Generation and Manipulation of Exosomes

Methods Mol Biol. 2021:2158:295-305. doi: 10.1007/978-1-0716-0668-1_22.

Abstract

Exosomes are membrane-bound nano-vehicles shed by most eukaryotic cells. Exosomes contain specific proteins and RNAs from parent cells, and they play key signaling roles in cellular development, modulation, and tissue regeneration. Attempts to isolate and modify exosomes to increase their targeting efficiency to specific tissue are still in their infancy. Here, we describe generation of exosomes from biopsy, isolation of exosomes by centrifugal ultrafiltration method, and approaches for manipulation of cardiac homing exosomes by chemical engineering for the treatment of myocardial infarction.

Keywords: Cardiac homing peptide; Exosome generation; Exosome manipulation; Intravenous injection; Myocardial infarction; Platelet membrane.
