Cancer cell culture is a fundamental technique in cancer research, enabling researchers to study tumor biology, test potential therapeutic agents, and elucidate cancer cell behavior under controlled conditions. This article provides an overview of cancer cell culture techniques, their advantages and limitations, and the significant role they play in advancing cancer research and drug discovery. Cancer, a group of diseases characterized by uncontrolled cell growth, remains one of the leading causes of mortality worldwide. Research on cancer biology is essential to understand the mechanisms driving tumor progression and to develop new therapies. Cancer cell culture, which involves the in vitro growth and maintenance of cancer cells, has become an indispensable tool in the field of oncology. This technique provides a controlled environment to study cancer cells outside of a living organism, allowing researchers to investigate cellular processes, screen drugs, and develop novel therapeutic approaches. There are several types of cancer cell cultures used in research, each with distinct characteristics and applications. Primary cultures are derived directly from patient tumor tissues. These cells retain many of the features of the original tumor, including its genetic and phenotypic heterogeneity. Primary cultures provide a more accurate representation of the tumor’s characteristics but have limitations, such as a finite lifespan, difficulty in obtaining and maintaining stable cultures, and a high degree of variability. Established cell lines, such as HeLa, MCF-7, and A549, are widely used in cancer research due to their ease of maintenance, rapid proliferation, and longevity in culture. These cell lines are immortalized, meaning they can proliferate indefinitely in culture, providing a consistent and readily available resource. However, they may not fully represent the primary tumor’s characteristics, as they can acquire genetic and phenotypic changes over time. Unlike traditional two-dimensional (2D) cultures, three-dimensional (3D) cultures allow cells to grow in a more physiologically relevant environment. Spheroids and organoids are examples of 3D cultures that better mimic the structural and functional characteristics of tumors in vivo, including cell-cell interactions, extracellular matrix composition, and nutrient gradients. As such, 3D cultures provide a more realistic platform for studying cancer cell behavior and drug responses. Various techniques and systems are employed to support cancer cell growth and maintenance. The most common method is Monolayer Culture, where cells are grown in a single layer attached to a flat surface. While convenient and cost-effective, monolayer culture does not fully replicate the complex tumor environment. In suspension culture Some cancer cells, especially blood-derived ones, grow in suspension rather than attaching to a substrate. This is typical for cultures of hematologic cancers, such as leukemia and lymphoma. In Co-culturing cancer cells with other cell types, such as stromal or immune cells, allows researchers to study cell-cell interactions and the influence of the tumor microenvironment on cancer progression and response to therapies. Advanced techniques like bioreactors and microfluidic systems provide dynamic, controlled conditions for cell culture. Microfluidic systems, often called “organ-on-a-chip,” enable precise control over the cellular microenvironment, simulating blood flow, nutrient exchange, and mechanical forces that are present in vivo. Cancer cell culture is pivotal in several areas of cancer research. Cancer cell cultures are commonly used to screen potential anti-cancer agents by exposing cells to different compounds and measuring their effects on cell viability, proliferation and apoptosis. This high-throughput screening is vital for identifying promising therapeutic candidates. Cancer cells in culture can be genetically manipulated to study the effects of specific genes on cancer progression.
