[Abstract]  

Current methods to obtain mesenchymal stem cells (MSCs) involve sampling, culturing, and expanding of primary MSCs from adipose, bone marrow, and umbilical cord tissues. However, the drawbacks are the limited numbers of total cells in MSC pools, and their decaying stemness during in vitro expansion. As an alternative resource, recent ceiling culture methods allow the generation of dedifferentiated fat cells (DFATs) from mature adipocytes. Nevertheless, this process of spontaneous dedifferentiation of mature adipocytes is laborious and time-consuming. This paper describes a modified protocol for in vitro dedifferentiation of adipocytes by employing an additional physical stimulation, which takes advantage of augmenting the stemness-related Wnt/β-catenin signaling. Specifically, this

[摘要]  [摘要]目前的方法,以获得间充质干细胞(MSC)包括采样,培养,和扩大主要由脂肪,骨髓,和脐带组织的MSCs。然而,缺点是在总细胞在MSC池,和它们的衰减干性的数量有限在维生素- [R Ò扩张。作为替代资源,最近的天花板培养方法允许从成熟的脂肪细胞中生成去分化的脂肪细胞(DFAT)。然而,这种成熟脂肪细胞自发去分化的过程既费力又费时。本文描述了一种用于经修改协议在体外通过采用附加的物理刺激,其中脂肪细胞去分化TA KES扩充所述干性相关的优点的Wnt /β-catenin信号。具体来说,该协议利用含聚乙二醇(PEG)的高渗介质引入细胞外物理刺激以获得更高的效率,并引入更简单的脂肪细胞去分化程序。


[背景]脂肪组织由于其丰度大且侵袭性相对较低,因此是间充质干细胞(MSC)最具吸引力的来源之一(Shen等,2011 ;González-Cruz等,2012; Konno等人,2013)。脂肪来源的MSC,即从皮下脂肪组织的基质血管级分中分离,已被证实同时显示多谱系潜能的体外和体内(Anghileri等人,2008;冈萨雷斯。等人,2009;冈萨雷斯-雷伊等等人,2010; Jumabay等人,2010; Mao等人,2017和2019 ;Darnell等人,2018 ...

Immunohistochemistry of Kidney a-SMA, Collagen 1, and Collagen 3, in A Novel Mouse Model of Reno-cardiac Syndrome

[Abstract]  Cardiorenal syndrome defines a synergistic pathology of the heart and kidneys where failure of one organ causes failure in the other. The incidence of cardiovascular mortality caused by this syndrome, is 20 fold higher in the end stage renal disease (ESRD) population compared to the population as a whole thus necessitating the need for improved therapeutic strategies to combat reno-cardiac pathologies.

Murine in vivo models play a major role in such research permitting precise genetic modification thus reducing miscellany, however presently there is no steadfast model of reno-cardiac syndrome in the most common genetically modified mouse strain, the C57BL/6 mouse. In this study we have modified an established model of chronic renal disease using adenine diet and ...
[摘要]  [摘要 ] 心肾综合征定义了心脏和肾脏的协同病理,其中一个器官的衰竭导致另一个器官的衰竭。与整个人群相比,该综合征导致的心血管疾病死亡率在终末期肾脏病(ESRD)人群中要高出20倍,因此有必要改善治疗策略以应对肾病。

小鼠体内模型在允许精确基因修饰从而减少杂项的研究中起主要作用,但是目前在最常见的基因修饰小鼠品系C57BL / 6小鼠中还没有稳定的雷诺-心脏综合征模型。在这项研究中,我们使用腺嘌呤饮食修改了已建立的慢性肾脏疾病模型,并扩展了在C57BL / 6小鼠中实现慢性肾功能衰竭和随之而来的肾心脏综合征的相关病理。

使八周大的雄性C57BL / 6小鼠适应7天,然后给予0.15%腺嘌呤饮食或对照饮食20周,此后终止实验,收集血液,尿液和器官并进行生化和免疫组织化学分析。

施用0.15%的腺嘌呤饮食会导致进行性肾功能衰竭,从而导致肾性心脏病综合征,这可通过心体重比显着增加来证实(P <0.0001)。血液生化表明,用腺嘌呤喂养的小鼠血清肌酐,尿素含量显着增加(P <0.0001),肾小球滤过率显着降低(P <0.05),而肾脏的α-SMA,胶原蛋白1和胶原蛋白3免疫组化显示严重的纤维化。

我们提出了一种新型的腺嘌呤饮食方案,该方案在C57BL / ...

[Abstract]  Our protocol describes immunofluorescent staining, hematoxylin and eosin staining and Masson’s trichrome staining on lung sections. [摘要]  我们的方案描述了免疫荧光染色,苏木精和伊红染色以及Masson在肺切片上的三色染色。

背景 肺的主要功能是气体交换。肺由各种专门的细胞和组织组成,包括支气管,细支气管和肺泡,以促进气体交换。为了研究小鼠模型中的肺发育或肺部疾病,可以从小鼠中去除肺,并将其冷冻并嵌入最佳切割温度(OCT)化合物或化学保藏并包埋在石蜡中。为了保持肺组织结构,我们用1ml OCT化合物填充肺,用于制备冷冻切片,或用于石蜡切片的10%缓冲福尔马林(Zhou等人,2016)。然后将肺切片从冷冻或石蜡包埋的肺切片并安装到载玻片上用于制备染色。我们使用冷冻组织切片进行基于抗体的免疫荧光染色,并使用石蜡包埋切片进行苏木精和伊红(H&E)染色或Masson三色染色。冷冻切片更快地准备免疫荧光染色,大多数抗体在冷冻切片上工作良好。石蜡切片也可用于免疫荧光染色,但需要脱蜡,补液和抗原检索。即使在抗原检索后,一些抗体在石蜡切片上也不能很好地工作。然而,石蜡样品可以在室温下储存很长时间,并且可以容易地切成非常薄的部分。石蜡切片保留比冷冻切片更好的组织形态,因此它们对于H&E或三色染色更好。
