out this side and goes back to the patient.

自这里流出回到病人体内
That urea is removed by the dialysate

这些尿素由流经空心纤维周围的
that goes around the hollow fibers.

透析液带走
Well, what if you changed this design slightly

如果你小小地改动一下这个设计
and asked it to do something different?

会发生什么变化呢
Instead of just flowing in a solution of saline

我们把流经空心纤维周围用来析出血中
or a balanced salt solution that was designed to pull urea out of the blood,

那些尿素的盐溶液或者平衡盐溶液
what if you put cells in the area around these hollows fibers?

用细胞来代替会发生什么
What if you put cells in?

如果用细胞代替会发生什么
What if they were cells from the pancreas, for example?

比如用胰腺细胞来代替会怎么样
Now, blood is flowing through this hollow fiber just like before.

血液还是像一起一样流经这些空心纤维
On the outside there's not just a solution of salt,

而外面不再是盐溶液
