Preclinical study reveals that reprogrammed stem cell-derived mesenchymal cells reduce skin fibrosis in a murine scleroderma model, highlighting a rejuvenated alternative to primary cell therapy.

Key Points

To determine whether mesenchymal stromal cells derived from reprogrammed adipose-derived stem cells exhibit enhanced anti-fibrotic and angiogenic potential compared to primary adipose stem cells in localized scleroderma.
Generated adipose-derived induced mesenchymal stromal cells (AD-iMSCs) from reprogrammed adipose-derived stem cells (ADSCs) and characterized senescence, proliferation, transcriptomic profiles, and conditioned media effects on angiogenesis and fibrosis markers.
Administered AD-iMSCs versus primary ADSCs in a bleomycin-induced murine localized scleroderma model to evaluate cellular persistence, dermal thickness, collagen density, and microvascularization.
AD-iMSCs exhibited lower senescence, greater proliferative capacity, and their conditioned medium stimulated significantly higher in vitro angiogenesis than primary ADSC medium.
In mice with bleomycin-induced scleroderma, AD-iMSCs demonstrated enhanced in vivo persistence, reduced dermal thickness and collagen density, and increased microvascular density compared to primary ADSCs.
AD-iMSC therapy exerted stronger down-regulation of TGF-β/Smad2/3 signaling and extracellular matrix remodeling cascades than primary ADSC treatment.
