Study on the physicochemical properties of MSCs exosome-loaded viscous hydrogels and their mechanism of regulating angiogenesis
It is demonstrated that viscoelastic PEG–alginate hydrogels enhance the stability, cellular uptake, and pro-angiogenic efficacy of MSC-derived exosomes while providing cytoprotective effects, highlighting their potential as an effective delivery platform for angiogenesis-mediated regenerative therapies.
