文题释义:
四环素:
具有抑制基质金属蛋白酶活性、抑制骨吸收、可恢复成骨细胞的结构和功能,具有极强的骨亲活性,可促进处于病理状态下骨组织生长的活性,影响成骨细胞的结构和功能,恢复病理状态下成骨细胞的正常结构,这些特性使其在骨科极具潜在的临床应用价值,尤其是在组织工程骨开发和应用中有着广阔的临床应用前景。
细胞增殖检测方法:主要有活细胞计数法、MTT法、同位素3H-TdR掺入法及BrdU等方法,其中细胞计数法直观简单,但计数时可能混有已凋亡的细胞,同时药物的干扰可能也会抑制凋亡的发生,因而最终不能客观证明检测的细胞是否在增殖;3H-TdR掺入法虽具有灵敏度高、稳定性好等特点,但步骤较多,需要特殊设备,并且具有放射性;BrdU法需要固定和变性,易造成细胞DNA双链断裂影响结果;MTT法是利用活细胞线粒体中的琥珀酸脱氢酶,将外源性的MTT还原为难溶性的蓝紫结晶物并沉积在细胞中,而死细胞无此功能,因而能够反映活细胞在数量上的变化,同时该法还具有灵敏度高、操作简便、快速的特点。

 

摘要
背景:
研究表明,低浓度四环素可促进体外培养的人胚成骨细胞活性及增殖,增加且加强细胞合成Ⅰ型胶原、骨钙素等促进骨生成的物质。
目的:观察盐酸四环素体外对大鼠骨髓间充质干细胞增殖的作用。
方法:取第3代SD大鼠骨髓间充质干细胞,分2组干预,对照组加入含胎牛血清的完全培养基培养,实验组加入含盐酸四环素及胎牛血清的完全培养基培养。培养1-8 d,采用MTT法、细胞计数法检测两组细胞增殖活性。
结果与结论:①细胞计数法:随着培养时间的延长,两组细胞数量逐渐增加,实验组培养4-8 d的细胞数量高于对照组(P < 0.05);②MTT法:两组细胞数量均随培养时间的延长而增加,第1天为细胞潜伏期,3-6 d为对数生长期,第7天,对照组细胞进入平台期,实验组细胞继续增殖,实验组培养5-8 d的细胞增殖高于对照组(P < 0.05);③结果表明:盐酸四环素可促进骨髓间充质干细胞的增殖。

Abstract:

BACKGROUND: Tetracycline hydrochloride is shown to promote viability and proliferation of human embryonic osteoblasts cultured in vitro, increase the production of type I collage and osteocalcin.
OBJECTIVE: To study the proliferation activity of bone marrow mesenchymal stem cells (BMSCs) cultured by tetracycline hydrochloride in vitro.
METHODS: Passage 3 BMSCs from Sprague-Dawley rats were cultured and divided into two groups: cells in control group were cultured in complete medium containing fetal bovine serum, and those in experimental group were cultured in complete medium containing tetracycline hydrochloride. After days 1-8 of culture, MTT and cell counting assay were used to detect cell viability and proliferation in the two groups.
RESULTS AND CONCLUSION: (1) Cell counting assay: with time, the number of cells in both groups was increased, but the cell number in the experimental group was higher than that in the control group at days 4-8 of culture (P < 0.05). (2) MTT assay: With time, the number of cells in both groups was increased: incubation period was at day 1, logarithmic growth period was within days 3-6, and plateau period began at day 7. Then, the cells continued to proliferate, and the cell proliferation was higher in the experimental group than the control group at days 5-8 of culture (P < 0.05). To conclude, tetracycline hydrochloride can significantly enhance BMSCs proliferation.
