[Abstract]  Human endometrial stem cell/stromal cells (hEnSCs) are isolated from endometrium or menstrual blood and are recognized as a valuable cell type in tissue engineering and cell therapy. Furthermore, hEnSCs, which have CD90 (a mesenchymal marker), CD105 (endoglin), CD44, CD146 (endometrial stem cell markers) and lack CD31 (Endothelial marker), CD34 (hematopoietic marker) and CD133 on the cell surface, are a new source of mesenchymal stem/stromal cells. Additionally, these cells can be encapsulated into self-assembling peptide nanofibers as a 3D scaffold for applications in the treatment of neurodegenerative diseases. Here, we describe a protocol to isolate hEnSCs from endometrium or menstrual blood. [摘要]  人类子宫内膜干细胞/基质细胞(hEnSCs)是从子宫内膜或经血中分离出来的,在组织工程和细胞治疗中被公认为有价值的细胞类型。 此外,在细胞表面具有CD90(间充质标记),CD105(内皮糖蛋白),CD44,CD146(子宫内膜干细胞标记)和缺乏CD31(内皮标记),CD34(造血标记)和CD133的hEnSCs是新的 间充质干细胞/基质细胞的来源。 此外,这些细胞可以封装成自组装肽纳米纤维作为三维支架应用于治疗神经退行性疾病。 在这里,我们描述了从子宫内膜或经血中分离hEnSC的方案。

【背景】正在研究细胞替代治疗,作为治疗神经退行性疾病(如阿尔茨海默病,中风和脊髓损伤)的新策略(Tavakol等人,2014b; 2015; 2016a和2016c)。子宫内膜干细胞/基质细胞(hEnSCs)可以从经血(Azedi等人,2014和2017)和子宫内膜分离。这些细胞具有脂肪形成(Khanmohammadi等人,2014),成骨(Darzi等人,2012)和软骨形成(Kazemnejad等人, >,2012)分化潜力。此外,这些细胞可以与支架组合用作组织工程应用中智能细胞支架的成分(Tavakol等人,2014a; 2016b和2017)。值得注意的是,诸如外来体,微泡和其他组分的细胞区室被认为比使用全细胞的治疗更安全。 ...

Bioelectrospray Methodology for Dissection of the Host-pathogen Interaction in Human Tuberculosis

[Abstract]  Standard cell culture models have been used to investigate disease pathology and to test new therapies for over fifty years. However, these model systems have often failed to mimic the changes occurring within three-dimensional (3-D) space where pathology occurs in vivo. To truthfully represent this, an emerging paradigm in biology is the importance of modelling disease in a physiologically relevant 3-D environment. One of the approaches for 3-D cell culture is bioelectrospray technology. This technique uses an alginate-based 3-D environment as an inert backbone within which mammalian cells and extracellular matrix can be incorporated. These alginate-based matrices produce highly reproducible results and can be mixed with different extracellular matrix components. This protocol ... [摘要]  标准细胞培养模型已被用于调查疾病病理学和测试新疗法超过五十年。 然而,这些模型系统通常未能模拟在体内发生病理学的三维(3-D)空间内发生的变化。 为了真实地表示这一点,生物学中新兴的范例是在生理相关的三维环境中建模疾病的重要性。 3-D细胞培养的方法之一是生物电喷雾技术。 该技术使用基于藻酸盐的3-D环境作为惰性骨架,其中可以并入哺乳动物细胞和细胞外基质。 这些基于藻酸盐的基质产生高度可重复的结果,并且可以与不同的细胞外基质组分混合。 该方案描述了一种结合分枝杆菌,原代人血液单核细胞和胶原 - 藻酸盐基质的3-D系统,以解剖结核病中宿主病原体的相互作用。
【背景】结核分枝杆菌(Mtb)是全球公共卫生重要性的病原体,每年造成180万人死亡,全球发病率达到1000万(世卫组织,2016年)。尽管在研究方面进行了大量投资,但需要更多地了解宿主 - 病原体的相互作用才能改善预防和治疗。目前,病原菌对常用药物的耐药性越来越高,出现广泛耐药Mtb。结核病(TB)领域的挑战之一是可用于询问宿主 - 病原体相互作用的模型系统,因为广泛使用的动物模型不能完全反映人类的病理学。因此,迫切需要通过开发与生理相关的体外环境(Bielecka等人,2017年; Tezera等人)来补充这些动物模型。,2017)。 ...

Primary Olfactory Ensheathing Cell Culture from Human Olfactory Mucosa Specimen

[Abstract]  The human olfactory mucosa is located in the middle and superior turbinates, and the septum of nasal cavity. Olfactory mucosa plays an important role in detection of odours and it is also the only nervous tissue that is exposed to the external environment. This property leads to easy access to the olfactory mucosa for achieving various researches. The lamina propria of olfactory mucosa consists of olfactory ensheathing cells (OECs) that cover the nerve fibers of olfactory. Here we describe a protocol for isolation of OECs from biopsy of human olfactory mucosa. [摘要]  人类嗅粘膜位于中鼻甲和鼻中隔,鼻腔隔膜。嗅粘膜在气味检测中起重要作用,也是暴露于外界环境的唯一神经组织。该属性可以方便地进入嗅粘膜进行各种研究。嗅粘膜固有层由覆盖嗅神经纤维的嗅鞘细胞(OEC)组成。在这里,我们描述了从人类嗅粘膜活检中分离OEC的方案。

背景 嗅鞘细胞(OECs)是神经胶质细胞,其表达与星形胶质细胞和施旺细胞类似的各种抗原,例如胶质纤维相关蛋白(GFAP),S100-β,p75低亲和力神经生长因子受体,波形蛋白,巢蛋白和神经肽Y (Singh等人,2013)。嗅鞘细胞释放在中枢神经系统的细胞生长和粘连中起作用的不同神经营养因子和粘附分子(Pastrana等人,2007)。此外,这些细胞在受损的中枢神经系统的再生中起重要作用,例如治疗脊髓损伤和神经变性疾病(Novikova等人,2011)。我们选择OEC作为我们研究中的研究材料,因为它们具有诸如高迁移能力,可及源,鼻嗅粘膜干细胞分化和非致瘤性行为等优势性质(Huang et al。 ,2008; Escada 等人,2009)。该方案描述了从人类嗅觉粘膜样品中分离OEC的一步一步的过程。
