Other benign tumors are osteoblastomas and osteoid osteomas, both of which arise from osteoblasts.

其他良性肿瘤包括成骨细胞瘤、骨样骨瘤，两者均起源于成骨细胞。

These collagen fibers are the framework for the osteoblasts' work.

这些胶原纤维为成骨细胞的工作构建了框架。

Osteosarcomas arise from osteoblasts of different sizes - called pleomorphic - and these cells produce too much osteoid tissue.

骨肉瘤起源于大小不同的成骨细胞（多形性）；这些细胞会产生过多的类骨组织。

Now, for bones to grow and develop properly, special bone cells, called osteoblasts, are hard at work.

在骨正常的生长发育过程中，有一种特殊的骨细胞，成骨细胞，起了至关重要的作用。

Osteoclasts break down the unneeded mineral lattice using acids and enzymes so that osteoblasts can then add more material.

破骨细胞以酸和酵素酶 将无用的矿物晶格拆解这样就可以提供 更多原料给造骨细胞。

To build bone, osteoblasts secrete osteoid, which is an organic matrix made of type 1 collagen.

在构建骨的过程中，成骨细胞分泌类骨质，它是一种由1型胶原组成的有机质。

So an osteoblast in your bone becomes an osteocyte — ditto for chondroblasts becoming chondrocytes.

所以你骨骼中的成骨细胞就变成了一个骨细胞。——软骨母细胞成为软骨细胞也是如此。

Osteoblasts then deposit calcium and phosphate crystals into the framework.

之后成骨细胞会往这个框架内积聚钙和磷酸盐结晶。

This means that osteoblasts don't have enough calcium and phosphate to deposit into the organic matrix.

这意味着成骨细胞没有足够的钙和磷可以沉积到骨有机质中。

But before they auto-terminate, they use the hormone hotline to call over the osteoblasts, who come in and begin rebuilding the bone.

但是在它们自动终止之前，它们使用激素热线呼叫成骨细胞，成骨细胞进来开始重建骨骼。
