Viability PCR workflow. Viability PCR, also named v-PCR or vPCR, is an evolution of PCR.Through the use of a simple pre-treatment of the sample by the means of specific intercalating photo-reactive reagents it's possible to neutralize the DNA of dead cells.
The morphometric method is a way to demonstrate cell death in the laboratory. Morphometric measurement provides the result of cell death as a volume, size, weight and length of tissue, organ and the whole organism that compares with before and after the occurrence of cell death. [2]
DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other contaminants, and purifying the DNA so that it is free of other cellular components.
Cell isolation is the process of separating individual living cells from a solid block of tissue or cell suspension. While some types of cell naturally exist in a separated form (for example blood cells ), other cell types that are found in solid tissue require specific techniques to separate them into individual cells.
Micrograph showing contraction band necrosis, a histopathologic finding of myocardial infarction (heart attack).. Histopathology (compound of three Greek words: ἱστός histos 'tissue', πάθος pathos 'suffering', and -λογία-logia 'study of') is the microscopic examination of tissue in order to study the manifestations of disease.
Protease viability marker: One can look at protease function in specimens if they wish to target viability in cells; this practice in research is known as "Protease Viability Marker Assay Concept". The actions of protease cease once a cell dies, so a clear-cut line is drawn in determining cell viability when using this technique. [5]
A cell that has accumulated a large amount of DNA damage or can no longer effectively repair its DNA may enter one of three possible states: an irreversible state of dormancy, known as senescence; cell suicide, also known as apoptosis or programmed cell death; unregulated cell division, which can lead to the formation of a tumor that is cancerous
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
