Metastasis02:30

Metastasis

6.7K
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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.9K
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...

Area of Science:

  • Oncology
  • Biomaterials Science
  • Immunology

Background:

  • The pre-metastatic niche, characterized by immune cells and extracellular matrix proteins, prepares organs for cancer cell colonization.
  • Understanding the complex interactions within the niche is crucial but challenging.
  • Existing experimental models struggle to fully recapitulate niche biology and tumor cell homing in vivo.

Purpose of the Study:

  • To review the biology of the pre-metastatic niche.
  • To discuss advances in engineered niche-mimicking biomaterials (oncomaterials).
  • To explore the diagnostic and therapeutic potential of these oncomaterials.

Main Methods:

  • Review of current literature on pre-metastatic niche formation and function.
  • Analysis of engineered biomaterials designed to mimic the niche microenvironment.
  • Discussion of how these biomaterials can be used to study and manipulate tumor cell behavior.

Main Results:

  • Engineered niche-mimicking biomaterials can regulate tumor cell behavior at implant sites.
  • These oncomaterials show potential for early detection of metastatic events.
  • Oncomaterials offer strategies for inhibiting pre-metastatic niche formation and attenuating metastatic progression.

Conclusions:

  • Engineered oncomaterials represent a promising strategy for addressing challenges in cancer metastasis.
  • These biomaterials have significant potential for both early cancer detection and therapeutic intervention.
  • Further development of oncomaterials could lead to novel approaches to inhibit metastatic spread.
