what is Tissue Culture Lab
A tissue culture laboratory is a specialized bioscience facility designed for maintaining and manipulating living cells under controlled in vitro conditions. These sterile environments enable researchers to grow cells extracted from plants, animals, or humans in artificial media while preventing microbial contamination.The primary objectives of tissue culture labs are threefold:
- To preserve cell viability through precise environmental control.
- To facilitate genetic manipulation and experimental treatments.
- To enable large-scale production of biological materials for research and industrial applications. These facilities serve as critical infrastructure for advancements in fields ranging from cancer research to agricultural biotechnology.
