Tissue culture is the general name for the removal of cells, tissues or organs from an animal or plant and their subsequent placement into artificial environment conductive to growth. This environment usually consists of a suitable glass or plastic culture vessel containing a liquid or semi-solid support medium that supplies the nutrients essential for survival and growth. Chapters 12, 13, 16, 17. Limits to Cell Growth. The larger a cell becomes, the more demands a cell places on its DNA. If extra copies of DNA are not made, an “information crisis” would occur. The cell also has more trouble moving nutrients and wastes across the cell membrane. Van Delden C, Iglewski BH. Cell-to-Cell Signaling and Pseudomonas aeruginosa Infections.
