A stem cell line is a family of constantly dividing cells, the product of a single group of stem cells. They are obtained from human or animal tissues and can replicate for long periods of time in vitro ("within glass"; or, commonly, "in the lab", in an artificial environment). They are frequently used for research relating to embryonic stem cells or cloning entire organisms.

With no suspicion in stem end or blossom end
Of vitriol or arsenate of lead,
And so not good for anything but cider.”
