A different cocktail pushed the stem cells to become odontoblasts instead.

而另一种混合物则促使干胞分化为胞。

They also assessed another type of cell called odontoblasts.

他们还评估了另一种被称为胞的胞。

Some become odontoblasts — these cells make dentin, the tough, fibrous core of the tooth.

一些变质胞——这些胞形质，坚硬的纤维质，齿的核心部分。

Odontoblasts use a more complex process, but unlike ameloblasts, they stick around, continuing to secrete dentin throughout your life.

质胞则需要更复杂的过程，但与釉胞不同，它们不会消失，会在我们有生之年继续分质。

As they form teeth, odontoblasts move inward, while ameloblasts move out and slough off when they hit the surface.

在形齿时，质胞向内部扩散，釉胞则向的外部生长，并在抵达齿表面时脱落。

This amazing structure is created by two types of cells: ameloblasts that secrete enamel and odontoblasts that secrete dentin.

分釉的釉胞以及分质的质胞。

The outer wall of the pulp, contains odontoblasts which are cells that secrete a bonelike substance called dentin, which is filled with protein and minerals.

髓外层有质胞，它们可以分一种叫质的骨样组织，其中充满了蛋白质和矿物质。

The odontoblasts have long processes, or arms, that lay within tiny tubules in the dentin - like an octopus sticking it's arms through a block of cement.

质胞有长长的突起，或者说长臂，伸入质中的小管，就像章鱼的触角伸进水泥块被困住一样。

Having both cell types seemed to be crucial: when odontoblasts were present alongside ameloblasts, genes coding for enamel proteins were more strongly expressed than with ameloblasts alone.

拥有这两种胞类型似乎至关重要的: 当釉质胞和釉胞同时存在时，编码釉质蛋白的基因比单独存在釉胞时表达得更强烈。
