[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。

[Abstract]  Glioblastoma multiforme (GBM) is a grade 4 astrocytoma tumor in central nervous system. Astrocytes can be isolated from human GBM. Study of astrocytes can provide insights about the formation, progression and recurrence of glioblastoma. For using isolated astrocytes, new studies can be designed in the fields of pharmacology, neuroscience and neurosurgery for glioblastoma treatment. This protocol describes the details for preparing high purity primary astrocytes from human GBM. Tumor tissue is disrupted using mechanical dissociation and chemical digestion in this protocol. 2 weeks after plating the cell suspension in culture, primary astrocytes are available for further subculturing and immunocytochemistry of S100-beta antigen. [摘要]  多形性葡萄球菌(GBM)是中枢神经系统中的4级星形细胞瘤。星形胶质细胞可以从人类GBM中分离出来。研究星形胶质细胞可以提供关于胶质母细胞瘤的形成,进展和复发的见解。对于使用孤立的星形胶质细胞,可以在药理学,神经科学和神经外科学领域设计新的研究用于成胶质细胞瘤治疗。该方案描述了从人类GBM制备高纯度原发性星形胶质细胞的细节。在本方案中使用机械解离和化学消化破坏肿瘤组织。培养细胞悬液2周后,初级星形胶质细胞可用于S100-β抗原的进一步传代培养和免疫细胞化学。

星形胶质细胞是提供脑神经元结构和营养支持的神经胶质细胞。星形胶质细胞的细胞周期似乎在星形细胞瘤脑肿瘤中被破坏。世界卫生组织根据恶性肿瘤将星形细胞分为四级。多形性成胶质细胞瘤(GBM,IV级)是星形细胞瘤最恶性的形式。成胶质细胞瘤的特征在于具有快速增殖速率和血管生成的侵袭性细胞。胶质母细胞瘤患者预后差。目前的治疗方法,包括手术,化学治疗和放射治疗对患者的治疗没有很好的疗效。患者的中位生存时间大约在治疗后一年(Stuup等人,2005; Wen和Kesari,2008)。许多研究人员专注于评估胶质母细胞瘤细胞的生理功能和凋亡的研究,以便检测更有效的治疗方法。在这里,我们提出了一种从没有成纤维细胞污染的人胶质母细胞瘤标本中分离高纯度原代星形胶质细胞的方法(Hashemi等人,2016)。
