文题释义:
盐酸四环素的药理作用:
口服吸收不完全。本品可透入胎盘和进入乳汁。盐酸四环素是广谱抗生素,起抑菌作用,其抗菌谱包括许多革兰阳性和阴性菌、立克次体、支原体、衣原体、放线菌等。盐酸四环素现主要用于立克次体病、布氏杆菌病、淋巴肉芽肿、支原体肺炎、螺旋体病、衣原体病,也可用于敏感的革兰阳性菌或革兰阴性菌所引起的轻症感染。
碱性磷酸酶(ALP或AKP):是广泛分布于人体肝脏、骨骼、肠、肾和胎盘等组织经肝脏向胆外排出的一种酶。这种酶能催化核酸分子脱掉5'磷酸基团,从而使DNA或RNA片段的5'-P末端转换成5’-OH末端。但它不是单一的酶,而是一组同功酶。目前已发现有AKP1、AKP2、AKP3、AKP4、AKP5与AKP6六种同功酶。其中第1、2、6种均来自肝脏,第3种来自骨细胞,第4种产生于胎盘及癌细胞,而第5种则来自小肠绒毛上皮与成纤维细胞。

 

摘要
背景:
盐酸四环素不仅具有促进骨髓间充质干细胞增殖的作用,还具有极强的骨亲活性。研究盐酸四环素诱导骨髓间充质干细胞向成骨细胞分化,可为获得骨组织工程细胞提供新方法。
目的:观察体外盐酸四环素对大鼠骨髓间充质干细胞向成骨细胞分化的作用。
方法:骨髓全血细胞贴壁法分离培养大鼠骨髓间充质干细胞,通过细胞形态和骨髓间充质干细胞标志物CD34、CD45、CD90、CD29流式检测对骨髓间充质干细胞进行鉴定;取第3代骨髓间充质干细胞与盐酸四环素共培养,以含体积分数10%FBS的L-DMEM的完全培养基培养做对照组。通过检测碱性磷酸酶活性、Ⅰ型胶原和骨钙素免疫组织化学染色、茜素红矿化钙结节组织化学染色、Ⅰ型胶原蛋白和骨钙素的RT-PCR的基因表达,研究盐酸四环素对骨髓间充质干细胞的成骨诱导分化活性。
结果与结论:①盐酸四环素能够持续促进骨髓间充质干细胞的碱性磷酸酶活性增加,与对照组比较具有显著性差异;②盐酸四环素诱导培养骨髓间充质干细胞 21 d,Ⅰ型胶原蛋白和骨钙素染色表达阳性,茜素红染色出现红色钙结节,RT-PCR检测Ⅰ型胶原蛋白和骨钙素基因表达;对照组程阴性表达;③结果表明,盐酸四环素具有明显促进骨髓间充质干细胞成骨诱导分化的作用。

Abstract:

BACKGROUND: Tetracycline hydrochloride not only promotes the proliferation of bone marrow mesenchymal stem cells (BMSCs), but also has a strong bone activity. Studies on the osteogenic differentiation of BMSCs induced by tetracycline hydrochloride will provide a new cell source for bone tissue engineering.
OBJECTIVE: To observe the induction and differentiation activity of BMSCs into osteoblasts cultured by tetracycline hydrochloride in vitro.
METHODS: BMSCs were separated and expanded by whole bone marrow adherent method and identified by cell morphology and BMSCs cell markers CD34, CD45, CD90, CD29. Passage 3 BMSCs were collected and cultured with tetracycline hydrochloride (experimental group) or cultured in L-DMEM containing 10% fetal bovine serum (control group). Osteogenic induction and differentiation activity of BMSCs cultured by tetracycline hydrochloride were detected by alkaline phosphatase activity detection, collagen I and osteocalcin immunohistochemistry staining, alizarin red staining of mineralized calcium nodules, and detection of collagen I and osteocalcin gene expression by RT-PCR.
RESULTS AND CONCLUSION: Tetracycline hydrochloride continuously promoted alkaline phosphatase activity in the BMSCs, significantly different from that in the control group. After 21 days of culture, positive expression of collagen I and osteocalcin proteins, red calcium nodules shown by alizarin red staining, and mRNA expression of collagen I and osteocalcin were observed in the experimental group, while the negative expression was found in the control group. In conclusion, tetracycline hydrochloride has a significant role to promote the osteogenic differentiation of BMSCs.
