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

而另一种混合物则促使干细胞分化为成细胞。

2.They also assessed another type of cell called odontoblasts.

他们还评估了另一种被称为成细胞的细胞。

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

一些变成成质细胞——这些细胞形成质，坚硬的纤维质，的核心部分。

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

在形成时，成本质细胞向内部扩散，成釉细胞则向的外部生长，并在抵表面时脱落。

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

分泌釉的成釉细胞以及分泌本质的成本质细胞。

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

成本质细胞则需要更复杂的过程，但与成釉细胞不同，它们不会消失，会在我们有生之年继续分泌本质。

7.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.

髓外层有成质细胞，它们可以分泌一种叫本质的骨样组织，其中充满了蛋白质和矿物质。

8.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.

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

9.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.

拥有这两种细胞类型似乎至关重要的: 当成釉质细胞和成釉细胞同时存在时，编码釉质蛋白的基因比单独存在成釉细胞时表得更强烈。
