成骨

Osteoblasts are seen lining the irregular trabeculae, and there is an osteoclast near the center.

不规则骨小梁周围可见成骨细胞排列，中心部位可见破骨细胞。

By histological examination, it was found that in HAC group, there were granulation tissue, fibrous tissue and newly formed vessels grew into the pores and the osteoblasts formed osseous trabeculae.

组织学显示在不同阶段，多孔HAC植片标本有肉芽组织、纤维组织和新生血管向微孔中生长及成骨细胞形成的骨小梁。

Results There existed new cartilage and new immature bone tissue in the bone substitute in 4 weeks after operation, as well as mass of cartilageous cells,osteoblasts, collagen tissue and more small vessels were seen. In the period of 8 to 16 weeks after operation,new bone was formed continuously, artificial bone gradually reconstructed to mature lamellar bone,bone trabeculae and medullary cavity,etc.

结果 CPC植入后4周有新生软骨形成及未成熟的骨组织，可见大量的软骨细胞、成骨细胞、胶原组织及较多的小血管。8～16周新骨继续生成，人工骨逐渐改建为成熟的板层骨、骨小梁和髓腔结构。

The results of microimage analysis showed that tile average grey value (0~255, black~white) of BMP positive osteoblasts and trabeculae of fetal parietal bones increased with the increase of gestational age.

图像分析表明：胎儿顶骨内BMP阳性的骨小梁及成骨细胞的平均灰度值(0~255， black~white)随胎龄增加而呈上升趋势。

RESULTS: At 7 and 14 days following osteogenic induction, a significant positive reaction to alkaline phosphatase staining was detected, with calcium nodus.

结果：成骨诱导7， 14d，经诱导的骨髓基质干细胞和脂肪间充质干细胞呈碱性磷酸酶阳性，有钙结节形成，未诱导组呈阴性。
