We describe a case of flaccid paraparesis, intervening during treatment with simvastatin cyclosporine and low dose posaconazole, in a patient previously having undergone allogeneic hematopoietic transplantation. Final diagnosis was rhabdomyolysis related to statin. This is the first case reporting posaconazole as an agent favoring rhabdomyolysis when administered together with simvastatin and cyclosporine. In this patient, a low Vitamin D level may also have contributed to establishing rhabdomyolysis. Literature on rhabdomyolysis in transplanted patients is reviewed. Therapeutic choices in transplanted patients needing concomitant therapy with azole and statin are discussed.
我们描述了一个病例弛缓性截瘫,干预治疗期间与辛伐他汀环孢素和低剂量泊沙康唑,在病人之前接受了异体造血移植。最终诊断为横纹肌溶解与他汀类药物有关。这是第一个报道泊沙康唑与辛伐他汀和环孢素一起使用时有利于横纹肌溶解的病例。在本例患者中,低维生素D水平也可能导致横纹肌溶解。本文回顾了移植患者横纹肌溶解的文献。本文讨论了移植患者需要唑类和他汀类药物联合治疗的治疗选择。

Misoprostol is a synthetic prostaglandin E1 analogue used for a variety of indications in medical practice including medication of abortion.1 In addition to therapeutic usage, an unsupervised and illegal self-induction trend of Misoprostol administration has promoted its use as an illegal abortifacient.2 It is reported that 15% of misoprostol-induced-abortions may not be successful, even under medical supervision. This leads to in utero exposure of the drug to the developing fetus.3 It is scientifically claimed that use of misoprostol with failure to abort may be linked to birth defects suggesting an 8-10% risk of abnormalities among women who use misoprostol and experience abortion failure.4

Parkinson’s disease (PD) is a neurodegenerative disease which is caused by many factors including progressive degeneration of dopamine (DA)-secreting neurons which reside in the midbrain substantia nigra compacta (SNc). Current available treatments comprise of intake of DA replenishing drugs or implantation of electrical impulse device. However, the short-term effect of the treatments and risks of side effects haveseverely limited the widespread application of thesetherapiesfor all patients with PD.Hence, human embryonic stem cells (hESCs), which are capable of both self renewal and differentiation into all cell types of human body, could potentially provide a renewable source of surrogate DA neurons for transplantation into PD patients. One of the challenges in using hESCs therapeutically is the establishment of protocols that could effectively direct their differentiation into functionalDA neurons. A specific investigation on the derivation of DA neurons was carried out by usinga three-dimensional (3D)environmentsuch as encapsulation. Characterizationstudyby microarray wasperformed to analyze the global expression profile in 3D-derived DA neurons after 28 days of differentiation. In comparison to the samples of DA neuronal differentiated hESCs under 2D platform for 28 days, the analysis detected the reduced expression of gene that are involved in pluripotency or mitosis but increased expression of genes that are involved in neuronal developments such as Wnt, hedgehogand mitogen-activated protein kinase (MAPK) signaling pathway. The results suggest that the 3D differentiation system may have affected the regulatory or signalling mechanisms which enhanced the rate of differentiation towards ectoderm.
帕金森病(PD)是一种由多种因素引起的神经退行性疾病,包括位于中脑黑质致密体(SNc)的分泌多巴胺(DA)的神经元进行性变性。目前可用的治疗方法包括服用DA补充药物或植入电脉冲装置。然而,治疗的短期效果和副作用的风险严重限制了这些治疗在所有PD患者中的广泛应用。因此,人类胚胎干细胞(hESCs)具有自我更新和分化为人体所有细胞类型的能力,可能为PD患者移植提供替代DA神经元的可再生来源。利用hESCs进行治疗的挑战之一是建立能够有效引导其分化为功能性da神经元的方案。利用三维(3D)环境(如封装)对DA神经元的衍生进行了具体研究。通过微阵列进行表征研究,分析分化28天后3d来源的DA神经元的全局表达谱。与2D平台下28天的DA神经元分化hESCs样品相比,分析发现多能性或有丝分裂相关基因表达减少,而Wnt、hedgehog和丝裂原活化蛋白激酶(MAPK)信号通路等神经元发育相关基因表达增加。结果表明,三维分化系统可能影响了调控或信号机制,从而提高了向外胚层分化的速度。

Endometrium is a dynamic organ, which undergoes extensive proliferation and regeneration throughout reproductive cycle of women. Hence, extensive research on adult stem cells of endometrium is underway. An easy approach to identify stem cells is its marker characterization. However, does these markers behave same in all conditions of stem cells in-vitro is uncertain? Hence, the main objective of the study is to check if mesenchymal stem cells of the endometrium (eMSCs) could retain its marker characterization at various passages in-vitro.   The study design was accomplished as follows: The endometrial tissue (n=10) were collected from reproductively active women with a mean age of 35±1.5 and body mass index of 24±1.4, undergoing D&C/hysterectomy. Samples were collected in a sterile manner. The plastic, adherent mesenchymal stem cells obtained from culturing of the cells isolated from endometrial tissue (eMSCs) are characterized for study design was accomplished by characterizing some of the markers such as CD44, CD166, CD106, CD49d, CD31, CD54, CD34, CD117, CD90, CD105, CD73, CD140b, ABCG2 of eMSCs at various passages (P1, P3, P5 & P10) in-vitro using flowcytometry. The obtained results were analysed statistically using student’s t-test and significant results are discussed. The study identified tissue-specific markers of eMSCs, where the percentage expression of most of the markers was consistently similar at P3 and P10, expect for CD49d and CD54, which showed a reduction pattern and ABCG2, which showed an increase in percentage at P10 as compared to P3. This article reveals the significance of in-depth marker characterization of human endometrial stem cells in-vitro.
子宫内膜是一个动态的器官,在女性的整个生殖周期中经历着广泛的增殖和再生。因此,对子宫内膜成体干细胞的广泛研究正在进行中。鉴别干细胞的一个简单方法是它的标记特征。然而,这些标记是否在体外干细胞的所有条件下表现相同是不确定的?因此,本研究的主要目的是检查子宫内膜间充质干细胞(eMSCs)是否能在体外不同传代中保持其标志物特征。研究设计如下:选取平均年龄35±1.5岁、体重指数24±1.4、行D&C/子宫切除术的育龄妇女子宫内膜组织(n=10)。样品以无菌方式采集。从子宫内膜组织(eMSCs)分离的细胞培养中获得的可塑,粘附的间充质干细胞被表征为研究设计,通过使用流式细胞术表征eMSCs在不同传代(P1, P3, P5和P10)的一些标记物,如CD44, CD166, CD106, CD49d, CD31, CD54, CD34, CD117, CD90, CD105, CD73, CD140b, ABCG2完成。所得结果采用学生t检验进行统计分析,并对显著性结果进行讨论。本研究确定了eMSCs的组织特异性标记物,其中大多数标记物在P3和P10的表达百分比一致,除了CD49d和CD54在P10表现出减少模式,ABCG2在P10表现出与P3相比的百分比增加。本文揭示了人子宫内膜干细胞体外深度标志物表征的意义。

Stem cell treatment after ischemic stroke alters the expression of dna damage signaling molecules 缺血性中风后的干细胞治疗改变了dna损伤信号分子的表达

Accumulating evidence suggests that oxidative DNA damage plays a critical role in cell death associated with ischemic stroke. Endogenous oxidative DNA damage can be detected in the ischemic brain during the stages that precedes the manifestation of cell death and is believed to trigger cell death via various intracellular signaling pathways. Inhibiting the signaling associated with DNA damage induction or facilitating the signaling associated with the DNA repair process can be neuroprotective against brain injury after ischemic stroke. Recent reports demonstrated that human umbilical cord blood-derived mesenchymal stem cells (HUCB-MSCs) prevented the upregulation of apoptotic signaling pathway molecules and thereby attenuated the extent of apoptosis after focal cerebral ischemia as well as improved the neurological recovery. Therefore, we hypothesized that HUCB-MSCs treatment after focal cerebral ischemia prevents the overexpression of molecules associated with DNA damage induction as well as augments the expression of molecules associated with DNA repair process. In order to test our hypothesis, we administered HUCB-MSCs (0.25x106cells/animal) intravenously via tail vein to male Sprague-Dawley rats that were subjected to a two-hour middle cerebral artery occlusion followed by one-day reperfusion. Ischemic brain tissues obtained from various groups seven days’ post reperfusion were subjected to DNA damage signaling pathway PCR microarray. Our results demonstrated the induction of both DNA damage inducing and repair genes after focal cerebral ischemia and reperfusion. HUCB-MSCs treatment downregulated the DNA damage inducing genes and upregulated the DNA repair genes without disturbing the endogenous defense mechanisms.
越来越多的证据表明,氧化性DNA损伤在缺血性中风相关的细胞死亡中起关键作用。内源性氧化DNA损伤可以在缺血脑细胞死亡前的阶段检测到,并被认为通过各种细胞内信号通路触发细胞死亡。抑制与DNA损伤诱导相关的信号传导或促进与DNA修复过程相关的信号传导可能对缺血性脑卒中后脑损伤具有神经保护作用。最近的报道表明,人脐血源性间充质干细胞(HUCB-MSCs)可以阻止凋亡信号通路分子的上调,从而减轻局灶性脑缺血后的细胞凋亡程度,并改善神经系统的恢复。因此,我们假设局灶性脑缺血后hub - mscs治疗可以阻止与DNA损伤诱导相关分子的过表达,并增强与DNA修复过程相关分子的表达。为了验证我们的假设,我们通过尾静脉给雄性Sprague-Dawley大鼠注射hub - mscs (0.25x106个细胞/只),这些大鼠被阻断大脑中动脉2小时,然后再灌注1天。取各组再灌注后7 d的缺血脑组织进行DNA损伤信号通路PCR芯片检测。我们的研究结果表明,局灶性脑缺血再灌注后,DNA损伤诱导基因和修复基因都被诱导。hub - mscs处理在不干扰内源性防御机制的情况下,下调了DNA损伤诱导基因,上调了DNA修复基因。

The focus on Stem cells provides a considerable attention in translational medicine for their potential capacity in terms of tissue regeneration, repair and as drug delivery. Recent evidences showed that stem cells secrete small vesicles into the extracellular milieu, known as extracellular vesicles (EVs). They are known to carry a repertoire of mRNAs, miRNAs, DNA, proteins, and lipids that can be transferred to neighboring cells, modifying their phenotype as well as the microenvironment. Stem cell-Extracellular vesicles may provide the opportunity to overcome the hurdles or complications raised in stem cell therapeutic strategies. Our data showed that the extracellular vesicles secreted by the spheroids, constituted by the stem cells obtained by the dedifferentiation process are positive for CD133 and negative for the multi-drug resistance and tumorigenecity.
干细胞在组织再生、修复和药物传递方面的潜在能力,为转化医学提供了相当大的关注。最近的证据表明,干细胞分泌小泡进入细胞外环境,称为细胞外囊泡(EVs)。众所周知,它们携带一系列mrna、mirna、DNA、蛋白质和脂质,可以转移到邻近细胞,改变其表型和微环境。干细胞-细胞外囊泡可能为克服干细胞治疗策略中的障碍或并发症提供机会。我们的数据表明,由去分化过程获得的干细胞组成的球体分泌的细胞外囊泡对CD133呈阳性,对多药耐药和致瘤性呈阴性。

Stem cell-Extracellular vesicles may provide the opportunity to overcome the hurdles or complications raised in stem cell therapeutic strategies. Our data showed that the extracellular vesicles secreted by the spheroids, constituted by the stem cells obtained by the dedifferentiation process are positive for CD133 and negative for the multi-drug resistance and tumorigenecity.","PeriodicalId":91560,"journal":{"name":"Journal of stem cell research & therapeutics","volume":"289 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77743196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stem cells are undifferentiated cells classified into two groups, a) stem cells from embryos formed during the blastocyst phase of an embryological development and b) stem cells of an adult. Embryonic stem cells are derived from a 4-5 day old human embryo that is in the blastocyst phase of a development [1]. Adult stem cells exist throughout the body after embryonic development and are found inside of different types of tissues. Adult bone marrow and fat have stem cells along with other tissues [2]. Apart from these two types there is also embryonic germ cells which are collected from the fetus later in developmental process from gonadal ridge [3]. Adult stem cell serve as fresh source of cells in living organism They replace the cells that need to be replaced on regular basis like blood and other connective tissue [4]. Stem cell technology is rapidly growing in the field of regenerative medicine [5]. According to Patil AM, stem cell research has offered a new viable therapeutic option for degenerative diseases, injuries and other diseased condition. Stem cells are called as master cells with ability to grow into more than 200 cell types [6,7]. Based on their capacity to divide and differentiate they may be totipotent, pluripotent or multipotent [5].
干细胞是未分化的细胞,分为两类:a)胚胎发育的囊胚期形成的胚胎干细胞和b)成人的干细胞。胚胎干细胞来源于4-5天大的处于发育阶段的囊胚期的人类胚胎。成体干细胞存在于胚胎发育后的全身,存在于不同类型的组织中。成人骨髓和脂肪中含有干细胞以及其他组织。除了这两种类型之外,还有胚胎生殖细胞,这些细胞是从发育后期的胎儿性腺脊区收集的。成体干细胞是生物体中新鲜的细胞来源,它们替代了像血液和其他结缔组织一样需要定期替换的细胞。干细胞技术在再生医学领域正迅速发展。根据Patil AM的说法,干细胞研究为退行性疾病、损伤和其他疾病提供了一种新的可行的治疗选择。干细胞被称为主细胞,能够生长成200多种细胞类型[6,7]。根据它们的分裂和分化能力,它们可以是全能性、多能性或多能性bbb。
