Transforming Cancer Care with Oncosomes: Insight into Biogenesis, Functional Role, and Therapeutic Potential

Area of Science:

• Oncology
• Biotechnology
• Extracellular Vesicles

Background:

• Oncosomes are large extracellular vesicles released by tumor cells.
• They contain oncogenic proteins, nucleic acids, and lipids, facilitating tumor communication.
• Oncosomes are being investigated as potential drug delivery vehicles in cancer research.

Purpose of the Study:

• To review current knowledge on oncosome biogenesis, composition, and roles in cancer progression.
• To critically evaluate methods for oncosome isolation, characterization, and cargo loading.
• To discuss challenges and future perspectives for engineered oncosomes in cancer therapy.

Main Methods:

• Literature review of preclinical studies and existing methodologies.
• Analysis of oncosome biogenesis, molecular composition, and cargo transport.
• Evaluation of isolation and loading techniques (incubation, electroporation, sonication, etc.).

Main Results:

• Oncosomes possess large cargo capacity and biological compatibility for drug delivery.
• Current evidence is largely proof-of-concept from in vitro and animal models.
• Significant challenges include vesicle heterogeneity, low loading efficiency, and manufacturing constraints.

Conclusions:

• Engineered oncosomes offer a promising experimental platform for personalized cancer research.
• Addressing technical and translational barriers is crucial for clinical application.
• Further research is needed to overcome limitations in large-scale production and safety.
