研究目的:

本研究拟应用牙周组织特异性ECM并结合“分层构建、整体复合”策略重塑牙周再生微环境,开展基础研究、临床前动物实验和前瞻性随机对照临床试验,使用两种ECM对hPDLSCs进行干预,然后将ECM/hPDLSCs复合物分层移植入牙周缺损处,评估该方法的安全性、有效性,以期解决牙周再生的瓶颈问题。  

Objectives of Study:

This study aims to apply periodontal tissue-specific extracellular matrix (ECM) and combine it with a "layered construction, overall composite" strategy to reshape the periodontal regenerative microenvironment. The research will encompass basic studies, preclinical animal experiments, and prospective randomized controlled clinical trials. Two types of ECM will be used to intervene with human periodontal ligament stem cells (hPDLSCs), after which the ECM/hPDLSC composites will be transplanted in layers into periodontal defects. The safety and efficacy of this method will be evaluated with the goal of addressing the bottleneck issues in periodontal regeneration.

药物成份或治疗方案详述:

ECM的制备与保存,将不同供体的牙周膜细胞(PDLCs)和骨髓细胞(BMCs)复苏,将PDLCs和BMCs分别混合培养,目的是消除个体差异,细胞在培养皿中贴壁培养扩增,在细胞培养至第四代时,按照专利《一种牙周组织特异性细胞外基质ECM的制备方法及其应用》的方法进行基质诱导和脱细胞处理,制备牙周膜来源(PDLCs)-ECM和骨髓细来源(BMCs)-ECM。具体方法如下:将PDLCs和BMCs分别以2×10^4个/孔的密度接种于六孔板上,24小时后细胞基本贴壁,隔天换液。待细胞长至80%后,更换培养液为成膜培养液(含抗坏血酸50μg/mL)。约10天后,可见培养皿底有一层乳白色半透明的膜状物。小心洗涤PBS两遍,用含20mMNH4OH的无菌1%TritonX-100进行脱细胞步骤。37°C条件下,加入脱细胞处理液,放置5min,弃去脱细胞处理液,PBS小心洗涤两遍,遂可得牙周膜来源的脱细胞的细胞外基质(hP-ECM)和骨髓来源的脱细胞的细胞外基质(hB-ECM)。通过普通光学显微镜观察ECMs的大体形态;通过免疫荧光对细胞核进行染色(DAPI)染色,荧光显微镜观察脱细胞情况;通过透射电镜、扫描电镜、原子力显微镜对这些ECMs的表面形态以及超微结构进行观测。使加入2mlPBS(内含两性霉素0.25mg/L,100U/mL青霉素,100mg/L链霉素),在4°C条件下保存1个月备用。 

Description for medicine or protocol of treatment in detail:

The preparation of ECM involves the revival of periodontal ligament cells (PDLCs) and bone marrow cells (BMCs) from different donors. PDLCs and BMCs are co-cultured separately with the aim to eliminate individual differences. The cells are expanded by adherent culture in dishes. When the cells reach the fourth passage, they undergo matrix induction and decellularization according to the method described in the patent "A Preparation Method and Application of Periodontal Tissue-Specific Extracellular Matrix (ECM)". This process prepares periodontal ligament-derived (PDLCs)-ECM and bone marrow-derived (BMCs)-ECM. The detailed procedures are as follows: PDLCs and BMCs are seeded at a density of 2×10^4 cells per well into six-well plates. After approximately 24 hours, the cells have mostly adhered to the wells, and the medium is changed every other day. Once the cells reach about 80% confluence, the culture medium is replaced with film-forming medium containing 50 μg/mL ascorbic acid. Around ten days later, a layer of milky white translucent film can be observed at the bottom of the culture dish. Carefully wash twice with PBS, then perform the decellularization step using sterile 1% Triton X-100 containing 20 mM NH4OH. At 37°C, add the decellularization solution for 5 minutes, then discard it and carefully wash twice again with PBS. This yields the decellularized extracellular matrices derived from periodontal ligament cells (hP-ECM) and bone marrow cells (hB-ECM). The gross morphology of the ECMs is examined under an optical microscope; the nuclei are stained with DAPI for immunofluorescence microscopy to observe the decellularization status. Transmission electron microscopy, scanning electron microscopy, and atomic force microscopy are used to examine the surface morphology and ultrastructure of these ECMs. Finally, add 2 mL of PBS (containing amphotericin B at 0.25 mg/L, penicillin at 100 U/mL, and streptomycin at 100 mg/L) and store the ECMs at 4°C for up to one month for future use.

随机方法(请说明由何人用什么方法产生随机序列):

由一名研究者使用计算机软件Excel生成随机数序列 步骤 1: 准备数据,打开Excel 并创建一个新的工作表,在第一列()输入参与者的标识符(如ID号、姓名等)。 步骤 2: 生成随机数,在B列中生成随机数。在B1单元格中输入公式“=RAND()”,并向下拖动以填充至所有参与者的行:这将为每个参与者生成一个介于0和1之间的随机小数。 步骤 3: 排序,选择两列数据(即A列中的参与者标识符和B列中的随机数)。点击“数据”选项卡上的“排序”按钮。在弹出的对话框中,选择按B列(随机数)排序,升序或降序都可以,点击确定。 步骤 4: 分配组别,根据排序后的顺序分配组别。可以在C列中进行手动分配,或者使用公式自动分配。例如,在C1单元格中输入公式“=IF(MOD(ROW(),2)=1, "Group A", "Group B")”,并向下拖动以填充,这个公式会交替分组。

Randomization Procedure (please state who generates the random number sequence and by what method):

A researcher generates a random number sequence using the computer software Excel. Step 1: Prepare Data. Open Excel and create a new worksheet. In the first column (Column A), enter the identifiers for the participants (such as ID numbers, names, etc.). Step 2: Generate Random Numbers. Generate random numbers in Column B. In cell B1, input the formula =RAND(), and drag it down to fill all rows corresponding to the participants. This will generate a random decimal number between 0 and 1 for each participant. Step 3: Sort Data. Select both columns of data (i.e., Column A with participant identifiers and Column B with random numbers). Click on the "Sort" button in the "Data" tab. In the dialog box that appears, choose to sort by Column B (random numbers) in either ascending or descending order, then click OK. Step 4: Assign Groups. Assign groups based on the sorted order. You can do this manually in Column C or use a formula for automatic assignment. For example, in cell C1, input the formula =IF(MOD(ROW(),2)=1, "Group A", "Group B") and drag it down to fill. This formula will alternate the assignment between "Group A" and "Group B".

盲法:

在本实验中,受试者将被施加盲法。在受试者接受治疗前以及接受治疗时,研究者将不会告知受试者其被进入的是实验组或对照组。在随访过程中,受试者也不允许被告知自己属于实验组或对照组,直至随访周期结束。

Blinding:

In this trial, participants will be blinded. Before and during the treatment, researchers will not inform the participants whether they have been assigned to the experimental group or the control group. Throughout the follow-up period, participants will also not be informed of their group assignment until the end of the follow-up period.
