Using blood to nourish and grow the stem cells, Zhu managed to induce them to differentiate into three lineages: first bone and cartilage, then muscle, and then neuron.

利用血液去培育干细胞获得成功以后，朱敏设法诱导它们分化成三种细胞系：先是骨骼和软骨细胞，然后是肌细胞，再是神经元。

In front, the long thin cellular protrusion of the neuron extends, pauses, then drags the bulbous cell body behind it, then extends again, and so on.

前端，又细又长的神经元伸展的细胞突出停止，然后拖动后边的球状细胞，然后再次伸展，如此反复。

And then if you get a certain number, plus 60 or something, the neuron will fire and it fires along the axon, the thing to the right.

如果达到了一定的数量，比如超过60之类的，神经元便会产生神经冲动，神经冲动沿轴突传递，右边的是轴突。
