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.

Tissue culture allows researchers to study changes in gene or protein expression by subjecting cultured cells to a wide range of experimental treatments, such as the addition of hormones, drugs, viruses, or potential cancer-causing chemicals.1

By introducing these agents to the culture medium, scientists can observe the cells to detect specific molecular alterations, including changes in the expression of a particular gene or protein. These techniques enable researchers to investigate the biochemical and genetic activity of cells, helping to clarify the genetic causes of hereditary diseases, identify chromosomal abnormalities, and understand how various physical, chemical, or biological agents influence cellular function.1
