Promoting patient safety by a novel combination of imaging technologies for biodegradable magnesium implants

As part of the Marie Skłodowska Curie Action (MSCA) the European Training Network MgSafe, 15 young researchers will investigate biodegradable magnesium implants. The project is coordinated by the Helmholtz Zentrum Geesthacht (HZG); it brings together eight universities and research institutions as well as four technology companies from eight European countries. The European Union (EU) provides a funding programme of about four million euros.

For their research, the young scientists will use various imaging methods, which will enable them to most precisely monitor the behaviour of magnesium implants during the process of bio-compatible degradation.The obtained multimodal imaging data will be combined with molecular biological / biochemical analysis, thereby increasing the information about physiological changes. All relevant biological and chemical in vivo and ex vivo data will be merged by computational 3D methods, simulations and machine learning approaches.

Prof. Dr. Regine Willumeit-Römer, coordinator of the project and Head of the Metallic Biomaterials Division at the Helmholtz Zentrum in Geesthacht, explains: "Biomedical imaging is fundamental to both diagnosis and therapy, because we need to monitor the behaviour of the degrading implant materials. There is still need for improvement as far as the new class of biodegradable magnesium-based implants is concerned. In the MgSafe project, we will establish new techniques while educating 15 PhD students interdisciplinary in both imaging and implant technologies."

Two researchers (Dr med. vet. Nina Angrisani, Hannover Medical School, and Prof. Dr Regine Willumeit-Römer, Helmholtz-Zentrum Geesthacht) and their work groups aim to develop an alternative treatment for cartilage lesions using degradable beads made of magnesium and a magnesium-alloy. The research is based on the assumption that magnesium improves the surrounding bone structure. Magnesium (alloy) beads will be implanted into subchondral bone tissue, where they are expected to degrade and thereby positively influence the surrounding tissue.

While magnesium is well-known in the scientific community as implant material, this may be the first attempt to deploy it in the treatment of damaged cartilage. The in vitro and in vivo tests will improve an understanding of magnesium's influence on bone and cartilage. A positive outcome may also significantly improve the treatment of osteoarthritis in the long term.

Based on available material, beads with dimensions of about 0.5 mm will be produced. Degradation properties and biocompatibility will be tested in vitro, followed by the employment of a well-known animal model to address the various research questions in and ex vivo, using methods such as µ-computer tomography, protein expression analysis and histological analysis.

Materials based on magnesium alloys for bioresorbable implants with anti-tumour activity

A Russian-German research collaboration in the fields of resorbable metallic implants as anti-tumour agents. Our Russian project partners are the National University of Science and Technology MISIS, NUST MISIS and the N.N. Blokhin Russian Cancer Research Center.

The project addresses a core problem in modern oncology: the application of local chemotherapy that aims to achieve an efficient concentration of anti-tumor agents in the intra- or peritumoral regions. The chosen approach based on degradable Mg-based implants is expected to result in a cytoreduction of unresectable and chemo-resistant tumors, while at the same time reducing the side effects for the patients.

SynchroLoad - Failure in biodegradable metal implants

A Swedish-German research collaboration in the fields of materials science and structural biology (Röntgen-Ångström-Cluster).

In this project, we aim to understand how implant degradation and failure mechanisms work for a biodegradable Mg implant where corrosion processes and (bio)chemistry form a complex network of interactions in the living system. The tissue-to-implant interface will be fully characterized biomechanically, morphologically, biologically and chemically. Finally, a comparison of the bone structure around different implant materials will be performed.

Materials for Brain: Thin film functional materials for minimally invasive therapy of brain diseases

Cooperation between the Christian-Albrechts-University of Kiel (CAU), the University Clinic of Schleswig-Holstein (UKSH) and the Helmholtz Center-Geesthacht (HZG).

Within the framework of the Graduate School, minimally invasive treatment strategies for diseases of the brain based on novel thin-film material compounds are to be explored in a complexity and functionality that goes far beyond previous approaches. The realisation of such treatment strategies in clinical medicine will be a milestone in the therapy of these diseases.

The development of such cutting-edge localized therapies and suitable functional materials requires substantial collaboration between materials science and medicine, as well as new approaches to solutions and creative openness to the view of the respective other subject.

VI MetBioMat - In vivo studies of biodegradable magnesium based implant materials

In collaboration with the university hospitals of Hamburg, Hannover and Graz as well as further partners, the Helmholtz-Zentrum Geesthacht had established a Virtual Institute, whose focus was on degradable magnesium implants. One aim of the research association coordinated from Geesthacht was to develop first prototypes of orthopaedic implants.

The Virtual Institute MetBioMat was one of the Helmholtz Virtual Institutes and lead by Prof. Regine Willumeit-Römer of the Helmholtz-Zentrum Geesthacht. By establishing new research partnerships, Helmholtz Virtual Institutes provided a distinct benefit in preparing the way for larger strategic research projects. With this funding the Helmholtz Association wanted to strengthen the position of universities in the German scientific system. A further aim of the funding programme was to generate new collaboration with leading international partner institutions and the industry.

EU-MSCA ETN MagnIM [289163] - Tailored biodegradable magnesium implant materials

Cost reduction and improvement of the quality of life is a major issue in health care. This challenge can be tackled by intelligent biomaterials and smart implants which are resorbed by the body upon remodelling of the tissue: What is possible for polymer materials should also be realized for biodegradable metallic materials. “MagnIM - Tailored biodegradable magnesium implant materials” trained 12 ESRs from 9 countries (3 male, 9 female) to contribute to this demanding aims by the development of new aluminium free magnesium implant materials with tailored properties specific for bone related applications especially in children and for sports medicine.

The project was structured such a way that it covered the complete value-added chain from material development and characterisation over in vitro to finally in vivo studies and application. Central point was the optimisation of material properties of aluminium free biodegradable magnesium alloys. To do so a new class of alloys considering computational tools was developed. The processing of the new alloys was be optimised leading to materials which were produced reliably and thus can be applied in orthopeadics and sports medicine. All materials were characterised as produced and in heat treated conditions to gain knowledge on the full property profile (microstructure, mechanical properties ), corrosion, in vitro and in vivo performance. Especially the latter were needed to bring a new implant into application. But as important was the aspect to bridge the gap between the observations made for Mg degradation in vitro and the fundamentally different results obtained in vivo. Therefore, comprehensive chemical understanding of corrosion were combined with the knowledge about cellular reactions to the new materials in order to create an in vitro test system which allowed for reliable prediction of the in vivo properties of the degradable material. To do so a complete set of parameters obtained from in vivo experiments was implemented in a feedback procedure.
