[Abstract]  Asthma is a global problem that affects millions of individuals. An increased risk of respiratory viral and bacterial infections is one of the complications of asthma. We recently reported that mice with ovalbumin-induced allergic airway disease (AAD) are protected against influenza-Streptococcus pneumoniae co-infection. Here, we describe in detail a protocol on how to induce AAD and influenza-S. pneumoniae co-infection in mice and to evaluate the specific roles of asthma on immunity to viral and bacterial pathogens in the hope of translating findings to benefit asthmatic individuals. [摘要]  [摘要] 哮喘是一个全球性问题,影响着数以百万计的人。呼吸道病毒和细菌感染的风险增加是哮喘的并发症之一。我们最近报道说,患有卵白蛋白诱发的过敏性气道疾病(AAD)的小鼠可以预防流行性感冒肺炎链球菌合并感染。在这里,我们详细描述议定书中关于如何诱导AAD和流行性感冒肺炎链球菌合并感染的小鼠并要评估的具体作用哮喘在抗干扰性病毒和细菌病原体的希望翻译发现以使哮喘患者受益。

[背景] 全球患病个体与哮喘的增加,随着300亿目前的痛苦和额外的100万个新发生率预测到2025年(生菜等,2017) 。由于中改变的免疫系统,哮喘的个体被认为具有风险增加易感性的流感感染的季节性和大流行性流感感染可导致并发Bacteri 铝感染可导致气道呼吸窘迫综合征,潜在的危及生命的疾病(Gilca 等,2011) 。无论是否哮喘病是在最近的2009年H1N1大流行期间,哮喘患者更容易因流感住院,但临床数据也表明哮喘患者死亡或需要ICU的可能性较小与没有哮喘的人相比,流感大流行期间大多数死亡不是由每次入院的病毒感染引起的。本身,但实际上是由于继发细菌感染引起的并发症(Morens 等人,2008; MacIntyre 等人,2018)。我们先前曾报道患有AAD的小鼠对流感病毒或肺炎链球菌的单次感染具有抗性(Furuya 等人,2015; Sanfilippo ...

[Abstract]  The discovery of endothelial colony forming cells (ECFCs) with robust self-renewal and de novo vessel formation potentials suggests that ECFCs can be an excellent cell source for cardiovascular diseases treatment through improving neovascularization in the ischemic tissues. However, their engraftment after transplantation resulted to be low. Previous studies showed mesenchymal stem/stromal cells (MSCs) could improve the survival and capillary formation capacity of ECFCs in co-culture systems. In this article, we describe a protocol for in vitro co-culture of MSCs and ECFCs to prime ECFCs for better engraftment. [摘要]  发现具有强大自我更新和从头血管形成潜力的内皮细胞集落形成细胞(ECFCs)表明,ECFC可以通过改善缺血组织的新生血管形成,成为心血管疾病治疗的优良细胞来源。 然而,移植后的移植导致了低位移植。 以前的研究显示间充质干/基质细胞(MSC)可以改善共培养系统中ECFCs的存活和毛细管形成能力。 在这篇文章中,我们描述了体外协调MSCs和ECFCs共同培养ECFC以实现更好的移植。
【背景】内皮祖细胞(EPC)被定义为能够通过血管发生过程形成新血管的细胞群。 2004年,Ingram等人鉴定了来自人脐带血的称为“内皮细胞集落形成细胞(ECFC)”的离体培养物中的特异性高度增殖的EPC群体Ingram等人,2004),并且这些细胞最近被宣布代表EPCs(Medina等人,2017)。类似的群体也可以从具有等效血管化潜力和临床相关数量的人类胎盘组织中分离(Patel等人,2013; Shafiee等人,2015) )。因此,ECFC移植已被提出作为缺血性疾病如心肌梗塞或关键性腿部缺血的治疗方法。然而,移植后的ECFCs植入物和血管生成潜力被证明是低的(Shafiee等人,2017; ...

Isolation and Primary Culture of Adult Human Adipose-derived Stromal/Stem Cells

[Abstract]  Adipose-derived stromal/stem cells (ASCs) are multipotent cells that can be isolated from adipose tissue. Studies have shown that cells have the capacity to self-renew and differentiate into adipocyte, chondrocyte, myocyte, and osteoblast lineages. Thus, significant interest regarding their use for regenerative purposes to restore aging or damaged tissue has grown in recent decades. These cells have also been shown to immunomodulate the microenvironment and secrete abundant growth factors, which minimize inflammation and aid repair and regeneration. ASCs can be readily isolated from the stromal vascular fraction (SVF) of lipoaspirates. Given their ease of accessibility, bountiful source, and potential application in regenerative medicine and tissue engineering, there is growing interest ... [摘要]  脂肪来源的基质/干细胞(ASCs)是可以从脂肪组织分离的多能细胞。研究表明,细胞具有自我更新和分化成脂肪细胞,软骨细胞,肌细胞和成骨细胞谱系的能力。因此,近几十年来,对再生用途恢复老化或损伤组织的兴趣越来越大。这些细胞也被证明可以免疫微环境并分泌丰富的生长因子,从而使炎症最小化并辅助修复和再生。 ASCs可以容易地从脂质体的基质血管分数(SVF)中分离出来。鉴于其易于获取,丰富的来源和在再生医学和组织工程中的潜在应用,对于ASC的表征和利用越来越感兴趣。该方案描述了从成人人类脂肪组织中分离的ASC以及用于培养维持的方法,包括扩增和低温保存。

背景 脂肪来源的基质/干细胞(ASCs)表现出干细胞领域的巨大潜力。根据造血干细胞移植的治疗奇迹,ASCs代表干细胞的未来,因为它们更容易获得源 - 脂肪组织。 ASCs自我更新和分化成各种组织谱系(包括脂肪细胞,软骨细胞,肌细胞和成骨细胞谱系)的能力允许恢复损伤的组织。另外,推测ASCs有可能在体外复制组织。器官将允许更容易获得新颖药物的评估,从而显着降低药物生产成本。然而,隔离,维护和冷冻保存过程中的不一致,禁止集体分析世界各地不同实验室的结果。用于分离和培养ASC的标准方案对于确保一致的数据分析是必要的。
