tissue culture Tissue culture often requires sterile working conditions and thus is typically performed in a laminar flow cabinet (or tissue culture hood), which circulates filtered air to reduce the risk of culture contamination.

In tissue culture, cells are grown on glass or plastic surfaces by placing them in a sterile, controlled environment that provides the necessary nutrients, temperature, and humidity for survival and reproduction.12

When these cells are introduced to a culture dish, they adhere to the surface and begin to divide. As they proliferate, they spread across the bottom of the container until they form a single, densely packed layer. This process is governed by the cells' interaction with their environment; specifically, molecules associated with the cell membrane act as receptors that link the cells to the surface or to the extracellular matrix, which can be present on the culture substrate.23

Growth continues until the cells become so crowded that they are in constant contact with one another. At this point, a phenomenon known as contact inhibition of growth occurs, where the physical proximity of neighboring cells provides a signal that slows or stops further cell division.2
