Study Notes
Vital Staining
- Vital staining depends on the vitality of the cell or organoid
- Stained cells are stainable when they are living
- This technique is divided into two parts:
- Intravital staining: means staining of living cells inside the living body.
- Example: staining of macrophages by Indian ink
- Supra vital staining: means staining of living cells or organoids outside the body.
- Example: staining of mitochondria by Janus green B and reticulocytes with brilliant crezyl blue.
- Intravital staining: means staining of living cells inside the living body.
Tissue Culture
- Living cells and tissues can be maintained and studied outside the body in culture (in vitro)
- Cells and tissues are grown in complex solutions containing salts, amino acids, and vitamins.
Importance of Tissue Culture
- To study chromosomes of cells in various diseases
- For research purposes such as studying the effect of certain drugs on the cells.
