The tumor stroma, crucial for tumor growth and metastasis, evolves with cancer. It creates supportive niches for cancer cells at secondary sites, influencing disease progression and treatment strategies.
Area of Science:
- Oncology
- Cancer Biology
- Tumor Microenvironment Research
Background:
- The tumor stroma, comprising extracellular matrix and non-malignant cells, is vital for primary tumor characteristics.
- Tumor stroma evolves alongside genetic changes in cancer cells during tumor development.
Purpose of the Study:
- To elucidate the role of tumor stroma and metastatic niche formation in cancer progression.
- To understand how the stromal microenvironment influences disseminated tumor cell survival and metastasis.
Main Methods:
- Review and synthesis of existing research on tumor stroma and metastatic niches.
- Analysis of the dynamic interactions between cancer cells and their microenvironment.
Main Results:
- Tumor stroma dictates tumor growth, morphology, and invasiveness.
- Disseminated tumor cells rely on the stromal microenvironment at secondary sites.
- Primary tumors can induce pre-metastatic niches, and mature niches can reactivate dormant cells.
Conclusions:
- The concept of the metastatic niche and stromal progression is critical for understanding cancer metastasis.
- This understanding offers new avenues for cancer diagnosis, prognosis, and therapy.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Metastasis
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
