The Tumor Microenvironment02:17

The Tumor Microenvironment

8.2K
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:

  • Biomedical Optics
  • Pathology
  • Microscopy

Background:

  • Polarized light imaging offers detailed microstructural insights.
  • Abnormal tissue detection benefits from advanced imaging techniques.

Purpose of the Study:

  • To develop and validate a Mueller matrix microscope for pathological tissue analysis.
  • To quantitatively assess microstructural features in cancerous tissues.

Main Methods:

  • Integrating a polarization state generator and analyzer (PSG and PSA) into a commercial transmission optical microscope.
  • Calibrating the system to minimize Mueller matrix element errors to 0.01.
  • Examining human cervical and liver cancerous tissues with fibrosis.

Main Results:

  • Transformed Mueller matrix parameters provided quantitative assessment of pathological tissue features.
  • Monte Carlo simulations using a sphere-cylinder birefringence model supported experimental findings.
  • Microscopic Mueller matrix parameters differentiated tissue changes in cervical and liver cancers.

Conclusions:

  • The Mueller matrix microscope accurately distinguishes microstructural differences in cancerous tissues.
  • The technology demonstrates potential for diagnosing cervical cancer by identifying birefringent tissue breakdown.
  • It also shows promise for liver cancer diagnosis by detecting birefringent structures associated with inflammation.
