ABSTRACT
The arti cial culture of living tissues outside a living body is called the cell culture. Before cell culture, it has to be decided whether to take the cells from animal tissues or
from a culture collection. Direct isolation from the tissues is demanding and troublesome; however, it ensures that the cell culture will be in an environment closer to in vivo. On the other hand, establishing a culture from a cell sample is an easy and recommended route for obtaining cells that have been well characterized in terms of growth, origin, and genetic traits.
