They tried hundreds of different recipes; eventually they discovered that if they mixed liver precursor cells (derived from iPS cells) with two other types of standard human cell lines known to be important for embryonic liver development, then the cells would spontaneously form a 4 to 5 - millimeter 3D structure called a liver bud.
