• 成年鼠视网膜干细胞的研究进展

    摘要:以往研究认为,脊椎动物的睫状边缘区是其视网膜细胞终生更新的来源,而成年哺乳动物视网膜没有再生能力.近年研究发现,在成年鼠的色素睫状上皮有一些细胞被生长因子刺激后可以增殖并分化为视网膜神经元及胶质细胞。本文对这类干细胞的位置、体内外的研究及其用途作一综述。 论文链接:

  • The criteria that a man chooses a woman

    一天,我在纽约一家饭馆吃饭。我右面餐桌旁有对夫妇在低声交谈,左面餐桌旁有3个青年在谈论篮球。我边吃边看报。 忽然,右边那对夫妇争吵起来。那男的轻声说了句什么,女的立即恼怒起来。“你一点不理解我!”她生气地说。接着她霍地站起,扯下餐巾扔到桌上,大步走了。那男的十分尴尬,朝我耸
