Although neurogenesis continues throughout life in the mammalian brain, the issue of whether the stem cells that drive the process in vivo are self-renewing and multipotent remains unclear. In a recent landmark paper by Bonaguidi et al. (2011) published in Cell, the authors provide clonal evidence that neural stem cells in the dentate gyrus of the adult hippocampus are indeed multipotent and undergo symmetric cell divisions.
尽管神经发生在哺乳动物的大脑中持续一生,但驱动这一过程的干细胞是否具有自我更新和多能性仍不清楚。在最近发表在《细胞》杂志上的一篇具有里程碑意义的论文中,Bonaguidi 等人(2011 年)提供了克隆证据,证明成年海马齿状回中的神经干细胞确实具有多能性,并经历对称细胞分裂。
