Biological cultures are a common laboratory means in order to study living organisms. There are different types of biological cultures, such as cell culture, tissue culture, and organ culture. Cell culture is a biological culture of cells of multicellular eukaryotes. Tissue culture is the cultivation of tissues from multicellular organisms. Organ culture is the cultivation of a part or all of an animal organ in a sterile controlled medium.
Organ culture is the cultivation of a part or the entire organ in the laboratory in such a way as to maintain some normal spatial relationships between cells and some normal function. It is different from cell culture where single cells are cultivated. It is also different from tissue culture although it develops from tissue culture methods.
Organ culture may involve a part of an organ or of the entire organ. What is essential is that the architecture of the tissue of the organ is preserved and to direct it towards development. Proper handling is essential so that the tissue would not be damaged and disrupted. Currently, the methods used in organ culture are Plasma clot method, Agar gel method, Raft Methods, and Grid Method.
