Successful use of cell tracking dyes to monitor immune cell function and proliferation involves several critical steps. We describe methods for: 1) obtaining bright, uniform, reproducible label-ing with membrane dyes; 2) selecting fluorochromes and data acquisition conditions; and 3) choosing a model to quantify cell proliferation based on dye dilution.

This protocol describes the use of three different methods for analyzing cell proliferation in breast cancer cell lines. This includes the use of conventional cell counting, luminescence-based cell viability, and cell counting through the use of a cell imager. Each offers advantages for the reproducible measurement of cell proliferation.

Adhesion

Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules. Capillary action is a result of water’s adhesive tendencies. When a narrow glass...

Cells Coordinate Growth and Proliferation

Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

Integrins do more than anchor a cell to the extracellular matrix. Their engagement activates focal adhesion kinase and related signaling pathways, converting adhesive contact into intracellular growth-associated information. In cancer research, this connection helps explain how changes in the surrounding matrix may influence tumor-cell expansion and provides a mechanistic basis for studying adhesion-dependent proliferation.
Cadherins are important because they regulate cell-cell contacts and participate in growth control, complementing integrin-mediated interactions with the extracellular matrix. When adhesion signaling is altered, cancer cells may maintain proliferation while their normal contact relationships change. Comparing cadherin behavior with integrin and focal adhesion kinase signaling helps relate tissue organization to tumor progression.
Adhesion signaling can support sustained tumor-cell proliferation, but its disruption can also permit cells to detach from their original surroundings. That combination is significant in cancer biology because detachment can be associated with invasion and metastasis. Studying both growth and attachment states prevents proliferation measurements from being interpreted separately from changes in tumor-cell organization.
A useful model should represent more than cell number alone. Researchers can examine attachment to the extracellular matrix, cell-cell contacts, integrin-associated focal adhesion kinase signaling, growth, and evidence of detachment. Three-dimensional cultures are especially relevant because they reproduce the cellular environment more effectively, allowing adhesion and proliferation to be considered within a more tissue-like setting.
These studies can connect treatment-related changes with both tumor expansion and the adhesion systems that support it. By evaluating adhesion signaling, proliferation, and altered attachment behavior in a cancer model, researchers can assess whether a therapeutic response is accompanied by changes relevant to detachment, invasion, or metastasis. The approach links response measurements to disease progression.
Three-dimensional cultures matter because they better reproduce the cellular environment than a simplified setting. This context can preserve more relevant relationships among tumor cells, extracellular matrix, and cell-cell contacts, making it useful for examining how adhesion signaling relates to proliferation. Such models can strengthen studies of tumor progression and therapeutic responses by placing measurements in a more representative environment.
