One of the primary advantages of cell culture is the ability to isolate a single type of cell from a multicellular organism. How has this advance changed the study of biology?

Isolating one cell type removes the influence of other cell types, so scientists can attribute a response in the culture to the cells being studied. This helps researchers investigate how that particular cell type responds to conditions or treatments. It does not eliminate all animal or human testing, guarantee that cells behave exactly as they do in an organ, or mean single-cell-type cultures are always easier or cheaper to maintain.
