What is a cancerous tumoroid?

As cancer cells accumulate changes in their genetic makeup (mutations) and how genes are regulated (epigenetic alterations, red), they gradually relinquish the intricate controls that usually manage their behavior. This loss of control sets the stage for cells to multiply uncontrollably and adopt invasive characteristics, ultimately coalescing into tumoroids. These tumoroids are a significant menace to the body’s overall balance.

In the evolving landscape of oncology, the concept of “cancerous tumoroids” is gaining recognition, denoting irregular growths distinguished by their unregulated cell division and tendency to invade surrounding tissues. These growths prominently display the key indicators of malignancy, showcasing the capability to spread to distant sites through metastasis, thereby perturbing the usual arrangement of healthy tissues.

How to work with cancer cells in 3D cell culture

Two methods are commonly employed when creating cancer spheroids: Scaffold-Based Systems and Spheroids.

  • Scaffold-Based Systems: This technique utilizes scaffold materials like hydrogels, porous polymers, or natural extracellular matrix components (such as collagen or Matrigel). These scaffolds serve as supportive frameworks. Initially, cancer cells are combined with the scaffold material and then placed within a suitable culture vessel. The scaffold is a platform for cells to anchor onto and grow three-dimensional. Over time, cells proliferate into a 3D structure resembling the growth pattern of tumors in the body.
  • Scaffold-Free Systems: Organoids or spheroids are formed when cancer cells naturally aggregate into spherical clusters. This is achieved by culturing cells in suspension, meaning they are not attached to a surface.

Both approaches offer insights into cancer cell behavior in a more realistic 3D environment, enhancing our understanding of their growth and response to treatment. Scaffold-based systems provide a structured foundation for cell growth, while Scaffold-free systems involve cells uniting naturally in a suspended environment, akin to forming clusters resembling small tumors. These methods, including the innovative use of rotary bioreactors, contribute to our knowledge of cancer biology and therapeutic strategies.

How to work with cancer organoids in the ClinoStar

Utilizing the Clinostar for cancer tumoroid production enhances consistency, gas, and nutrient exchange in simulated microgravity conditions. This, in turn, allows for very long-term cultures (up to a year or more), providing a more accurate and informative platform for studying cancer cell behavior. The unique advantages of the Clinostar contribute not only to terrestrial cancer research but also offer insights into how cancer cells might respond in space-related contexts.

Using a rotary bioreactor, like the ClinoStar, gives scientists distinct advantages when producing cancer tumoroids. An example is that the controlled rotation of the ClinoStar promotes uniform cell aggregation, resulting in consistent tumoroid size and structure. The long-term culture allows the growth rate of the cancer cells to fall to that seen in cancers in vivo. These features ensure that experimental results are reliable, reproducible, and relevant.
