How does tissue culture differ from cell culture?

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 the context of biology, the terms "tissue culture" and "cell culture" are closely related and often used interchangeably in a broad sense. Both refer to the maintenance and growth of biological materials—such as cells, tissues, or organs—outside of an organism in a controlled, sterile laboratory environment.1

However, there is a technical distinction in their scope:

Tissue culture is a broad method of biological research where fragments of tissue from an animal or plant are transferred to an artificial environment to survive and function. This process can involve culturing a single cell, a population of cells, or even a whole or part of an organ.2
Cell culture specifically refers to the maintenance and growth of cells isolated from multicellular organisms.1

In practice, when researchers initiate a culture, they often disperse a tiny sample of tissue into a medium. Because the objects of tissue culture—whether they are individual cells or complex tissue fragments—are maintained under precise conditions of nutrition, temperature, and humidity, the techniques used for both are fundamentally integrated.21
