To observe the effect of serum containing Carapax et Plastrum Testudinis in inducing the differentiation of mesenchymal stem cells of adult rats into neurons.

观察龟板含药血清体外诱导成年大鼠骨髓间充质干细胞分化为神经元的能力。

Objective To observe the effect of seropharmacological plastrum testudinis on the expression of bone morphogenetic protein4(BMP4) of rat mesenchymal stem cells in vitro.

目的龟板有促大鼠骨髓间充质干细胞增殖作用，本研究观察龟板含药血清对MSCs中骨形态发生蛋白4(BMP4)表达的影响。

The growth of rat mesenchymal stem cells with low,middle and high seropharmacological plastrum testudinis were observed separately by means of morphological apperances.

结果BMP4蛋白和mRNA表达相一致，龟板含药血清以浓度依赖方式促进MSC的BMP4 mRNA及其蛋白表达。

Ointment extracted from Plastrum Testudinis was separated by silica gel column chromatography, gradiently eluted by petroleum ether-ethyl acetate, and 16 (Ts-1～Ts-16) components were obtained, which were biologically evaluated by MTT assay and flow cytometry on the proliferation of rat marrow-derived mesenchymal stem cells. Results showed that Ts-12 induced proliferation compared with the control group ( p ＜0.05), while Ts-4 showed inhibitive effect. Other groups showed no significance ( p ＞0.05). GC-MS was used to analyze the chemical components in different groups.

中药龟板提取物浸膏经硅胶柱层析，用石油醚-乙酸乙酯作洗脱剂，梯度洗脱，得到16个组分；采用MTT法和流式细胞技术研究了它们对鼠骨髓间充质干细胞的增殖作用，实验结果显示组分Ts-12具有促进rMSCs增殖的作用( p ＜0.05)，而组分Ts-4则表现出抑制rMSCs增殖的作用( p ＜0.05)，其它样品对rMSCs的增殖作用不显著( p ＞0.05)，不具统计学意义。

To investigate the effects of umbilical cord mesenchymal stem cell transplantation on interstitial pneumonitis in MRL/lpr mice.

目的 探讨脐带间质干细胞对MRL/lpr狼疮鼠间质性肺炎的治疗作用。

BACKGROUND: Researches show that erythropoietin can stimulate the proliferation and protraction of endothelial progenitor cells to form new vessels, so EPO may play an important role in proliferation and differentiation of bone marrow-derived mesenchymal stem cells.

背景：促红细胞生成素能够促进内皮祖细胞增殖、迁延形成新生血管，因此促红细胞生成素可能在骨髓间充质干细胞增殖分化中起重要作用。

To study the effects of pulsed electromagnetic fields on rat mesenchymal stem cells.

探讨脉冲电磁场（PEMFs对大鼠骨髓间充质干细胞的影响。

Results］the gross morphology of the tendons showed the experimental group had lesser adhesion and better reactiveness than that in the control group.the fibrin had degraded at 3 weeks. cell tracing showed that the labeled bone marrow derived mesenchymal stem cells remained viable and presented in the intratendinous region for at least 6 weeks, becoming more diffuse at later timepoints.at 3 weeks, collagen fibers appeared more organized and there were better morphometric nuclear parameters in the treatment group. at 6 and 12 weeks, there were no differences between the groups with regard to morphometric nuclear parameters.

结果］实验组相比对照组肌腱大体观察粘连差，肌腱活动性好。3周后纤维蛋白载体即降解，细胞示踪结果显示标记的骨髓间充质干细胞至少6周内仍可保持活性并存在于肌腱组织中，但之后逐渐扩散。3周时，实验组与对照组相比胶原纤维排列更为有序，且胞核形态结构更规则，但在6周及12周时，实验组与对照组胞核参数测定无统计学意义。3周时实验组比对照组具有更强的的生物力学特性，但之后则差别不明显。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
