The Role of Cancer Cell Lines in Modern Oncology Research

Cancer cell lines are pivotal tools in cancer research, providing invaluable insights into tumor biology, drug development, and treatment response. Derived from human tumors, these immortalized cell lines allow for the study of cancer mechanisms in a controlled laboratory environment. This article reviews the characteristics, types, and applications of various cancer cell lines, including their role in screening potential therapeutic agents and understanding cancer cell behavior. While they offer significant advantages in research, including reproducibility and ease of manipulation, limitations such as genetic drift and a lack of tumor microenvironment simulation must be acknowledged. This review underscores the importance of cancer cell lines in advancing cancer research and highlights the need for complementary approaches to fully understand the complexities of cancer.
