REVIEW HIGHLIGHT: Therapeutic Prospects of Extracellular Vesicles in Cancer Treatment

by   |  March 13, 2019

With the growing recognition that extracellular vesicles (EVs) are involved in modulating the tumor microenvironment, a number of labs are not only studying how EVs are involved in cancer biology but harnessing EVs for cancer treatments. A July, 2018, review delivers an excellent overview of the different strategies researchers are taking:

Chulpanova, DS, et al. Front Immunol. 2018 July 3; 9: 1534. PMCID: PMC6037714

 

What makes this review great:

Chulpanova, et al, discuss thirty-four different studies, organizing them by EV source—tumor-derived EVs, immune cell-derived EVs, and mesenchymal stem cell (MSC)-derived EVs—and whether the EV carries a cargo of anti-tumor small molecules, specific antigens, or small RNAs. Their summary table is an excellent and well-referenced resource for those interested in learning about all the different approaches.

Quote to Note:

“From priming the immune response to delivering ncRNAs and antitumor drugs, EVs provide a unique biological means of targeting tumors and their microenvironments, minimizing cytotoxic effects, and increasing the efficacy of treatments at lower drug doses…[although] progressing their use as therapeutic tools requires full characterization of such disadvantages and limitations before the promise of MVs in clinical practice is achieved.”

How SBI helped:

In their summary table, Chulpanova, et al., include the EV source cells for each study, as well as the purification method. Out of the thirty-four citations presented in the table, ExoQuick-TC was the most widely used commercial EV isolation method (used in six citations, Figure 1).

ExoQuick products are excellent alternatives to ultracentrifugation when it comes to isolating EVs—they are quick, provide clean, high-yield EV preps, and are compatible with small sample volumes and high-throughput workflows. See the data comparing ExoQuick ULTRA with ultracentrifugation here.

Other ways SBI can help:

While ExoQuick-TC is the most-used EV isolation reagent mentioned in the Chulpanova, et al., review, SBI has other products and services that support a complete EV workflow, from isolation and characterization to EV transfection and EV engineering.
