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。

This receptor protein is particularly abundant on cells called osteocytes.

这种受体蛋白在骨细胞上尤其丰富。

In between neighboring lamellae, there are spaces called lacunae, which contain bone cells called osteocytes.

相邻的同心薄片细胞之间的空间叫做陷窝，其中包含骨细胞。

First, the osteocytes release chemical signals that direct osteoclasts to the site of the damage.

首先，骨细胞释放化学信号，将破骨细胞引导到损伤部位。

In microgravity, osteocytes aren't getting much loading stimuli, because less gravity means less weight.

在微重力下，骨细胞不会受到太多负荷刺激，因为重力越小意味着体重越轻。

As tiny as they are, these little gaps are where the real work of your skeletal system gets done, because they house your osteocytes.

尽管它们很小，但这些小缝隙是你骨骼系统真正工作完成的地方，因为它们存放着你的骨细胞。

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

最后，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。

The supervisors of this process are those osteocytes, which kick things off when they sense stress and strain, or respond to mechanical stimuli, like the weightlessness of space, or the impact of running on pavement.

这个过程的监督者是那些骨细胞，当它们感觉到压力和应变时，它们会启动东西，或者对机械刺激做出反应，比如太空的失重，或者在人行道上跑步的影响。

So, say you're out running and something happens — nothing to be alarmed about! — but suddenly the osteocytes in your femur detect a tiny, microscopic fracture, and initiate the remodeling process to fix it up.

假设你出去跑步，发生了什么事——没什么好担心的！——但是突然，你股骨中的骨细胞检测到一个微小的、显微的骨折，并启动重塑过程来修复它。

MSCs differentiate into adipocytes, osteocytes, chondrocytes, tenocytes, marrow stromal cells, muscle, and perhaps neuronal cells and are being used in early clinical trials to enhance bone marrow grafting and to suppress graft-versus-host disease in allogeneic bone marrow transplants.

MSCs分化成脂肪细胞，骨细胞，软骨细胞，肌腱细胞，骨髓基质细胞，肌肉和神经细胞，并用于早期临床试验，以增强骨髓移植和抑制同种异体骨髓移植中的移植物抗宿主病。
