  • Analysis of studies investigating various tissues and organs.
  • Examination of applications in descriptive, cell differentiation, and ontogenetic studies.

Main Results:

  • Lectins are crucial histochemical tools due to their specific carbohydrate binding.
  • Various labels (fluorochromes, enzymes, gold) enable visualization across microscopy types.
  • Studies have focused on rodent and human tissues, with potential for comparative vertebrate research.

Conclusions:

  • Lectin histochemistry is a versatile technique for biological research.
  • Its specificity and preservation of tissue integrity are key advantages.
  • The growing number of publications indicates significant promise in pathology.
