The cultivation of cells in the laboratory. Cell culture is the growth of living cells or microorganisms in a controlled artificial environment. Bacteria and yeasts may be grown suspended in a liquid medium or as colonies on a solid medium (usually solidified by 1.5–2.5% agar); molds grow on moist surfaces; and animal and plant cells (tissue cultures; Fig. 1) usually adhere to the glass or plastic beneath a liquid medium. Cell cultures must provide sources of energy and raw material for biosynthesis, as well as a suitable physical environment.
