In biology, explant culture is a technique to organotypically culture cells from a piece or pieces of tissue or organ removed from a plant or animal. The term explant can be applied to samples obtained from any part of the organism. The extraction process is extensively sterilized, and the culture can be typically used for two to three weeks. [1]
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.
The removal of dead cells by neighboring phagocytic cells has been termed efferocytosis. [69] Dying cells that undergo the final stages of apoptosis display phagocytotic molecules, such as phosphatidylserine , on their cell surface. [ 70 ]
Cell culture is a fundamental component of tissue culture and tissue engineering, as it establishes the basics of growing and maintaining cells in vitro. The major application of human cell culture is in stem cell industry, where mesenchymal stem cells can be cultured and cryopreserved for future use. Tissue engineering potentially offers ...
The group recorded the final cell number as approximately 1.7 x 10 7 cells from a starter batch of only 200,000 cells. When the same group cultured human choriocarcinoma cells on polymeric and silicone polycarbonate capillary membranes totaling less than 3 cm 3 in volume, the cells expanded to an amount approximating 2.17 x 10 8 cells.
Phagocytes are crucial in fighting infections, as well as in maintaining healthy tissues by removing dead and dying cells that have reached the end of their lifespan. [ 10 ] During an infection, chemical signals attract phagocytes to places where the pathogen has invaded the body.

The measurement of cell death by using this dye is observing a change of color or the formation of fluorescence. When the cell died the nucleus went through destruction stages, one of them pyknosis, which lead to the release of a basic histone group and this happened when the irreversible condensation of chromatins occurred. The phagocytosis ...
