Metastasis. Exosomes drive premetastatic niche formation
Nature Reviews. Cancer
|June 23, 2012
Summary
Tumour cells release exosomes that help create a premetastatic niche, preparing distant sites for cancer spread. This finding is crucial for understanding and potentially blocking cancer metastasis.
Area of Science:
- Oncology
- Cell Biology
- Molecular Biology
Background:
- Tumorigenesis and cancer progression involve complex cellular interactions.
- Exosomes are small vesicles secreted by cells, implicated in intercellular communication.
Discussion:
- Tumor-derived exosomes play a significant role in modulating the microenvironment.
- These exosomes facilitate the formation of a premetastatic niche, aiding cancer cell colonization.
Key Insights:
- Exosomes secreted by tumor cells are key mediators of premetastatic niche formation.
- This process involves reprogramming the microenvironment at distant sites.
Outlook:
- Targeting exosome-mediated pathways could offer novel therapeutic strategies against metastasis.
- Further research into exosome composition and function is warranted to develop effective anti-metastatic treatments.

02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
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...

01:36Overview of Exosomes
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.

02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
01:26Stem Cell Niche
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...
