[Abstract]  During the course of evolution, prokaryote and eukaryote cells have developed elegant and to some extent analogous strategies to communicate with each other and to adapt to their surrounding environment. Eukaryotic cells communicate with each other through direct interaction via juxtracrine signaling and/or by secreting soluble factors. These secreted factors can subsequently act on the cell itself (autocrine signaling) or interact with neighboring (paracrine signaling) and distant (endocrine signaling) cells. The transmission of signals between cells and tissues has been traditionally ... [摘要]  在进化过程中,原核生物和真核生物细胞已经形成了优雅,在一定程度上类似的相互交流和适应周围环境的策略。真核生物细胞通过直接相互作用经Juxtracrine信号传导和/或通过分泌可溶性因子相互沟通。这些分泌的因子随后可以作用于细胞本身(自分泌信号传导)或与邻近的(旁分泌信号传导)和远处的(内分泌信号传导)细胞相互作用。传统上认为细胞和组织之间的信号传递受到基于蛋白质的信号传导系统的调节。通常,通过胞吐作用分泌到细胞外环境中的蛋白质含有典型的分泌靶向序列(Théry等,2002)。然而,具有非连续和刺激依赖性分泌的蛋白质,不含有经典分泌靶向序列的蛋白质,以及在细胞外环境(DNA,mRNA,肽,代谢物,miRNA和其他RNA)中可能过于不稳定的物质物种)可以以特定的方式分泌在小膜胞外囊泡(EV)中(Hagiwara等人,2014)。外来体代表直径为30-130nm的这些分泌的膜囊泡中的一大类(Cocucci等人,2009;Théry等人,2009; Kowal等人, >,et al。,2014),其形成在称为多泡体的内体隔室中的分泌细胞内。加载到外泌体中的分子以及细胞之间外来体转移的强度是随后调节受体细胞的重要参数。目前关于外泌体分泌及其在受体细胞中内化的知识仍不完整。已知外泌体的分泌强度根据细胞类型和其生理状态而变化(Garcia等人,2016)。此外,促进与细胞 - ...

[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 ... [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; ...

[Abstract]  Circulating endothelial progenitor cells (EPCs) have been the focus of many clinical trials due to their roles in revascularisation following ischemic events such as acute myocardial infarction as well as their contribution to vascular repair during organ transplantation. Research on EPCs has been controversial due to the lack of distinct markers expressed at the cell surface and varying methods for isolation and culture have resulted in the identification of a multitude of cell types, with differing phenotype and function, all falling under the label of “EPCs”. The most widely documented ... [摘要]  循环内皮祖细胞(EPCs)已经成为许多临床试验的焦点,因为它们在缺血事件例如急性心肌梗死后的血管再形成中的作用以及它们在器官移植期间对血管修复的贡献。由于缺乏在细胞表面表达的不同标记物,EPCs的研究已经引起争议,并且用于分离和培养的不同方法导致鉴定了具有不同表型和功能的多种细胞类型,所有这些都属于" EPCs"。分离用于细胞治疗的最广泛记载的EPCs本质上是粘附的,缺乏祖细胞标志物例如CD133,因此不太可能代表真正的循环EPC,所述细胞响应于血管损伤而动员。
我们最近发布了非粘附内皮形成细胞(naEFCs)群体的分离和广泛表征(Appleby等人,2012)(图1)。这些细胞与成熟内皮细胞标记(VEGFR2,CD144和CD31)一起表达祖细胞标记(CD133,CD34,CD117,CD90和CD38)。这些细胞还表达低水平的CD45,但不表达将其与"早期"EPC区分开的淋巴标志物(CD3,CD4,CD8)或骨髓标志物(CD11b和CD14),"晚期生长EPC"[最近称为内皮细胞集落形成细胞(ECFCs)]以及成熟内皮细胞(ECs)。图2A例示了naEFC的表面表达谱。功能研究证明这些naEFC(i)结合于玻璃体凝集素(图2A),(ii)显示乙酰化低密度脂蛋白摄取,(iii)增加血管细胞粘附分子(VCAM-1)响应于肿瘤坏死因子的表达和(iv)与成熟EC的共培养增加了在三维体外基质中的管,小管分支和环的数目。更重要的是,放置在体内的naEFC产生了包含由表达CD144的人EC内衬的脉管系统的新腔,并且有助于科学知识的各种进步(Appleby等人,2012; ...
