivo (P<0.01). In this study, EDIL3 could promote the adhesion, migration and tube formation of ECs and participant in the angiogenesis pathogenesis of psoriasis through affecting biological function on ECs both in vitro and in vivo. The results suggest a potential role of the critical pro-angiogenic factor EDIL3 in psoriasis therapy. |
