Abstract: The present invention provides compositions of yeast extracellular vesicles comprising biologically active molecules, methods for making the same, and methods for the use of the yeast extracellular vesicles to deliver biologically active molecules to target cells. In addition, the invention provides cells and compositions comprising the biologically active molecules and vesicles, which can be used as transfection reagents. The invention further provides methods for producing said compositions of biologically active molecules with vesicles as well as the cells that produce those compositions. Compositions and methods for delivering biologically active molecules, such as a small molecule, a DNA expression plasmid, an RNA molecule, a peptide, or a protein, to cells and/or tissues are provided.
