Objective: To study the expression of CD44, FN of callus cartilage cell in the healing process of osteoporosis fracture.

目的：探讨骨质疏松性骨折愈合过程中胞内信号因子cd 44及其配体FN在骨痂软骨细胞的表达情况。

Conclusion To grow the cartilage cell on the surface of freeze-dried bone and PLGA chaff constructs maybe form tissue engineering articular cartilage.

结论冻干骨表面粘合plga材料种植软骨细胞有可能形成组织工程化关节软骨。

Objective To forecast the possibility of new cartilage formation by tissue engineering approach with observation of the cartilage cell proliferation on two difference materials.

目的了解两种材料表面软骨细胞的增殖特性预测形成组织工程化关节软骨的可能性。

Histology showed that control group had massive cartilage cell gathering together and bone trabecula disturbance, it had no significant bone cortex and medullary cavity formation.

组织学检查显示：对照组中可见大量团聚软骨细胞、骨小梁紊乱，无明显骨皮质、髓腔形成。

Another type of cell called a chondroblast forms new cartilage.

名叫软骨原细胞的另一种细胞会形成新的软骨。
