摘要:

文题释义:
锻烧骨:通过物理及化学的方法去除骨内的有机物成分,而保留其无机物成分,通过这种方法可以有效增加材料的生物相容性。
巨噬细胞极化:巨噬细胞是一种极具异质性的细胞群体,在体内复杂的微环境中,巨噬细胞存在一系列连续的功能状态,而M1型和M2型巨噬细胞是这一连续状态的两个极端,在异物反应中巨噬细胞M1和M2两个表型处于动态平衡状态,是目前免疫研究的热点。

背景:异物反应会导致材料植入失败,近些年来对于免疫学的研究逐渐成为热点,选择具有良好免疫性能的支架材料,对于骨缺损修复具有重要意义。
目的:探讨去抗原处理的煅烧马鹿角松质骨及未去抗原处理的马鹿角对骨髓来源M1型巨噬细胞生物行为的影响。
方法:经过物理及化学方法制备煅烧马鹿角松质骨,通过X射线光电子能谱、傅里叶变换红外光谱检测材料理化性质,制备2种材料浸提液并检测浸提液中Ca、P、Mg的元素水平。体外诱导培养骨髓来源巨噬细胞并在脂多糖和干扰素γ刺激下极化为M1型巨噬细胞,然后与各组浸提液共培养,对照组用单纯IMDM完全培养基共培养,CCK-8检测细胞存活率、流式细胞术检测细胞M1型标志物表达率、qPCR检测巨噬细胞相关基因表达水平。
结果与结论:①去抗原马鹿角组Ca、P、Mg元素水平高于马鹿角组;②去抗原马鹿角组和马鹿角组主要官能团为OH-、PO43-、CO32 -;③共培养1,3,7 d各组M1型巨噬细胞存活率差异无显著性意义;④共培养1 d时,去抗原马鹿角组细胞表面标志物CD16/32表达率低于对照组;⑤共培养1,3 d时,去抗原马鹿角组促炎因子肿瘤坏死因子α和白细胞介素6的表达明显低于对照组;共培养3 d时,去抗原马鹿角组M2型巨噬细胞主要标记物CD206的表达量明显高于对照组;而在共培养1,3 d时马鹿角组的肿瘤坏死因子α和白细胞介素6表达或与对照组无差异或明显高于对照组,在CD206因子表达方面均与对照组无差异;⑥结果表明,去抗原马鹿角松质骨粉末浸提液可降低M1型巨噬细胞相关促炎因子的表达并促进其向M2型巨噬细胞极化。

Abstract: BACKGROUND: Foreign body reactions will lead to the failure of material implantation. In recent years, research on immunity has gradually become a hot spot. It is of great significance to select scaffold materials with good immune properties for the development of bone defect repair.  
OBJECTIVE: To investigate the effects of calcinated antler cancellous bone and untreated antler bone on the biological behavior of bone marrow-derived M1 macrophages.
METHODS:  Calcinated antler cancellous bone was prepared by physical and chemical methods. The physical and chemical properties of calcinated antler cancellous bone and untreated antler bone were detected by X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. The extracts of calcinated antler cancellous bone and untreated antler bone were prepared and the contents of Ca, P and Mg in the extracts were determined. Bone marrow-derived macrophages were cultured in vitro and polarized into M1 macrophages under lipopolysaccharide and interferon γ stimulation. These cells were then co-cultured with different extracts in calcinated antler cancellous bone and untreated antler bone groups, while co-cultured with an IMDM medium in control group, followed by cell counting kit-8 detection of cell survival, flow cytometry detection of M1 markers, and qPCR detection of macrophage-related genes.  
RESULTS AND CONCLUSION: (1) The contents of Ca, P and Mg were higher in the calcinated antler cancellous bone group than the untreated antler bone group. (2) The main functional groups in these two groups included OH-, PO43-, and CO32 -. (3) There was no significant difference in cell survival rate among the three groups for 1, 3, and 7 days of co-culture. (4) The expression rate of CD16/32 was lower in the calcinated antler cancellous bone group than the control group after 1-day co-culture. (5) The expression levels of pro-inflammatory cytokines, tumor necrosis factor-α and interleukin-6 were lower in the calcinated antler cancellous bone group than the control group after 1 and 3 days of co-culture, while there was no significant difference between the untreated antler bone group and the control group. The expression of CD206, a main marker of M2 macrophages, was significantly higher in the calcinated antler cancellous bone group than the control group at 3 days of co-culture, while there was no significant difference between the untreated antler bone group and the control group at 1 and 3 days of co-culture. (6) To conclude, calcinated antler cancellous bone powder extract can reduce the expression of pro-inflammatory cytokines in M1 macrophages and promote their polarization to M2 macrophages.
