Extracellular vesicles secreted by cancer stem cells promote angiogenesis and disease progression

Patricia González, researcher of the “Drug Delivery and Targeting” of CIBER-BBN and VHIR, presented her thesis work on November 19 where she lays the foundations to understand the role of different subpopulations of extracellular vesicles (VEs) secreted by tumor models in the regulation of tumor plasticity, as well as its effect on the tumor microenvironment and disease progression.

In the project, it has been described for the first time how the VEs secreted by the cancer stem cell subpopulation are responsible for activating fibroblasts in the tumor microenvironment and promoting angiogenesis, thus facilitating disease progression. Furthermore, it has been possible to discern the role of these vesicles in the regulation of cell plasticity. In this sense, the VEs from tumor stem cells would act as effectors of cell differentiation in contrast to the action of the VEs secreted by differentiated cancer cells, which would stimulate the acquisition of stem cell characteristics.

In order to carry out the in vivo experiments, the services of ICTS Nanbiosis were used, through the U20.

The results open a new line of research in the group with a long journey ahead, setting as main objectives the identification of the molecular actors responsible for the activities described above as well as the translation of said knowledge into specific therapeutic strategies.

New Equipment available for the Regenerative Medicine Research Line of the U10 of NANBIOSIS

The Unit 10 of Drug Formulation of the ICTS NANBIOSIS coordinated by the CIBER-BBN NanoBioCel group directed by Jose Luis Pedraz, which belongs to the University of the Basque Country, has been present at the signing of the agreement that gives support by the Provincial Council of Alava within the framework of the Advance Pharma Development project, together with the research and technological development center TECNALIA.

With this agreement, the NanoBioCel research group will receive in the next two years (2021-2023) a contribution of 650,000 €, which will allow the hiring of research personnel and the purchase of specific equipment for the regenerative medicine research line. The first equipment purchased to strengthen U10 in Bio-printing is the RegenHU Bioprinter: R-GEN 100, which will be located in the P3 Laboratory of the Lascaray Research Building. This bioprinter will bring two new technologies to the bioprinting techniques currently being used at U10: extrusion and droplet techniques. With RegenHU it will be possible to work with two new bioprinting processes: electrospinning and electrowriting. Electrospinning is a promising technique for the controlled release of drugs and electrowriting (electrostatic writing) will allow the construction of scaffolds with variable diameters in their design and elaboration.

‘Point-of-care or PoC’ devices are able to directly detect the genetic material of the virus in just 30 minutes

Twenty five Spanish researchers linked to the Higher Center for Scientific Research, CSIC, who are working more directly on the project ‘Point-of-care tests for the rapid detection of SARS-CoV-2’ – Studies for the development of technologies effective diagnosis and early detection of SARS-CoV-2- have met since last Wednesday and until this Friday at the Benasque Science Center ‘Pedro Pascual’ to analyze the state or of the different programs and lines of research on the covid-19.

After months of intense work, among the most outstanding achievements in relation to the detection of the genetic material of the virus, is the development of a series of technologies that allow this detection without the need for PCR. Researchers have managed, by designing specific probes, to directly detect the genetic material of the virus in just 30 minutes.

Dra. Pila r Marco, researchar of CSIC and Scientific Director of Nanbiosis U2 Custom Antibody Service (CAbS) – explains that “the PCR technique, which it is very sensitive and very precise, has a disadvantage in terms of time because it requires an amplification stage of this genetic material that makes the process long, this is going to revolutionize the diagnosis, not only for Covid-19, but also of other infectious diseases”.

Researcher of three units of NANBIOSIS, attended the meeting and some of them gave talks:

Nuria Pascual, Scientific Coordinator of NANBIOSIS U2 CAbS espoke about Antibodies production
Also from NANBIOSIS Unit 2, J. Pablo Salvador espoke about Immunochemical tests and .
Serological test of peptide epitopes were explained by Julian Guercetti.
Anna Avigñó, Scientific Coordinator of NANBIOSIS U29, espoke about Design of oligonucleotides for a new method in Covid-19 detection without PCR.
And Macarena Duran, representing MS4N group and the Peptide synthesis unit of NANBIOSIS (U3) explained the synthesis of potential SARS-COV2 epitopes that have been applied for hybridome selection for mAb and to generate epitope microarrays to analyze serological samples.

The meeting has served to share the most relevant results that have been obtained in the context of the project, as well as discussion of new strategies to address problems that have arisen throughout the project and in turn, discuss future objectives.

Colloidal nanocrystals for energy applications

Semiconductors are materials used in a wide ranfe of applications since they are capable of capturing light and allowing us to take advantage of it. In addition, if we reduce its size to the nanometric scale we can activate additional very interesting properties

On October 16, “Technoscience and Energy” took place in Inseec, Lyon (France), a science-industry transfer event between French and Spanish companies and researchers from the energy sector in France. Among the invited speakers was María Bernechea Navarro, ARAID Investigator, at the Institute of Nanoscience and Materials of Aragon at University of Zaragoza-INMA.

In her talk, entitled “COLLOIDAL NANOCRYSTALS FOR ENERGY APPLICATIONS”, María Bernechea showed the development of nanomaterials stabilized in solution (to facilitate working with them), composed of abundant and non-toxic elements, as well as their use in various applications related to clean energy.

“We synthesize colloidal nanosemiconductors that are used for different applications. We mainly use these nanomaterials to harvest solar light and convert it into electrical current (solar cells) or remove pollutants in wastewater (using the materials as photocatalysts). More recently we have started to study the incorporation of these materials on carbon supports to fabricate electrodes that can be used in electrochemical storage devices (batteries or supercapacitors). These nanosemiconductors are fabricated at the NANBIOSIS U9 Synthesis of Nanoparticles Unit of CIBER-BBN and the INMA”, has explained María.

Last October 29, María Bernechea gave also a talk at the Faculty of Sciences of La Coruña entitled, “Colloidal Nano-Semiconductors for solar cells and other applications” that is avalilable in youtube. Dr. Bermechea expressly thanked the access to the ICTS NANBIOSIS for the development of these semiconductors.

NANBIOSIS U12 “Nanostructured liquid characterization unit” of IQAC-CSIC and CIBER-BBN, led by Dr. Carlos Rodriguez Abreu and D. Jordi Esquena, has implemented a Quality Management System for the scope of Technological service for characterization of colloidal dispersions, which fulfills the requirements of the standard ISO 9001:2015. An IQNet recognized certificate has been issued by AENOR last week.

This certification will expand and consolidate the service that Unit 12 of NANBIOSIS is giving to companies and public sector researchers and facilitate their integration in cooperative international projects.

The ISO 9001 Standard is the most widespread Quality Management tool worldwide, with over one million certificates in 175 countries. The main objective of the standard is to increase customer satisfaction through continuous improvement processes. It is designed so that the organizations that apply it can guarantee their ability to offer services that meet the requirements of their customers. This international standard promotes the adoption of a process-based approach when the effectiveness of a quality management system is developed, implemented and improved, based in turn on the PDCA (Plan, Do, Check, Act) continuous improvement cycle.

The main benefits derived from ISO 9001 certification for organizations are: systematization of operations, improvement of internal organization, generation of a higher level of confidence in the internal and external environment, increased competitiveness, guarantee of compliance with legislation and regulations related to products and services, among others
