文题释义:
雌激素:是一种男女均可产生的激素,肾上腺皮质也产生少数雌激素。女性进入青春期后,卵巢开始分泌雌激素,以促进阴道、子宫、输卵管和卵巢本身的发育,同时子宫内膜增厚而产生月经。雌激素还能促使皮下脂肪富集,体态丰满;乳腺增生,乳头、乳晕颜色变深,并产生性欲;促使体内钠和水的潴留,骨中钙的沉积等。男性的睾丸酮激素少部分可转化为雌激素。
Ⅰ型胶原:属于成纤维胶原,含量丰富,存在于多种结缔组织中,它具有多方面的生物活性,不仅是非常重要的组织支持物,而且是细胞外间质的重要成分。研究表明,Ⅰ型胶原生物相容性好,降解速度可调,而且可参与组织修复,是一类优良的可引导组织再生的生物材料。Ⅰ型胶原作为体外细胞培养支架时,有促进细胞黏附和诱导生长分化的作用,是良好的培养黏附剂。另外,它的降解产物还能被细胞利用合成新的基质。
摘要
背景:
研究发现骨髓来源的间充质干细胞与牙周膜细胞体外共培养后,可分化为牙周膜纤维细胞。研究提示雌激素具有影响骨髓组织再生的能力。
目的:观察雌激素对骨髓间充质干细胞成骨及成纤维相关因子碱性磷酸酶、Ⅰ型胶原、Ⅲ型胶原蛋白的影响。
方法:体外培养比格犬骨髓间充质干细胞并鉴定,利用一定浓度雌激素对比格犬骨髓间充质干细胞进行干预,RT-PCR检测成骨、成纤维相关基因的表达变化,Western Blot 检测雌激素对目的基因蛋白表达的影响。
结果与结论:①雌激素可以增加Ⅰ型胶原、Ⅲ型胶原mRNA及蛋白的表达,对于Ⅰ型胶原来说,雌激素的作用更为显著;②雌激素对碱性磷酸酶基因及蛋白的表达没有影响;③目的蛋白的表达变化和基因变化趋势基本一致;④雌激素可以刺激骨髓间充质干细胞向成纤维细胞方向分化,同时对促进牙周膜矿化的基因无刺激作用。

Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells have been shown to be differentiated into periodontal ligament fibroblasts when co-cultured with periodontal ligament cells. Existing studies have shown that estrogen has the ability to influence bone marrow regeneration.
OBJECTIVE: To investigate the effects of estrogen on osteogenesis and fibroblast-related factors alkaline phosphatase, type I and III collagen in bone marrow mesenchymal stem cells.
METHODS: Bone marrow mesenchymal stem cells isolated from Beagle dogs were treated with estrogen. Osteogenesis and fibroblast-related mRNA and protein expression of bone marrow mesenchymal stem cells was determined by RT-PCR and western blot assay, respectively.
RESULTS AND CONCLUSION: mRNA and protein expression of type I and III collagen in bone marrow mesenchymal stem cells was upregulated following estrogen treatment; especially, in contrast with type III collagen, the changes of type I collagen were more obvious. Estrogen did not influence mRNA and protein expression of alkaline phosphatase. These findings suggest that estrogen promotes the differentiation of bone marrow mesenchymal stem cells into fibroblasts, whereas does not impact the genes involved in parodontium mineralization.
