J Endod:靶向牙髓成纤维细胞可成为牙本质-牙髓再生的潜在治疗策略

2017-08-13 MedSci MedSci原创

成纤维细胞是牙髓组织中最丰富的细胞种群。尽管其他类型的细胞已经得到广泛研究,如:成牙本质细胞和干细胞,但是成纤维细胞却很少被关注,虽然它对于调节牙髓在正常和病理条件下的生物学活性和功能起到了主要作用。

成纤维细胞是牙髓组织中最丰富的细胞种群。尽管其他类型的细胞已经得到广泛研究,如:成牙本质细胞和干细胞,但是成纤维细胞却很少被关注,虽然它对于调节牙髓在正常和病理条件下的生物学活性和功能起到了主要作用。

事实上,在生理条件下,牙髓成纤维细胞调节着牙髓的血管生成和神经支配,并且可以通过合成生长因子促进牙髓-牙本质再生、血管生成和神经分布。另外,牙髓成纤维细胞属于非肝非免疫的细胞类型,它们能够合成所有产生生物活性片段的补体蛋白质,而这些蛋白质对牙髓再生过程起到重要作用,如:C3a, C5a和膜攻击复合物,因此牙髓成纤维细胞也代表一种独特的细胞群。C3a片段参与诱导干细胞和牙髓成纤维细胞的增殖。C5a指引神经萌发和干细胞募集。膜攻击复合物可以直接破坏致龋细菌壁,从而起到修复作用。这些数据表明,牙髓成纤维细胞对牙本质-牙髓组织的调控是通过直接破坏致龋细菌和释放涉及神经萌发、干细胞募集和牙髓再生的生物活性片段而起到核心作用。

结论:这篇研究显示,靶向牙髓成纤维细胞代表一种现实可行的策略来诱导完整的牙本质-牙髓再生。

J Endod:对未发育完全恒牙的治疗方案选择的认知

目前,对于未发育完全恒牙的牙髓坏死治疗首选根尖诱导成形术或者牙髓再生术。这篇研究的目的是为了调查牙髓病科医师对这2种治疗方法的选择应用。

J Periodontal Implant Sci:牙周和牙髓病变可影响拔牙窝的愈合

本研究目的是评估牙周病和牙髓病病史的患牙拔除后拔牙窝的愈合情况。选取5只成年比格犬,以其下颌第四前磨牙为实验部位。在第一磨牙部位使用钢丝结扎和牙髓暴露3个月诱导牙周牙髓病变(实验组)。健侧前磨牙部位为健康对照组。然后微创拔除下颌第四颗前磨牙,仔细清创。分别于术后1, 7, 30、60、90天处死动物,观察动物拔牙窝的愈合情况。使用 X光线照相术、扫描电子显微镜、组织学和histometry来对比健

J Endod:新发现:牙髓的修复愈合存在肌成纤维细胞的参与

肌成纤维细胞表达α平滑肌肌动蛋白(α-SMA),它在伤口愈合过程中扮演着重要角色。肌成纤维细胞的分化受到转移生长因子β1(TGF-β1)和纤连蛋白胞外域A剪接变体(EDA-FN)的联合调控。然而,到目前为止,肌成纤维细胞在牙髓修复愈合中的作用还不清楚。为此,在本项实验中,研究者们对大鼠实施活髓切断术后,分析α-SMA阳性细胞的表达特征,检测TGF-β1、EDA-FN和α-SMA的表达水平变化,以此

J Dent Res:IGF-1通过介导EphrinB1活性调节第三期牙本质的形成

Eph受体为受体酪氨酸激酶亚家族成员,它们可以被跨膜配体-ephrins所激活。项目实施者早先的研究表明,ephrinB1-EphB2之间的相互作用可以促进体外培养的牙髓细胞(DPCs)的成牙本质/成骨分化。这篇研究的目的是为了阐明EphrinB1/ephB2系统在体内/体外调节第三期牙本质形成的分子机制。

专访|梁景平:牙髓坏死也能“把根留住”,根管治疗拯救坏牙

牙疼不是病,疼起来真要命。对于牙髓坏死和根尖周组织感染的严重龋病患者来说,钻心一般的疼痛,让很多人招架不住,只得将牙齿连根拔起,安装义齿。而随着根管治疗术的不断发展,尤其是显微根管治疗成功率明显提高,牙髓坏死的牙齿,通过治疗可以把根留住,从而恢复牙齿的形态和功能。上海交通大学医学院附属第九人民医院牙体牙髓科主任梁景平教授,从事根管治疗近四十余年,在镍钛根管预备及弯曲根管治疗和显微根管治疗方面积累了

J Endod:牙髓来源的间充质干细胞特性与培养条件的影响

牙髓间充质干细胞(DPMSCs)高表达间充质干细胞标记物,并且具有分化为神经细胞、成骨细胞、脂肪细胞和成软骨细胞的潜能。因此,DPMSCs被认为适合应用于组织再生。集落分离法通常被用来相对大量收集异种DPMSCs。而同源DPMSCs可以利用抗间充质干细胞标记物抗体通过荧光活化细胞分选系统进行分离,虽然此种方法分离的细胞产率很低。DPMSCs的数量和质量对再生疗法均十分重要,并且细胞培养方法还有待于
