Researchers have long debated whether new pancreatic β cells derive from stem cells or from pre-existing β cells. A new study in this issue of Cell Stem Cell (Smukler et al., 2011) suggests that both sides may be right.
研究人员长期以来一直在争论新的胰腺β细胞是来自于干细胞还是来自于先前存在的β细胞。本期《细胞干细胞》杂志上的一项新研究（Smukler 等人，2011）表明，双方可能都是对的。
