Tissue culture commonly refers to the culture of animal cells and tissues, with the more specific term plant tissue culture being used for plants. The lifespan of most cells is genetically determined, but some cell-culturing cells have been 'transformed' into immortal cells which will reproduce indefinitely if the optimal conditions are provided.
A cell line can be defined as a permanently established cell culture which will propagate forever. Investigators mostly get cell lines from other investigators or from cell banks (such as the American Type Culture Collection) , because its much easier than creating new one. In special cases, investigators are obligated to establish a cell line.
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
Cell culture in a special tissue culture dish. Cell culture can be an alternative to animal use in some cases. For example, cultured cells have been developed to create monoclonal antibodies; prior to this, production required animals to undergo a procedure likely to cause pain and distress. [7]
Wilton Robinson Earle (June 22, 1902 – May 30, 1964) was an American cell biologist known for his research in cell culture techniques and carcinogenesis.Born in Greenville, South Carolina, he earned a bachelor's degree at Furman University then earned an M.A. at the University of North Carolina and PhD at Vanderbilt University in 1928.
He coined the term cell (from Latin cellula, meaning "small room" [41]) in his book Micrographia (1665). [42] [40] 1839: Theodor Schwann [43] and Matthias Jakob Schleiden elucidated the principle that plants and animals are made of cells, concluding that cells are a common unit of structure and development, and thus founding the cell theory.
Dilution cloning or cloning by limiting dilution [1] [2] describes a procedure to obtain a monoclonal cell population starting from a polyclonal mass of cells. This is achieved by setting up a series of increasing dilutions of the parent (polyclonal) cell culture. A suspension of the parent cells is made. Appropriate dilutions are then made ...
Evidence for animal culture is often based on studies of feeding behaviors, [8] vocalizations, [4] predator avoidance, [9] mate selection, [10] and migratory routes. [11] An important area of study for animal culture is vocal learning, the ability to make new sounds through imitation. [4] Most species cannot learn to imitate sounds.
