“微型大脑”英、德等国研究人员用人类多功能干细胞在试管中培育出一个模拟人脑的组织,希望借助这种“微型大脑”促进神经科学和人脑早期发育等方面的研究。研究人员先用干细胞培育出脑细胞,并让这些脑细胞逐渐形成脑组织,与真实大脑一样成层状分布,其结构、功能都与人类大脑早期发育时的形成十分类似。虽然这种“微型大脑”直径仅有4毫米左右,但研究人员认为它有很高的科研价值,比如探寻神经系统疾病在大脑早期发 Researchers in Britain, Germany and other countries use human pluripotent stem cells to develop a tissue that mimics the human brain in the test tube, hoping to promote neuroscience and early development of the human brain with this “miniature brain” Research. Researchers first use stem cells to cultivate brain cells, and let these brain cells gradually formed brain tissue, layered with the same as the real brain, its structure and function are very similar to the formation of human brain early development. Although this “miniature brain” has a diameter of only about 4 millimeters, researchers think it has high scientific value, such as exploring neurological diseases early in the brain
