New nanoarchitectonics of RGD peptide developed using quatsomes as robust tool in tissue engineering.

Researchers of three groups of CIBER-BBN at CSIC and IBEC, have created a versatile platform based on hierarchically nanostructured RGD peptide using quatsomes, with proved enhanced cell adhesion. These findings, which arose within the framework of the intramural project of CIBER-BBN “Molecular Biointerfaces for cell guidance” (DynaMo4Vasc), open new possibilities for tissue engineering.

The participation of two NANBIOSIS units were acknowledged in the publication of the research results: the synthesis of RGD derivatives were performed at NANBIOSIS U3 “Synthesis of peptides unit” of CIBER-BBN at IQAC−CSIC.  And the design and characterization of quatsomes were done at U6 of NANBIOSIS “Biomaterial Processing and Nanostructuring Unit” of CIBER-BBN at ICMAB-CSIC.

Tissue Engineering and cell adhesion

Tissue engineering pursues the development of functional and easy biological substitutes that allow restoring damaged organ or tissue or maintaining their normal function. The newer approach is the combination of appropriate cells and growth factors with a scaffold that supports the tissue or organ.

The scaffold is crucial since it must provide the conditions and the environment for the adequate cell regulation (adhesion, migration, proliferation, and differentiation), as well as the adequate delivery of bioactive factors (growth and adhesion), so that cells form the new tissue with its proper structure and function.

Cell adhesion (the interaction of the cells with its surroundings) is an important phenomenon for the development of appropriate scaffolds for tissue engineering, as it can ultimately determine cell fate. Thus, the study of the factors that govern cell adhesion and its optimization is essential.

The tripeptide Arg-Gly-Asp (RGD) is the most common peptide responsible for cell adhesion. Although the studies of its surface density and spacing at nanoscale have already shown a significant influence on cell adhesion, the impact of its hierarchical nanostructure is still unexplored.

Quatsomes

Quatsomes are non-liposomal nanovesicles which have been shown to be very homogeneous and stable in different media and which can be easily tuned with a wide range of chemical functionalities.

The Nanomol Group (from CIBER-BBN and ICMAB-CSIC) has been working during the last years with these nanoparticles showing their suitability for applications in nanomedicine, (as nanocarriers and nanocontainers to encapsulate drugs and protein cargoes, or as fluorescent dyes for therapy and diagnostics). This expertise led the researcher to explore the integration of quatsomes with relevant molecules and their use once anchored to a surface.

RGD Nanoarchitecnonics

Nanoarchitectonics is a novel concept that refers to multicomponent systems organized through the supramolecular union of nanometer structures where the main players are not the individual nanoparticles but their interactions, giving rise to new functionalities.

The team of researchers developed a versatile platform based on quatsomes as an effective nanoscopic building block to achieve hierarchical nanostructures of the RGD peptide which were further anchored to gold substrate. In comparison with substrates featuring a homogeneous distribution of RGD peptides, the resulting hierarchical nanoarchitectonic surfaces dramatically enhanced cell adhesion.

These findings open many possible pathways for the understanding of cell behaviour and improve the performance of clinical applications like implants and tissue engineering.

New European Project NABIHEAL in biomaterials for complex wound healing

The Horizon Europe project NABIHEAL, coordinated by the Center for Biomedical Research Network (CIBER) at the Institute of Materials Science of Barcelona (ICMAB-CSIC), was launched on 11-12 January 2023 in Barcelona with the first meeting of the international consortium, formed by 14 partners from 7 countries, including research centers, universities, and private companies. 

This project will apply one the “Cutting Edge Biomedical Solutions” of NANBIOSIS for the preparation of different nanoestructures with antimicrobial properties, required for the development of the final multifunctional wound healing biomaterials. This case will gather the expertise of two NANBIOSIS unit: NANBIOSIS U6 will produce and characterize these nanoestructures with antimicrobial properties, which will be tested in NANBIOSIS U16.

NABIHEAL stands for “Antimicrobial Nanostructured Biomaterials for Complex Wound Healing” and is funded under the Horizon Europe Research and Innovation programme with a total budget of nearly 5 million euros over four years. NABIHEAL aims at solving two unmet medical needs in complex wound healing: on the one hand, affordable treatments for wound infections and prevention of complications during wound healing, and on the other, a strategy to optimize the composition and efficacy of wound dressings.

The kickoff meeting, held at the CSIC Researcher’s Residence in Barcelona, was opened by the project coordinator, Nora Ventosa, from CIBER and ICMAB-CSIC, and by institutional and political representatives, including Riccardo Rurali, Vice-Director of ICMAB-CSIC; Ramon Martínez Mañez, Scientific Director of CIBER-BBN; Jordi Aguasca, Director of Technological Transformation and Disruption Unit, ACCIÓ; and Xavier Aldeguer, General Director of Society of Knowledge, Transfer & Territory of the Catalan Government. The meeting provided the opportunity to interact in person with all the consortium partners and establish the first collaborative activities to ensure timely delivery of the project milestones.

Complex wound healing as a global health problem

The NABIHEAL project will advance on the synthesis of advanced nanostructured biomaterials as an alternative to the commonly used silver-based materials. “The project will work to produce multifunctional materials for the treatment of complex wound healing, which has become a global health problem. For example, in developed countries, it affects the quality of life of more than 2% of the total population,” affirms Nora Ventosa, coordinator of the project.

Complex wounds, such as chronic wounds, are highly susceptible to microbial infection and biofilm formation, and thus difficult to treat. The most common antimicrobial products to treat these infections are based on silver. However, they have several economic, environmental and safety drawbacks. The biomaterials developed within the NABIHEAL project will offer a safer, more sustainable and more cost-effective alternative.

The project aims to obtain innovative multifunctional wound healing biomaterials using affordable EU-based manufacturing technologies. In the long term, NABIHEAL could become a game-changing alternative to silver in wound healing dressings.

An International Consortium

The goals of the project will be tackled by an interdisciplinary consortium from 7 countries, combining expertise in different areas, such as synthesis and characterization of biomaterials, biocompatibility and safety, regulatory aspects and ethics, or wound healing product development and scale-up. “We are excited to launch this project, in which 8 academic institutions and 6 private companies will join forces to face the challenging problem of complex wound treatment,” adds Prof. Ventosa.  

In addition to the Center for Biomedical Research Network (CIBER) at the Institute of Materials Science of Barcelona (ICMAB), as coordinator, the international consortium is formed by the following centers and companies: from Spain, the Center for Biomedical Research Network (CIBER) at the University of Extremadura and the University of Cantabria, the Spanish National Research Council (CSIC), Nanomol Technologies S.L. (NT), Bioiberica S.A.U (BIO), Histocell S.L (HCELL), the University of Granada (UGR), and Asphalion (ASPH); from Germany, MyBiotech GmbH (MyB) and Charité-Universitätsmedizin Berlin (CH); from Croatia, the Institute for Medical Research and Occupational Health (IMI); from Denmark, the Aarhus University (AU); from Israel, the Technion-Israel Institute of Technology (IT); from Austria, BioNanoNet Forschungsgesellschaft mbH (BNN); and from Slovenia, the University of Maribor (UM).
