摘要： 脊椎动物胚胎期骨与关节系统的发生是一种复杂生命现象，起始于中胚层间充质细胞的定向聚集，形成肢芽，然后在一系列作用因子的调控下，肢芽内细胞进一步分化，形成具有骨骼雏形的软骨原基，后者经软骨内骨化发育成骨。四肢骨大多是以这种方式发生的，四肢的滑膜关节系统也随骨骼的发生而形成。详细阐述了近年来对肢体骨与关节系统发生各步骤相关调控机制方面的研究进展。Abstract: The embryonic development of bone and joint involves in complicated events for vertebrate limb. It originates from determined condensation of mesenchymal cells from lateral mesoderm. These cells and the overlying ectodermal jacket form limb buds at presumptive limb levels. Then, under the control of systemic factors, mesenchymal cells aggregate and differentiate to form catilage blastemal elements that prefigure skeletal limb components. The latter develops into skeleton through endochondral ossification. The majority of the bones of the limb form by the endochondral mechanism. The formation of synovial joint system and bone development occur simultaneously. This article reviewed the progress on the related control mechanism in the development of bone and joint recently.
