A team of researchers has developed a novel delivery system for messenger RNA (mRNA) using extracellular vesicles (EVs). The new technique has the potential to overcome many of the delivery hurdles faced by other promising mRNA therapies. The researchers use EV-encapsulated mRNA to initiate and sustain collagen production for several months in the cells of photoaged skin in laboratory models. It is the first therapy to demonstrate this ability and represents a proof-of-concept for deploying the EV mRNA therapy.
