Exosomes derived from mesenchymal stem cells (MSC-Ex) possess remarkable pro-regenerative properties for wound healing. Despite their potential, the challenge of mass production limits their clinical application. To address this, preparing exosome-like vesicles has become an international trend. In this study, 28 key microRNAs (miRNAs) with significant pro-proliferation, anti-inflammation, and anti-fibrosis functions were screened from MSC-Ex. These miRNAs were encapsulated into liposomes and then hybridized with extracellular vesicles derived from watermelon to create synthetic exosome-like vesicles. The fabricated vesicles exhibited similar particle size and zeta potential to MSC-Ex, demonstrating high serum stability and effectively resisting the degradation of miRNA by RNase. They were efficiently internalized by cells and enabled a high rate of lysosomal escape for miRNAs post cellular uptake, thereby effectively exerting their pro-proliferative, anti-inflammatory, and anti-fibrotic functions. Further experiments demonstrated that these vesicles efficiently accelerated burn wound healing and reduced scarring, with effects comparable to those of natural MSC-Ex.

This study systematically elucidated the mechanism of faba bean-wheat intercropping and Si-NPs regulating faba bean growth under Cd stress using rhizosphere metabolomics and 16 S rRNA microbiome analysis. The results showed that IFcd and IFcd + Si treatments significantly reduced Cd accumulation by 17.3% and 56.2%, and Fusarium wilt incidence by 11.1% and 33.3%, respectively, compared with monoculture faba bean (MFcd) while promoting root and plant growth.

First, the mechanism underpinning dialysate purification was corroborated based on micro-nanofluidics.
