Abstract

Early detection and effective treatment are daunting challenges in the field of cancer biology. Ovarian cancer has emerged as a third-ranked health issue among women worldwide. In recent decades, there have been numerous pieces of evidence regarding ovarian cancer depicting a high-grade cellular transformation leading to selfrenewal, defining cancer stemness, aggressive growth, and distribution to other organs. Deregulated biological processes are activated, including the Wnt pathway, AKT/MAPK, and STAT3, in typical cells that turn down the governed cell division into uncontrolled expansion through cancer stem cell markers SOX2, CD133, CD44, CD117, and Aldehyde dehydrogenase, thereby suppressing the cell immune system and apoptotic activity. Currently, there has been the advent of innovative therapy for cancer known as “Exosomes,” which are nanovesicles secreted by all cells conveying nucleic acids, proteins, lipids, and carbohydrates to the recipient cells. The upper-hand use of exosomes is marked by their immune tolerability, stability, and systemic delivery to target cells, which will contribute to cancer therapy. In this analysis, we will focus on the behavior of cancer stem cells in the EMT mechanism that promotes ovarian cancer and discusses exosome-based therapeutic applications that require further research to prevent tumor growth.
