Organ Cultures on Agar - Media solidified with agar are also used for organ culture and these media consist of 7 parts 1 % agar in BSS, 3 parts chick embryo extract and 3 parts horse serum. In some other studies, defined media with or without serum are used with agar

The medium with agar has the advantage that the support for organ culture does not liquefy and no additional mechanical support is required. Embryonic organs generally grow well on this medium, but tumours from adults will not survive.
