Animal cell culture is a laboratory technique that involves growing animal cells in a controlled environment outside their natural habitat. This process allows scientists to study cell behavior, test drugs, and produce biological products. Cells are typically grown in a nutrient-rich medium that provides essential nutrients and growth factors. The culture can be performed using various types of containers, such as Petri dishes or flasks, and requires specific conditions like temperature and humidity. Maintaining sterile conditions is crucial to prevent contamination. Overall, animal cell culture is a vital tool in fields like biotechnology, pharmaceutical research, and cell biology.
