Relevant research results for assisted reproduction.

Javier García Casado, Scientific Director of NANBIOSIS Unit 14: Cell therapy toguether with other Scientists of NANBIOSIS and CCMIJU have issued the first report describing the beneficial effect of human EV-endMSCs on embryo development, which has been recently published by PloS One: “Murine embryos exposed to human endometrial MSCs-derived extracellular vesicles exhibit higher VEGF/PDGF AA release, increased blastomere count and hatching rates“.  The results could be relevant for assisted reproduction:

“Endometrial Mesenchymal Stromal Cells (endMSCs) are multipotent cells with immunomodulatory and pro-regenerative activity which is mainly mediated by a paracrine effect. The exosomes released by MSCs have become a promising therapeutic tool for the treatment of immune-mediated diseases. More specifically, extracellular vesicles derived from endMSCs (EV-endMSCs) have demonstrated a cardioprotective effect through the release of anti-apoptotic and pro-angiogenic factors. Here we hypothesize that EV-endMSCs may be used as a co-adjuvant to improve in vitro fertilization outcomes and embryo quality. Firstly, endMSCs and EV-endMSCs were isolated and phenotypically characterized for in vitro assays. Then, in vitro studies were performed on murine embryos co-cultured with EV-endMSCs at different concentrations. Our results firstly demonstrated a significant increase on the total blastomere count of expanded murine blastocysts. Moreover, EV-endMSCs triggered the release of pro-angiogenic molecules from embryos demonstrating an EV-endMSCs concentration-dependent increase of VEGF and PDGF-AA. The release of VEGF and PDGF-AA by the embryos may indicate that the beneficial effect of EV-endMSCs could be mediating not only an increase in the blastocyst’s total cell number, but also may promote endometrial angiogenesis, vascularization, differentiation and tissue remodeling”.

Soluble factors were analyzed by the ICTS Nanbiosis (Unit 14. Cell therapy at CCMIJU). Maintenance of animals was performed by the ICTS Nanbiosis (Unit 22. Animal housing at CCMIJU). In vivo embryo recovery and culture was performed by the ICTS Nanbiosis (Unit 23. Assisted Reproduction at CCMIJU)

Prof. A. Villaverde interviewed by CIBER-BBN Bulletin

Prof. Antoni Villaverde, Strategy Director of NANBIOSIS U1. Protein Production Platform (PPP), in an interview for the CIBER-BBN Bulletin, speaks about his research group, coordinanting NANBIOSIS u1 and the benefits of belonging to a research structure like CIBER.

“The PPP – explains Prof. Villaverde – was generated within the group, but is currently a platform that has been gaining its own entity and structure, and has received the ISO certification granted by AENOR. Neus Ferrer-Miralles is the Scientific Director and Paolo Saccardo the technical coordinator. The objective of the activity developed by the PPP is based on supporting CIBER groups in the production and purification of recombinant proteins within the field of nanomedicine. The fact that this service has emerged within a powerful research group allows the accumulated knowledge and experience to directly revert to the needs in this field within the area of ​​nanomedicine in our country. Therefore, with the aim of reaching society, in addition to the CIBER, we also provide service to public and private entities dedicated to research and pharmaceutical companies”.

According to Toni Villaverde “The incorporation of the group to the CIBER-BBN has represented a clear and deap positive impact on our activities, at a collaborative level, which has greatly enriched our scientific and methodological capabilities and which has allowed a multidisciplinary scientific activity, which otherwise It would not have been possible. Since the beginning of the CIBER, we have carried out punctual collaboration activities with various groups of CIBER, and we have generated more stable collaborative structures that allow scientific developments in the medium-long term. Among the latter, it is necessary to highlight the collaboration with the group of Dr. Mangues and  Dras. Isolda Casanova and Virtudes Céspedes,- coordinating NANBIOSIS U18.Nanotoxicology Unit, Profs. Veciana y Ventosa, coordinatinatin NANBIOSIS U6. Biomaterial Processing and Nanostructuring Unit, as well as of the group coordinated by Prof. Schwartz and Dr. Abasolo” –NANBIOSIS U20. In Vivo Experimental Platform-.

In this interview, Dr. Villaverde reviews the main research lines and projects that the research group at the Institute of Biotechnology and Biomedicine of the Autonomous University of Barcelona, coordinator of the NANBIOSIS U1.PPP, is currently developing (nanostructured protein materials as therapeutic anti-inflammatory agents, nano and protein microstructures for drug delivery in targeted therapies and new drugs for rare diseases, nanoconjugates based on self-assembling proteins for targeted cancer therapy, self-assembling and nanostructured protein drugs, produced in recombinant form and based on very potent toxins, for targeted molecular therapy of cancer… and much more…) .

Nosological images of response to therapy based on metabolomic information by magnetic resonance

Ana Paula Candiota, Scientific Coordinator of NANBIOSIS U25. NMR: Biomedical Applications I. is givin a talk about “Nosological images of response to therapy based on metabolomic information by magnetic resonance: a step beyond the standard image” next June 6, on Barcelona.

According to Dr. Candiota, “The reliable characterization of the treatment response in glioblastoma (GB) is a key factor in improving the survival and prognosis of patients. Image (MRI) and spectroscopic image (MRSI) by magnetic resonance respectively provide morphological and metabolotic profiles of GB, but in general they are not as robust to produce surrogate biomarkers in response to short-term therapy. One of our objectives is to try to provide clinicians with a reliable way to follow the response to therapy in a more adjusted temporal window for changes or adaptations of the therapy, and in a more early way than the one currently performed using MRI.  This part of the course will emphasize the potentiality of the systems of patterrn recognition / machine learning to produce ‘nosological images’ to recognize in a robust way the response to temozolamide (TMZ) therapy in preclinical GB (glioblastoma GL261 murine model in the immunocompetent strain C57 / BL / 6), based on the information of the magnetic resonance spectroscopic images. Despite being developed on a preclinical model of pathology, these techniques have a clear translational potential and could in the future improve the management of the different aspects of the treatment of patients”.

The talk will take place in the Conference: Nanotechnology applied to medicine as a learning resource for healthcare professionals, organized by Union Consorci Formació in Barcelona (Parc Sanitari Pere Virgili, Edifici Montseny planta -1).

The objective of the event is to summarize the most significant advances that have been made in this field, both at the level of development of nanomaterials, as well as in the most relevant applications of the different nano-pharmaceuticals that are on the market, to end up highlighting the future challenges to which faces nanomedicine to increase the efficiency and specificity of nanomedication.

Carbon-gold bonds for robusts molecule-electrode junctions

Marta Mas-Torrent, Jaume Veciana, and Nuria Crivillers, scientists of the research group NANOMOL, coordinating NANBIOSIS U6. Biomaterial Processing and Nanostructuring Unit, are co-authors of the article “Carbon-gold bonds for robusts molecule-electrode junctions” by  Journal of the American Chemical Society -JACS-.

The researchers have studied the behaviour of an organic radical as a molecular wire formed by a covalent carbon-gold bond between the molecule and two electrodes. The molecule-metal junction is more stable and gemotrically better defined than its predecessors, in which other functional groups were used. This improvement opens up new horizons in the fabrication of novel electronic devices with applications in the Molecular Electronics field.

Mesenchymal stem cells or exosomes with fibrin glue mesh fixation modulates the inflammatory reaction in a murine model of incisional hernia

Javier García Casado, Scientific Director of NANBIOSIS U14, Cell Therapy Unit, and Francisco Miguel Sánchez Margallo, Scientific Director of  CCMIJU, are co-author of the publication “Fibrin glue mesh fixation combined with mesenchymal stem cells or exosomes modulates the inflammatory reaction in a murine model of incisional hernia” by Acta Biomaterialia.

In vitro experiments were performed by the ICTS Nanbiosis (Unit 14. Cell therapy at CCMIJU). Exosomes characterization was performed by the ICTS Nanbiosis (Unit 6: Biomaterial processing and Nanostructuring Unit). In vivo experiments were performed by the ICTS Nanbiosis (Unit 22. Animal housing at CCMIJU).

The study has demonstrated a significant increase of anti-inflammatory M2 macrophages and TH2 cytokines when MSCs or exo-MSCs were used. Moreover, the analysis of MMPs, TIMPs and collagen exerted significant differences in the extracellular matrix and in the remodeling process. The in vivo study suggests that the fixation of surgical meshes with FG and MSCs or exo-MSCs will have a beneficial effect for the treatment of incisional hernia in terms of improved outcomes of damaged tissue, and especially, in the modulation of inflammatory responses towards a less aggressive and pro-regenerative profil,

The implantation of surgical meshes is the standard procedure to reinforce tissue defects such as hernias. However, an exacerbated and persistent inflammatory response secondary to this implantation is frequently observed, leading to a strong discomfort and chronic pain in the patients. In many cases, an additional surgical intervention is needed to remove the mesh.

This study shows that mesenchymal stem cells and their exosomes, combined with a fibrin sealant, can be used for the successful fixation of these meshes. This new therapeutic approach, assayed in a murine model of incisional hernia, favors the modulation of the inflammatory response towards a less aggressive and pro-regenerative profile
