Extracellular vesicles (EVs) are heterogeneous populations of nano- and
micro-sized vesicles secreted by various cell types. There is mounting evidence
that EVs have widespread roles in transporting proteins, lipids, and nucleic
acids between cells and serve as mediators of intercellular communication. EVs
secreted from stem cells could function as paracrine factors, and appear to mimic
and recapitulate several features of their secreting cells. EV-mediated transport
of regulatory RNAs provides a novel source of trans-regulation between cells. As
such, stem cells have evolved unique forms of paracrine mechanisms for
recapitulating their potencies with specialized functions by transporting
non-coding RNAs (ncRNAs) via EVs. This includes the dissemination of stem
cell-derived EV-ncRNAs and their regulatory effects elicited in differentiation,
self-renewal, pluripotency, and the induction of reparative programs. Here, we
summarize and discuss the therapeutic effects of mesenchymal stem cell-derived
EV-ncRNAs in the induction of intrinsic regenerative programs elicited through
regulating several mechanisms. Among them, most noticeable are the EV-mediated
enrichment of ncRNAs at the injury sites contributing the regulation of matrix
remodeling, epithelial mesenchymal transitions, and attraction of fibroblasts.
Additionally, we emphasize EV-mediated transmission of anti-inflammatory RNAs
from stem cells to injury site that potentially orchestrate the resolution of the
inflammatory responses and immune alleviation to better facilitate healing
processes. Collectively, this knowledge indicates a high value and potential of
EV-mediated RNA-based therapeutic approaches in regenerative medicine.
