Engineered cell versus modified exosomes in cancer therapy

Cancer therapeutic development is the most challenging domain in cancer. Cell-based cancer therapeutics come up with promising effectiveness. This approach was also cell-modified for better targeting efficiency development. Cell engineering-based cancer therapeutic is a cutting-edge method in cancer therapy. Due to complications of this process, cost and post-treatment side effects, this phenomenon came into the question mark. In this scenario, extracellular vesicle (EVs) research introduces a cell-free cancer therapeutic approach. In the therapeutic aspect most used EVs, come from stem cells, plants, and engineered cells. Among several EVs populations, Exosomes are the most used worldwide cell-free therapeutic tool for ageing cancer. The most interesting facts about exosomes are the biocompatible, non-immunoreactive, cross-biological barrier, and non-toxic (depending on the parental cell's nature). In this article, we are exploring modified exosomes (biological or chemical) that create a remarkable outcome in cancer therapeutic development compared to engineered cell-based therapeutics. Hope, in the future, modified exosomes become an effective, affordable, and specific cancer-targeting precision medicine.
