成骨

Results The parietal bone of the 9th-week fetuses was a layer of mesenchyme membrane with positive BMP immunoreactivity. In tile parietal hones of 10th to 36 week fetuses, BMP positive immunoreactivity was found in osteoblasts, newly-born osteocytes and periosteum.

结果 第9 w胎儿顶骨为一片间充质膜，呈BMP阳性反应；第10~36 w胎儿顶骨内BMP阳性反应主要见于成骨细胞、新生骨细胞及骨膜中。

But interestingly, this proliferation activity was not observed in 10% NCS-MEM or 4% BSA-serum free MEM.

有趣的是sOGP在体外的成骨活性作用必须有血清白蛋白和血清中某些因子的参与。

The CBFA1 knockout mice showed no osteogenesis and had maturational disturbance of chondrocytes.

CBFA1基因敲除的小鼠缺乏膜内和软骨内成骨，软骨的成熟及分化也受到了严重干扰。

Part 1: The animals were randomly divided into 2 groups: Group A have no latency period and group B have a 7 days latency period.

METHODS: The osteoblasts were harvested from the frontal bone of 15-day SPF chicken embryos by the enzyme digestion, and treated with various mass concentrations of estrogen (0, 5, 10, 20, 100, 200, 400, 800, 2 000, 20 000 ng/L) and letrozole (0, 5, 10, 25, 50, 100, 250, 500, 1 000, 5 000 μg /L).

取15日龄SPF鸡胚，酶消化法获取鸡胚额骨成骨细胞，分别采用不同质量浓度雌激素(0，5，10，20，100，200，400，800，2 000，20 000 ng/L)和来曲唑(0，5，10，25，50，100，250，500，1 000，5 000 μg /L)处理。

Exposure of these cells to above-mentioned inductive agents resulted in obvious morphological change and an increase in expression of AFP and ALB.

在经典的诱导条件下，人胎骨髓MSCs可快速向脂肪及成骨细胞分化；在上述诱导条件下，人胎肝MSCs可分化为类肝细胞，表达特异性抗原甲胎蛋白和白蛋白。
