Tissue culture is the growth of tissues or cells in an artificial medium separate from the parent organism. This fast dividing replacement tissue called callus can be induced in various in vitro-cultured explants by external ad-dition of plant growth regulators (PGRs). tracheal ring culture is done for isolation of coronavirus. Using the appropriate growing conditions for each explant type, plants can be induced to rapidly produce new shoots, and, with the addition of suitable hormones new roots. •Variation in micropropagated plants 6. Organ cultures are mainly done for highly specialized parasites of certain organs e.g. The parts of an organ or a whole organ can be cultured in vitro. Explants of human tumour tissue grown in vitro can be tested for chemosensitivity in order to tailor the patients chemotherapy to suit the individual … •Developmental stages in micropropagation 4. This technique is also called micropropagation.This is typically facilitated via use of a liquid, semi-solid, or solid growth medium, such as broth or agar.Tissue culture commonly refers to the culture of animal cells and tissues, with the more specific term plant tissue culture being used for plants.

Tissue culture produces clones, in which all product cells have the same genotype (unless affected by mutation during culture). Several cell culture procedures have been developed in the current century which overcome the drawbacks of traditional culture procedures and are more scientifically rigorous, such as stem cell derived human cells, co-cultures of different cell types, scaffolds and extracellular matrices, tissue architecture, perfusion platforms, organ-on-chip technologies, 3D culture and organ functionality. Anther Culture. The organ used may be embryo, seed, root, endosperm, anther, ovary, ovule, meristem … Choosing a medium for different cell types ... Cytotoxicity testing : Tissue culture has been used to screen many anti-cancer drugs since the demonstration in 1950 of clear correlation between invitro and invivo activities of potential chemotherapeutic agents.
