That also happens through development, and in fact, it goes through development and even teenagers are not fully myelinated.

髓鞘的形成也同样发生在发展过程之中,实际上,髓鞘的形成贯穿整个发展过程,即便是青少年的髓鞘也并未完全发育完善

For example, if I isolated this one called the myeloid cell, it's capable of forming red blood cells, megakaryocytes and neutrophils.

比如,如果我分离出一个髓系细胞,它就能生成红细胞,巨核细胞和嗜中性粒细胞

Finally, remember myelination, where you sort of get this fatty sheath over your neuron to make it more effective?

最后,回想一下髓鞘的形成,你会在哪里长出脂肪鞘,去包裹神经元,使得神经元更有效率

Pluripotent stem cells that are capable of self-renewal to generate themselves and are capable of dividing into both bioloid and lymphoid progenitor cells.

多能干细胞,是能够通过自我更新进行自我生成的细胞,也能分化成髓系祖细胞,或者淋巴祖细胞

耶鲁公开课 - 生物医学工程探索课程节选

This pluripotent stem cell is able to self-renew and it's able - generating committed progenitors of either the myeloid or the lymphoid lineage.

这种多能干细胞能自我更新,也可以生成定向祖细胞,可以是髓系祖细胞或者淋巴祖细胞

If this is the particular kind of axon that is 'myelinated', then it might have a layer of a special substance called myelin in sheathing the axon.

假设这是一种特殊的有髓鞘的轴突,它表面上会像鞘一样地包裹上一层,称为鞘磷脂的特殊物质

耶鲁公开课 - 生物医学工程探索课程节选

Surrounding the axon is a myelin sheath, which is actually just insulation.

髓鞘将轴突包裹起来,实际上形成了一个绝缘层

So it stimulates these myeloid cells to develop along this pathway.

它就是在髓细胞的发育过程中,发挥刺激生成作用的

In particular, they're not fully myelinated in their frontal lobes.

特别是他们额叶的髓鞘并未完全发育
