According to an announcement made on January 22, the researchers created the tiny figurine by cultivating 100,000 cell capsules -- 0.1-millimeter balls of collagen, each coated with dozens of skin cells -- together inside a doll-shaped mold for one day. After the cell capsules had coalesced to form the doll-shaped mass of tissue, it was placed in a culture solution, where it reportedly survived for more than a day.
