Long-Term in vivo Evaluation of Orthotypical and Heterotypical Bioengineered Human Corneas.

2020

Purpose: Human cornea substitutes generated by tissue engineering currently require limbal stem cells for the generation of orthotypical epithelial cell cultures. We recently reported that bioengineered corneas can be fabricated in vitro from a heterotypical source obtained from Wharton’s jelly in the human umbilical cord (HWJSC). Methods: Here, we generated a partial thickness cornea model based on plastic compression nanostructured fibrin-agarose biomaterials with cornea epithelial cells on top, as an orthotypical model (HOC), or with HWJSC, as a heterotypical model (HHC), and determined their potential in vivo usefulness by implantation in an animal model. Results: No major side effects …

Human Mesenchymal Stem Cells Prevent Neurological Complications of Radiotherapy

2019

Radiotherapy is a highly effective tool for the treatment of brain cancer. However, radiation also causes detrimental effects in the healthy tissue, leading to neurocognitive sequelae that compromise the quality of life of brain cancer patients. Despite the recognition of this serious complication, no satisfactory solutions exist at present. Here we investigated the effects of intranasal administration of human mesenchymal stem cells (hMSCs) as a neuroprotective strategy for cranial radiation in mice. Our results demonstrated that intranasally delivered hMSCs promote radiation-induced brain injury repair, improving neurological function. This intervention confers protection against inflamma…

Estudio de la quiescencia y activación de las células madre neurales adultas por uniones adherentes: papel de la N-cadherina.

2017

El descubrimiento de poblaciones de células madre en el cerebro adulto (NSCs) de los mamíferos ha cambiado nuestra visión del sistema nervioso, añadiendo el concepto de plasticidad celular al de plasticidad neural. El conocimiento detallado de los mecanismos que permiten a las NSCs mantenerse indiferenciadas, dividirse de manera asimétrica para auto-perpetuarse mientras generan progenie diferenciada, y activarse para proliferar contribuyendo así a la renovación de ciertas poblaciones de neuronas durante toda la vida se ha convertido en un campo de investigación en continuo avance. El desarrollo de técnicas que permiten la posibilidad de expandir las NSCs in vitro y de estudiarlas en su micr…

Pharmacological activation of CB2 receptors counteracts the deleterious effect of ethanol on cell proliferation in the main neurogenic zones of the a…

2015

Chronic alcohol exposure reduces endocannabinoid activity and disrupts adult neurogenesis in rodents, which results in structural and functional alterations. Cannabinoid receptor agonists promote adult neural progenitor cell (NPC) proliferation. We evaluated the protective effects of the selective CB1 receptor agonist ACEA, the selective CB2 receptor agonist JWH133 and the fatty-acid amide-hydrolase (FAAH) inhibitor URB597, which enhances endocannabinoid receptor activity, on NPC proliferation in rats with forced consumption of ethanol (10%) or sucrose liquid diets for 2 weeks. We performed immunohistochemical and stereological analyses of cells expressing the mitotic phosphorylation of his…

2012

Entre las diversas afecciones que pueden causar infertilidad, la baja calidad gamética juega un importante papel. El estudio del desarrollo de la línea germinal es, por tanto, necesario para comprender las causas de la mala calidad gamética y así ayudar a mejorarla. Sin embargo, nuestro conocimiento actual acerca del desarrollo de la línea germinal in vivo en humanos es limitado, debido en gran parte a las limitaciones éticas y técnicas para obtener embriones humanos en estadíos tempranos del desarrollo. En este sentido, las células madre embrionarias humanas (hESCs, del inglés human Embryonic Stem Cells) y las células madre de pluripotencia inducida (iPSCs, del inglés induced Pluripotent S…

Extracellular vesicles do not mediate the anti-inflammatory actions of mouse-derived adipose tissue mesenchymal stem cells secretome

2021

Este artículo se encuentra disponible en la siguiente URL: https://www.mdpi.com/1422-0067/22/3/1375 Este artículo pertenece al número especial "The Role of Mesenchymal Stem Cells on Inflammatory and Fibrotic Diseases". Adipose tissue represents an abundant source of mesenchymal stem cells (MSC) for therapeutic purposes. Previous studies have demonstrated the anti-inflammatory potential of adipose tissue-derived MSC (ASC). Extracellular vesicles (EV) present in the conditioned medium (CM) have been shown to mediate the cytoprotective effects of human ASC secretome. Nevertheless, the role of EV in the anti-inflammatory effects of mouse-derived ASC is not known. The current study has investiga…

The Genotype of the Donor for the (GT)n Polymorphism in the Promoter/Enhancer of FOXP3 Is Associated with the Development of Severe Acute GVHD but Do…

2015

The FOXP3 gene encodes for a protein (Foxp3) involved in the development and functional activity of regulatory T cells (CD4+/CD25+/Foxp3+), which exert regulatory and suppressive roles over the immune system. After allogeneic stem cell transplantation, regulatory T cells are known to mitigate graft versus host disease while probably maintaining a graft versus leukemia effect. Short alleles (<=(GT)(15)) for the (GT)(n) polymorphism in the promoter/enhancer of FOXP3 are associated with a higher expression of FOXP3, and hypothetically with an increase of regulatory T cell activity. This polymorphism has been related to the development of auto-or alloimmune conditions including type 1 diabetes …

Umbilical cord blood transplantation from unrelated donors in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia

2014

Clinical Trial; Journal Article; Research Support, Non-U.S. Gov't; There are very few disease-specific studies focusing on outcomes of umbilical cord blood transplantation for Philadelphia chromosome-positive acute lymphoblastic leukemia. We report the outcome of 45 patients with Philadelphia chromosome-positive acute lymphoblastic leukemia who underwent myeloablative single unit cord blood transplantation from unrelated donors within the GETH/GITMO cooperative group. Conditioning regimens were based on combinations of thiotepa, busulfan, cyclophospamide or fludarabine, and antithymocyte globulin. At the time of transplantation, 35 patients (78%) were in first complete remission, four (8%) …

Bioactivity of bioceramic materials used in the dentin-pulp complex therapy : a systematic review

2019

Este es el artículo que se ha publicado de forma definitiva en: https://www.mdpi.com/1996-1944/12/7/1015 Dentistry-applied bioceramic materials are ceramic materials that are categorized asbioinert, bioactive and biodegradable. They share a common characteristic of being specificallydesigned to fulfil their function; they are able to act as root canal sealers, cements, root repair or fillingmaterials. Bioactivity is only attributed to those materials which are capable of inducing a desiredtissue response from the host. The aim of this study is to present a systematic review of availableliterature investigating bioactivity of dentistry-applied bioceramic materials towards dental pulp stemcel…

Estructura nuclear y quiescencia en células madre neurales

2017

La zona subventricular-ventricular (ZSV-V) es un extenso nicho neurogénico que contiene células madre neurales (astrocitos B) en las paredes de los ventrículos laterales del cerebro adulto de mamíferos. Las células del subtipo B1 han sido identificadas clásicamente como las verdaderas células madre, tienen un origen embrionario y se mantienen quiescentes hasta que se reactivan post-natalmente. En el presente estudio, mostramos que una subpoblación de células B de la ZSV-V presenta una estructura nuclear denominada “lámina de cromatina de la envoltura nuclear” (ELCS, del inglés envelope-limited chromatin sheets), previamente descrita en células normales y cancerosas. Esta estructura se carac…
