Abstract |
Exosomes are nano-vesicles which can transport a range of molecules including but not limited to proteins and miRNA. This ability of exosomes renders them useful in cellular communication often resulting in biological changes. They have several functions in facilitating normal biological processes such as immune responses and an involvement in pregnancy. However, they have also been linked to pathological conditions including cancer and pregnancy complications such as preeclampsia. An understanding for the role of exosomes in preeclampsia is based on the ability to purify and characterize exosomes. There have been several techniques proposed for the enrichment of exosomes such as ultracentrifugation, density gradient separation, and ultrafiltration although there is no widely accepted optimized technique. Here we describe a workflow for isolating exosomes from cell-conditioned media and biological fluids using a combination of centrifugation, buoyant density, and ultrafiltration approaches. |
