What is Flow cytometry?
Cell Cytometry is a technique used to detect and measure physical and chemical characteristics of cells. It allows scientists to obtain quantitative measurements on parameters such as cell size, cell count, and fluorescence—the amount of light emitted by a fluorescent dye that is bound to molecules within cells. These characteristics provide information on certain cell populations and activities. Cells from blood, bone marrow, tumor tissues, and other sources can be analyzed using flow cytometry instruments.
Flow Cytometry Technique
One of the most common flow cytometry techniques is flow cytometry. In this technique, cells pass in a fluid stream through a laser beam. As each cell passes through the laser, it scatters the light and may also emit light depending on the dyes used. Detectors then collect information on the cells, with parameters like light scatter properties and fluorescence intensities being measured electronically on a cell-by-cell basis and analyzed by computer software. This allows identification, enumeration, and characterization of different cell populations in a complex sample based on their molecular and physical properties.
Uses of Cell Cytometry
Flow cytometry has numerous uses in research, clinical, and industrial settings. In research, it is commonly used for cell sorting, immunophenotyping, cell cycle analysis, and detection of fluorescent markers and reporters in cells and organisms. Clinically, flow cytometry is widely used for immunophenotyping in hematology and leukemia diagnosis. It also has applications in transplant monitoring and stem cell research. Beyond these, flow cytometry finds use in detecting bacterial or viral particles, screening and sorting sperm and stem cells, and measuring protein expression in cells. Flow cytometry has become an indispensable tool for research in areas like immunology, cancer biology, and more due to its ability to provide multiparameter data at the single-cell level.
Multicolor Flow Cytometry
Modern flow cytometers are capable of detecting a combination of up to 14 fluorescent dyes simultaneously on a cell-by-cell basis. This allows techniques like multicolor flow cytometry. Here, cells are stained with two or more fluorescent antibodies or other labels, with each label emitting at a different wavelength. The cytometer can distinguish the different dyes based on their fluorescent colors and deduce the presence of multiple molecules per cell. This gives insight into cell populations and states defined by co-expression of markers.
Multicolor flow has enabled more detailed analysis of cell phenotypes and better resolution of rare cell populations. It is especially important for immunophenotyping where expression of combinations of cell surface markers distinguishes cell types. Advanced cell sorting capabilities allow isolation of specific cell subpopulations for further analysis based on their multicolor profiles. Multicolor flow cytometry has emerged as a powerful tool in fields such as immunology, stem cell research, and cancer biology.
Mass Cytometry Technique
While conventional flow cytometers use fluorescent probes, Cell Cytometry employs metal-labeled antibodies and utilizes mass spectrometry for detection. In mass cytometry or CyTOF, cell markers are tagged with heavy metal isotopes instead of fluorophores. When cells marked with these antibodies are run through the instrument, they are vaporized, ionized, and accelerated. Their mass-to-charge ratios are then detected using time-of-flight mass spectrometry, allowing identification of the metal tags and the corresponding markers on each cell.
Mass cytometry overcomes limitations of fluorescence-based techniques like spectral overlap and limits on the number of parameters measured simultaneously. It is capable of measuring over 50 parameters in single cells. This expanded dimensionality yields more comprehensive analysis of cell phenotypes and states. Some applications of mass cytometry include identifying rare cell types, characterizing the composition of tissues, tracking cellular responses to drugs or other stimuli, and more. The non-overlapping mass signals are also less prone to spillover, raising its accuracy in detecting multiple protein expression profiles. However, mass cytometry is still lower throughput compared to traditional flow cytometry.
Imaging Cell Cytometry
More recently, imaging flow cytometry instruments have emerged that combine elements of flow cytometry and fluorescence microscopy. In imaging flow cytometry, digital images are captured for each cell as it passes through the instrument. This allows morphological as well as intracellular parameters to be measured in single cells. Cells are imaged using either brightfield or fluorescence microscopy at high resolution and speed. Software then analyzes the images automatically to extract features such as shape, size, texture, expression levels across different areas in a cell.
An advantage of imaging flow cytometry is it provides both quantitative data from many cells like conventional flow, along with high resolution images of each analyzed cell. This enables correlation of morphological features and subcellular localization of markers within single cells. Some applications include detection of rare cell populations, cell cycle analysis, studying intracellular localization of proteins, screening samples for abnormal cell morphologies, and more. Imaging flow cytometry facilitates more detailed analysis compared to standard flow while maintaining its high throughput analytical power.
In summary, Cell Cytometry techniques such as flow cytometry and its variants have enabled quantifiable, multiparameter analysis of single cells at a scale not possible with older methods. They continue to find widespread use through constant improvements in sensitivity, resolution, and number of parameters measured. Flow cytometry has emerged as an indispensable tool in clinical diagnostics, biological research, and industrial applications by providing comprehensive insight into cells and cell populations.
