Cell counting is any of various methods for the counting or similar quantification of cells in the life sciences, including medical diagnosis and treatment. It is an important subset of cytometry , with applications in research and clinical practice.
Counting cells is an important aspect of cytometry used widely in research and clinical medicine. It is generally achieved by using a manual or digital cytometer to count the number of cells present in small fractions of a sample, and then extrapolating to estimate the total number present in the entire sample. The resulting quantification is ...
Cytometers are the instruments which count the blood cells in the common blood test.. Cytometry is the measurement of number and characteristics of cells.Variables that can be measured by cytometric methods include cell size, cell count, cell morphology (shape and structure), cell cycle phase, DNA content, and the existence or absence of specific proteins on the cell surface or in the ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
It is often important to record the approximate number of divisions cells have had in culture by recording the number of passages or subcultures. In the case of plant tissue cells, somaclonal variation may arise over long periods in culture. Similarly in mammalian cell lines, chromosomal aberrations have a tendency to increase over time. For ...
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
