Engineering Cancer's Journey: Emerging Tools for Metastasis Modeling

Area of Science:

• Biomedical Engineering
• Cancer Biology
• Cell Biology

Background:

• Cancer metastasis, the spread of cells from a primary tumor, is responsible for most cancer deaths.
• Metastasis involves complex cellular processes including migration, invasion, circulation survival, and colonization.
• Disseminated tumor cells colonize distant organs, leading to organ dysfunction and fatality.

Purpose of the Study:

• To review the utility of bioengineered in vitro models for studying the full metastatic cascade.
• To discuss the potential of cancer bioengineering in complementing traditional animal models.
• To identify future developments needed for comprehensive and accessible in vitro metastasis models.

Main Methods:

• Review of current literature on bioengineering approaches to cancer metastasis.
• Discussion of the capabilities and limitations of existing in vitro models.
• Analysis of the requirements for in vitro models to recapitulate the complete metastatic process.

Main Results:

• Bioengineering tools offer promising avenues for creating sophisticated in vitro models of cancer metastasis.
• In vitro models can facilitate hypothesis testing, large-scale screens, and mechanistic studies of metastasis.
• These models have the potential to supplement animal studies and guide targeted research.

Conclusions:

• Cancer bioengineering is crucial for developing advanced in vitro models to study metastasis.
• Further development is needed to ensure these models fully recapitulate the metastatic cascade.
• Accessible and faithful in vitro models will accelerate cancer research and therapeutic development worldwide.
