Flow Cytometry01:23

Flow Cytometry

The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

Immunocytochemistry and Immunohistochemistry01:22

Immunocytochemistry and Immunohistochemistry

Immunocytochemistry (ICC) and immunohistochemistry (IHC) are techniques that use antibodies to check for specific proteins or antigens in a sample. The technique was first published by Albert Coons in 1941 to detect the presence of pneumococcal antigen in tissue sections from mice infected with Pneumococcus. Immunocytochemistry helps localization of proteins or antigens in individual cells like blood cells, stem cells, etc., while immunohistochemistry does the same for tissue samples.

Summary

Cytochemistry aids in diagnosing leukemias by detecting enzymes and substances like glycogen in developing blood cells. Despite advanced techniques, these studies remain crucial for evaluating abnormal blood and bone marrow smears.

Area of Science:

  • Hematology
  • Cell Biology
  • Biochemistry

Background:

  • Hematopoiesis involves the production of enzymes and substances like glycogen in developing cells.
  • These cellular components can serve as indicators for leukemia lineage and classification.
  • While advanced methods exist, cytochemistry retains significance in hematological diagnostics.

Purpose of the Study:

  • To highlight the continued importance of cytochemical studies in evaluating leukemias.
  • To emphasize the role of cytochemistry alongside modern diagnostic techniques.

Main Methods:

  • Cytochemical staining of blood and bone marrow smears.
  • Detection of enzymes and substances such as glycogen within hematopoietic precursors.

Main Results:

  • Specific enzymes and glycogen presence in developing cells offer clues to leukemia classification.
  • Cytochemical findings correlate with abnormal white blood cell populations.

Conclusions:

  • Cytochemistry remains a valuable tool in the assessment of leukemias and other hematological disorders.
  • It complements immunohistochemistry, flow cytometry, and molecular studies in diagnosing blood diseases.
