Extracellular Vesicles (EVs) have emerged as potent mediators of intercellular communication, playing a crucial role in cell biology and offering promising therapeutic potential. This study explores the insights from cell biology that underpin the therapeutic applications of extracellular vesicles, shedding light on their diverse functions, biogenesis, and the mechanisms by which they can be harnessed for innovative therapeutic strategies. Extracellular vesicles are broadly categorized into exosomes, microvesicles, and apoptotic bodies based on their biogenesis and size. Exosomes are derived from endocytic compartments, microvesicles bud directly from the cell membrane, and apoptotic bodies are released during programmed cell death. This diversity in biogenesis reflects the complexity of EVs in cell biology.

Extracellular vesicles encapsulate a rich cargo of proteins, lipids, nucleic acids, and other bioactive molecules. These cargoes are selectively packaged, reflecting the cell of origin's physiological state. The diverse content of EVs contributes to their versatility in mediating various cellular functions. Extracellular vesicles serve as messengers in intercellular communication, facilitating the exchange of information between cells. They can transfer bioactive molecules, including proteins, RNA, and lipids, to recipient cells, modulating their biological activities and influencing cellular behavior. EVs play a vital role in immune regulation by modulating immune cell functions. They can either stimulate or suppress immune responses depending on their cargo and the cellular context. Immune cells utilize EVs to communicate and coordinate responses during immune challenges.

Extracellular vesicles contribute to tissue repair and regeneration by promoting cell proliferation, angiogenesis, and extracellular matrix remodeling. Stem cell-derived EVs, in particular, have shown therapeutic potential in enhancing tissue regeneration in various pathological conditions. The regenerative potential of extracellular vesicles has garnered attention in regenerative medicine. Stem cellderived EVs, containing regenerative factors, have shown promise in promoting tissue repair and regeneration. They can mimic the therapeutic effects of stem cells without the challenges associated with cell transplantation.

Extracellular vesicles are being explored as vehicles for targeted drug delivery in cancer therapy. By engineering EVs to carry therapeutic payloads, such as chemotherapy drugs or RNA molecules, researchers aim to enhance drug delivery to cancer cells while minimizing off-target effects. EVs have demonstrated therapeutic potential in neurological disorders by modulating neuroinflammation, promoting neuronal survival, and influencing synaptic plasticity. The ability of EVs to cross the blood-brain barrier makes them attractive candidates for delivering therapeutic agents to the central nervous system.

In cardiovascular diseases, EVs derived from cardiac cells or stem cells have shown therapeutic benefits. They can promote angiogenesis, reduce inflammation, and contribute to cardiac repair following injury. EVs offer a novel avenue for developing therapies to address cardiovascular pathologies. Standardizing isolation methods and characterizing the cargo of extracellular vesicles are ongoing challenges. Establishing reproducible techniques for EV isolation and defining their cargo composition are crucial steps for advancing their therapeutic applications. Ensuring the safety and efficacy of EV-based therapies is paramount. Further research is needed to understand the potential immunogenicity, biodistribution, and long-term effects of administered EVs in vivo.


Extracellular vesicles, with their diverse roles in cell biology, offer exciting prospects for therapeutic innovation across various medical fields. The insights gained from cell biology have unveiled the complexity of EVs and their potential to modulate cellular functions. From regenerative medicine to cancer therapy and neurological disorders, the therapeutic applications of extracellular vesicles continue to expand. Addressing challenges related to standardization and safety will be crucial for unlocking the full potential of extracellular vesicles as a novel class of therapeutic agents. As research progresses, the therapeutic landscape is likely to be reshaped by the promising capabilities of these tiny, cell-derived messengers.
