The field of biomaterials continues to advance the introduction of such complexity into cell culture systems, providing ways to control mechanical, compositional, and structural cues and thus more accurately represent features of native tissues 2.A range of biomaterial systems have been developed towards this goal, for example patterned glass substrates, elastomeric films, hydroxyapatite. The stage of the culture after isolation of the cells but prior to the first sub culture after which it becomes a cell line is termed as primary culture. It refers to that stage of the culture after the isolation of cells from tissue, where the cells are proliferated under appropriate conditions until they occupy all of the available substrate The most important and crucial step in cell culture is selecting appropriate growth medium for the in vitro cultivation. A growth medium or culture medium is a liquid or gel designed to support the growth of microorganisms, cells, or small plants. Cell culture media generally comprise an appropriate source of energy and compounds which regulate.

Hopes of growing poliovirus in the lab without the use of live animals drove many of the researchers in the 1930s and 1940s. Cell cultures involve growing cells in a culture dish, often with a supportive growth medium like collagen. They offer a level of control that was unavailable using live. Further cell migration is then inhibited, and normal cells adhere to each other, forming an orderly array of cells on the culture dish surface. Tumor cells, in contrast, continue moving after contact with their neighbors, migrating over adjacent cells, and growing in disordered, multilayered patterns NOTE: If cells are to be put in culture, perform all steps using asceptic techniques. 1.
