Osteoclasts are known for their role in bone resorption. A study now shows that a vascular–associated osteoclast subtype at the growth plate also regulates blood vessel growth in bone and is supported by type H endothelial cells. These type H capillaries, in turn, release proteinases that promote cartilage degradation.
破骨细胞因其在骨吸收中的作用而闻名。一项研究表明,生长板处一种与血管相关的破骨细胞亚型也可调节骨内血管生长,并得到H型内皮细胞的支持。反过来,这些H型毛细血管会释放促进软骨降解的蛋白酶。
