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 1907, American zoologist Ross G. Harrison achieved the first successful animal-tissue culture by demonstrating the growth of frog nerve cell processes in a medium of clotted lymph.12
This experiment was a significant breakthrough for several reasons:
- Settled Scientific Controversy: By observing that nerve-cell outgrowths displayed protoplasmic movement, Harrison resolved a long-standing debate regarding the formation and nature of nerve fibers.1
- Foundation of Modern Neurology: His observations provided the essential basis for modern nerve physiology and neurology.1
- Pioneered Tissue Culture: Harrisonās work established the first successful method for cultivating animal tissue outside of the body. This technique became a vital tool in biological research, eventually enabling critical advancements such as cancer research and the development of polio vaccines.12
By proving that cells could survive and function in an artificial environment, Harrisonās work paved the way for the broad field of tissue culture, which remains fundamental to understanding cell biology, genetics, and medicine today.2
