文题释义:

骨髓干细胞的免疫学特征:①表达组织相容性复合物Ⅰ而不表达组织相容性复合物Ⅱ,且缺乏共刺激因子的表达,免疫原性较弱。②能直接或间接抑制T细胞的功能,同时对CD4+和CD8+淋巴细胞也有抑制作用。③具有免疫调节的功能。

基质细胞衍生因子1:是一类对免疫细胞有趋化作用的小分子蛋白,属于CXC趋化因子之一,具有广泛的生物学活性,可以诱导骨髓间充质干细胞向具有牙周膜纤维细胞特性的方向分化。基于以往研究证据,作者推测,基质细胞衍生因子1应用在骨髓干细胞介导的牙周膜再生的组织工程中能够产生积极作用。

 

背景:基质细胞衍生因子1是一类对免疫细胞有趋化作用的小分子蛋白,具有广泛的生物学活性,对骨髓干细胞和牙周膜细胞都有趋化作用。
目的:观察基质细胞衍生因子1对比格犬骨髓干细胞增殖的影响并探讨最佳质量浓度。
方法:利用100,200,300 μg/L基质细胞衍生因子1对比格犬骨髓干细胞进行干预,MTT比色实验检测骨髓干细胞的增殖情况,筛选出最佳质量浓度,再次采用MTT比色实验检测最佳质量浓度干预后骨髓干细胞的增殖情况。

结果与结论:基质细胞衍生因子1在100,200,300 μg/L时对骨髓干细胞均有促进作用,但200 μg/L与300 μg/L效果更为显著,且这两者差异无显著性意义,因此选择200 μg/L作为最佳质量浓度。相对于空白对照组来说,200 μg/L最佳质量浓度组细胞增殖明显。结果表明基质细胞衍生因子1能促进骨髓干细胞的增殖,且质量浓度为200 μg/L时促增殖作用最显著。 ORCID: 0000-0002-2899-5703 (陈松龄)

Abstract:

BACKGROUND: Stromal cell derived factor-1 is a small molecular protein with a wide range of biological activity that can cause immune cell chemotaxis, and it also has a chemotactic effect on bone marrow stem cells and periodontal ligament cells.
OBJECTIVE: To investigate the effect of stromal cell derived factor-1 with different concentrations on the proliferation of bone marrow stem cells and to probe the best concentration.
METHODS: Bone marrow stem cells from beagle dogs were cultured in vitro and stimulated by different concentrations of stromal cell derived factor-1 (100, 200, 300 μg/L). MTT was used to detect the influence of stromal cell derived factor-1 on the proliferation of bone marrow stem cells so as to screen the best concentration of stromal cell derived factor-1. Then, stromal cell derived factor-1 at the best concentrations was used to intervene the bone marrow stem cells, and MTT was used again to detect the proliferation of bone marrow stem cells.
RESULTS AND CONCLUSION: Stromal cell derived factor-1 at concentrations of 100, 200, 300 μg/L could promote the proliferation of bone marrow stem cells, and the effect was more notable at 200 and
300 μg/L but with no significant difference. Therefore, 200 μg/L was considered to be the best concentration of stromal cell derived factor-1 for intervention of bone marrow stem cells. Compared with the blank control group, 200 μg/L stromal cell derived factor-1 could significantly promote the proliferation of bone marrow stem cells. Taken together, stromal cell derived factor-1 can promote the proliferation of bone marrow stem cells, and its best concentration is 200 μg/L.
