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

其他良性括成骨细胞、骨样骨，两者均起源于成骨细胞。

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

所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。

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。

Osteoblasts then deposit calcium and phosphate crystals into the framework.

之成骨细胞会往这个框架内积聚钙和磷酸盐结晶。

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。

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。

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

破骨细胞酸和酵素酶 将无用的矿物晶格拆解这样就供 更多原料给造骨细胞。

Bone mineralization is dependent on an enzyme called alkaline phosphatase - which increases in response to osteoblast activity.

骨的矿化依赖碱性磷酸酶；碱性磷酸酶响应成骨细胞活性而增加。

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。

Hydrochlorothiazide boosts calcium retention in the kidney and directly stimulates osteoblast differentiation, therefore decreasing mineral bone loss.

氢氯噻嗪促进肾脏中钙的保留且直接刺激造骨细胞分化，因此减少骨质流失。

They're like the construction foremen of your bones, passing along commands to your skeleton's two main workhorses: the osteoblasts and the osteoclasts.

它们就像你骨骼的建筑工头，将命令传递给你骨骼的两个主要主力：成骨细胞和破骨细胞。

Eventually osteoblasts get activated and a process called ossification will start, which is when the fibrous tissue turns to bone.

最成骨细胞活化，骨化过程启动，纤维组织最终转化为骨组织。

Likewise, osteoblasts are the blast cells of bone tissue, and the matrix they lay down is the nexus of calcium carbonate that forms your bone.

同样地，成骨细胞是骨组织的成骨细胞，它们形成的基质是形成骨骼的碳酸钙的结合体。

When osteoblasts come in, they secrete a glue-like cocktail of collagen, as well as enzymes that absorb calcium, phosphate, and other minerals from the blood.

当成骨细胞进入时，它们分泌胶原蛋白及从血液中吸收钙、磷酸盐和其他矿物质的酶。

And finally we got an introduction to the process of bone remodeling, which is carried out by crews of osteocytes, osteoblasts, and osteoclasts.

最，我们得到了骨骼重塑过程的介绍，这是由骨细胞、成骨细胞和破骨细胞团队进行的。

Now, even though parathyroid hormone stimulates bone resorption, it's been found that intermittent injections with teriparatide activates osteoblasts more than osteoclasts, therefore increasing bone formation.

其实，即使甲状旁腺激素刺激骨吸收，研究发现间歇性注射特立帕肽激活了更多造骨细胞而非破骨细胞，从而增强骨生长。

Ok, now, when osteoclasts break down bone faster than the osteoblasts can rebuild it, it results in the lowering of the bone mass and eventually in osteoporosis.

那么，当破骨细胞分解骨骼的速度比造骨细胞重建骨骼更快时，骨量就会减少，最终导致骨质疏松。

So while your osteoblasts are the bone-makers, your osteoclasts are the bone-breakers — which is a kind of violent image. Maybe think of them as like a bone-breaker-downer.

所当你的成骨细胞是骨骼制造者，你的破骨细胞是骨骼破坏者——这是一种暴力的形象。也许把它们想象成一个碎骨剂。
