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

而另一种混合物则促使干细分化为成牙细。

They also assessed another type of cell called odontoblasts.

他们还评估了另一种被称为成牙细细。

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

一些变成成牙质细——这些细形成牙质，坚硬纤维牙质，牙齿核心部分。

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

成牙本质细则需要更复杂，但与成釉细不同，它们不会消失，会在我们有生之年继续分泌牙本质。

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

在形成牙齿时，成牙本质细向牙内部扩散，成釉细则向牙外部生长，并在抵达牙齿表面时脱落。

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

分泌牙釉成釉细以及分泌牙本质成牙本质细。

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.

牙髓外层有成牙质细，它们可以分泌一种叫牙本质骨样组织，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.

成牙质细有长长突起，或者说长臂，伸入牙本质中小管，就像章鱼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.

拥有这两种细类型似乎至关重要: 当成牙釉质细和成釉细同时存在时，编码牙釉质蛋白基因比单独存在成釉细时表达得更强烈。
