The late embryonic and post partum development of the rat knee-joint has been studied by the transmission and scanning electron microscope. Undergoing a transformation in the sense of functional adaption to extrauterine life there is a final breakdown of the mesenchym cell layer (interzone) which separates in the embryo the anlagen of the bones. Its is followed by an accelerated growth of the collagen-containing intercellular substance which finally forms the surface.
利用透射电子显微镜和扫描电子显微镜对大鼠膝关节的胚胎后期和产后发育进行了研究。随着膝关节在功能上适应宫外生活，将胚胎期骨骼原基分隔开的间充质细胞层（中间带）最终瓦解。随后，含胶原蛋白的细胞间物质加速生长，最终形成关节表面。
