神经学家认为,脑内单纯的结构支架细胞有可能成为未来治疗退化性脑疾病的关键。瑞典科学家证明,室管膜细胞不仅能把脑周围和脊髓周围的液体从神经组织中分离出来,而且它们能做更多事情。实际上,它们可能含有脑储备的干细胞。干细胞继续发育成为成熟的细胞,脑内的这些细胞包括神经元和各种称作神经蚀质细胞的支架细胞。长期以来一直认为只有脑胚胎具有干细胞,这意味着与骨或血不同,成人脑不能再生。但是近几年,科学家们证明

Neuroscientists believe that simple structural scaffold cells in the brain may become the key to treating degenerative brain diseases in the future. Swedish scientists have shown that ependymal cells can not only separate fluid around and around the spinal cord from nerve tissue, but they can do more. In fact, they may contain brain-reserve stem cells. Stem cells continue to develop into mature cells, and these cells in the brain include neurons and a variety of scaffold cells called neuroepithelial cells. It has long been believed that only brain embryos have stem cells, which means that, unlike bones or blood, adult brain can not regenerate. But in recent years, scientists have proved
