You might be old enough to remember the famous “Where’s the Beef?<\/a>” Wendy’s commercials. This question may be asked in a different context since\u00a0U.S. regulators approved<\/a>\u00a0the sale of lab-grown chicken meat made from cultivated cells in June 2023.<\/p>\n\n\n\n

Growing animal\u00a0cells<\/a>\u00a0in the lab isn’t new. Scientists have been culturing\u00a0animal cells<\/a>\u00a0in artificial environments\u00a0since the 1950s<\/a>, initially focusing on studying developmental biology and cancer. This technique remains one of the major tools in life science research, especially for\u00a0drug development<\/a>.<\/p>\n\n\n\n

What are cell cultures?<\/h2>\n\n\n\n

Cell cultures are typically grown using either natural or artificial growth media<\/a>. Natural media comprise naturally-derived biological fluids, whereas artificial media comprise both organic and inorganic nutrients and compounds. Both contain the necessary ingredients to foster the growth and development of cells. These ingredients typically contain nutrients such as vitamins, carbohydrates, amino acids<\/a> and other molecules that provide the fuel for cells to grow and multiply.<\/p>\n\n\n\n

Researchers use cells grown using\u00a0tissue culture<\/a>\u00a0to answer a\u00a0variety of experimental questions<\/a>.\u00a0As a biochemist<\/a>, I use plant tissue culture techniques in my courses and research program. Researchers can add viruses, bacteria, fungi, hormones, vitamins and other pathogens or compounds to cells grown in culture to observe how different factors affect the cells’ behavior or function, especially as it relates to which genes are turned on or off in the cell and which proteins respond to those pathogens or compounds.<\/p>\n\n\n\n
