Area of Science:

  • Biomedical Research
  • Pathology
  • Molecular Biology

Background:

  • In situ tissue observation is vital for biomedical research.
  • Common methods include histopathology, immunohistochemistry (IHC), immunofluorescence (IF), and in situ hybridization (ISH).

Purpose of the Study:

  • To introduce commonly used in situ methods: hematoxylin and eosin (H&E) staining and double IF staining.
  • To explain their applications in identifying breast lesion morphology and studying protein-protein interactions for signaling mechanisms.

Main Methods:

  • Hematoxylin and eosin (H&E) staining for general morphology.
  • Double immunofluorescence (IF) staining for protein-protein interactions.
  • Histopathology of breast lesions and molecular marker reclassification of breast cancers.

Main Results:

  • H&E staining effectively identifies different pathological types of breast lesions.
  • Double IF staining is valuable for investigating tissue-based protein interactions and signaling pathways.
  • Histopathology provides essential context for applying these techniques and reclassifying breast cancers.

Conclusions:

  • H&E and double IF staining are essential in situ techniques for breast lesion analysis.
  • Understanding histopathology and molecular markers aids in accurate diagnosis and classification.
  • These methods are fundamental for advancing biomedical scientific research in pathology and molecular biology.
