Engineered MSC Aggregates with E/N-Cadherin and IL-6 Preconditioning for the Treatment of Systemic Sclerosis.

ABSTRACT: Umbilical cord-derived mesenchymal stromal cells (MSCs) transplantation is a promising therapy for systemic sclerosis (SSc) because of their distinctive antifibrotic and immunomodulatory properties. To enhance the effects of MSCs transplantation, novel engineered MSC aggregates preconditioned with human E/N-cadherin fusion protein (hE/N-cad-Fc) and interleukin-6 (IL-6) for SSc treatment are fabricated and named 3D-Cad/IL6-MSCs. These novel-engineered MSC aggregates possess tighter cellular cohesion and exhibit enhanced antiapoptotic, immunosuppressive, and proangiogenic capabilities according to transcriptomic analyses. Moreover, 3D-Cad/IL6-MSCs have improved immunoregulatory effects on peripheral blood mononuclear cells (PBMCs), CD4⁺ T cells, and CD8⁺ T cells in vitr
