It provides an in vitro model of the tissue in a well defined environment which can be easily manipulated and analysed.
Tissue culture is an important tool for the study of the biology of cells from multicellular organisms. On the other hand, the strict meaning of "tissue culture" refers to the culturing of tissue pieces, i.e.
Thus, in its broader sense, "tissue culture" is often used interchangeably with " cell culture". The cells are bathed in a culture medium, which contains essential nutrients and energy sources necessary for the cells' survival. These cells may be cells isolated from a donor organism ( primary cells) or an immortalised cell line. In modern usage, "tissue culture" generally refers to the growth of cells from a tissue from a multicellular organism in vitro. His original idea, presented in 1902, was called totipotentiality: “Theoretically all plant cells are able to give rise to a complete plant.” Modern usage Since Haberlandt's original assertions, methods for tissue and cell culture have been realized, leading to significant discoveries in biology and medicine. He suggested that the potentialities of individual cells via tissue culture as well as that the reciprocal influences of tissues on one another could be determined by this method. Gottlieb Haberlandt first pointed out the possibilities of the culture of isolated tissues, plant tissue culture. In 1996, the first use of regenerative tissue was used to replace a small length of urethra, which led to the understanding that the technique of obtaining samples of tissue, growing it outside the body without a scaffold, and reapplying it, can be used for only small distances of less than 1 cm. Lambert grew vaccinia virus in fragments of guinea pig corneal tissue. In 1907 the zoologist Ross Granville Harrison demonstrated the growth of frog embryonic cells that would give rise to nerve cells in a medium of clotted lymph. In 1885 Wilhelm Roux removed a section of the medullary plate of an embryonic chicken and maintained it in a warm saline solution for several days, establishing the basic principle of tissue culture.
