These cells are the master regulator of bone remodeling and the most abundant cell type in bone.

这些细胞是骨骼重塑的主控因子，也是骨骼中最丰富的细胞种类。

Now, a new study in mice shows how a hormone secreted by active muscle cells triggers bone remodeling.

现在，一项在老鼠身上进行的新研究揭示了活跃肌肉细胞分泌的激素是如何触发骨骼重塑的。

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。

In this way, exercising stimulates bone remodeling — and ultimately bone strength — so when you're working out, you're building bone as well as muscle.

通过这种方式，锻炼可以刺激骨骼重塑——最终刺激骨骼强度——所以当你锻炼的时候，你在锻炼肌肉的同时也在锻炼骨骼。

These cells work in a kinda similar way, in a process that I'd argue is less stressful than home improvement — it's called bone remodeling.

这些细胞也以类似的方式工作。我认为这个过程比家居装修压力要小。这个过程叫做骨骼重塑。

It can be congenital, meaning that the person is born with it, or acquired, usually due to degenerative disorders like ankylosing spondylitis, where the bones remodel causing intervertebral discs ossification, and the narrowing of the spinal canal.

它可能是先天性的，也就是说患者出生便有这种情况；或是获得性的，通常原因是退行性疾病，如强直性脊柱炎，导致骨重塑，引起椎间盘骨化，进而造成椎管狭窄。
