中文摘要:
目的:应用组织块与混合酶消化联合使用进行大鼠颅骨成骨细胞体外培养。
方法:取新生2～3d的SD大鼠颅骨剪碎依次用不同浓度的胰蛋白酶和Ⅱ型胶原酶混合分2次对颅骨进行消化。纯化、接种后进行原代和传代培养并对细胞进行鉴定。
结果: 原代培养的细胞ALP染色阳性区域可以达90%以上,传代培养后细胞阳性率为100%。18d左右有钙结节形成。电镜观察示细胞表面有微绒毛,粗面内质网丰富。原代培养细胞BMP兔疫组化呈弱阳性表达,传代培养后细胞BMP表达逐渐增强,以第5代左右细胞表达强度最高。
结论:改良组织块混合酶消化法成骨细胞培养具有细胞成分单一、表型稳定的特点。可为成骨细胞的代谢和生理的体外研究提供高纯度的细胞。 |

ABSTRACT
Objective:To investigate possibility of culture of osteoblast from rat cranial bone in vitro with modified method which based on the combination of tissue block and mixed enzyme digestion
Methods:The newly born SD rats were sacrificed and the cranial bones of the rats were obtained and cut to blocks of 1 mm× 1 mm.Then the blocks were digested by collagenase combined with trypsogen two times with 10 minutes for the first time and 30 minutes for the second time. The ratio of collagenase to trypsogen is 3 to 2 for the first time,3 to 1 for the second time, respectively. ALP stains for the cultured cells and TEM investigation were performed to determine the activity of osteoblast.
Results:The area positive for ALP staining is no less than 90% in the primary culture and almost 100% in the subculture.Calcium nodule appeared on the 18th days.Ultrastructural investigations showed that there are microvillus on the surface and plenty of rough endo-plasmic reticulum in cells. BMP-immunoeactivity was detected in the primary culture cells and increased gradually and peaked in fifth subculture using immunocytochemical technique.
Conclusion:The modified culture of osteoblastic-like cells has the advantages of single component and stable phenotype, therefore can be used for the study of metabolism and physiology of osteoblast in vitro. |
