New DFG research group FOR 5628 with our participation
Stacks Image 28342
The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) is establishing eight new research groups. One of these groups is FOR 5628: "Multiscale magnetic resonance elastography in cancer: The mechanical niche of tumor formation and metastatic spread – towards an improved diagnosis of cancer through mechanical imaging". The speaker and initiator is Prof. Ingolf Sack.

During the development of a tumour, the tissue changes its shape, e.g., alternating between hard and fluidic states. For this, cells exert forces and are simultaneously influenced by forces. This research group is investigating which mechanical-physical processes are behind this. How do tumours and metastases develop? What makes them resistant to therapy? The team is investigating these questions using magnetic resonance elastography (MRE) – a new clinical procedure that can be used to record the mechanical properties of body tissue. The goal is to be able to better diagnose tumours.
Dr. Karl Hillebrandt and Prof. Dr. Igor Sauer are part of the research group as PI in three projects:
  • A03 Cancer cell unjamming and jamming as prerequisites for the formation of primary and metastatic tumors
  • B03 Scaffold composition and fluid pressure in recellularized hepatic and pancreatic tumors
  • C01 Multiscale mechanical properties of tumors and tumor environment – from tissue specimens to patients

Was are happy to be part of this exzellent team!
Moderate LMWH anticoagulation improves success rate of hind limb allotransplantation in mice
Stacks Image 28347
The publication "Moderate LMWH Anticoagulation Improves Success Rate of Hind Limb Allotransplantation in Mice" is now available online in Plastic & Reconstructive Surgery-Global Open. Authors are B. Kern, M.-I. Ashraf, A. Reutzel-Selke, J. Mengwasser, D. Polenz, E. Michaels, J. Pratschke, S.G. Tullius, Ch. Witzel, and I.M. Sauer.

The mouse hind limb model represents a powerful research tool in vascularized composite tissue allotransplantation, but its applicability is limited due to poor graft survival (62%–83%). Vascular thrombosis and massive hemorrhage are the major causes for these drop-outs. We hypothesize that because of better anticoagulation effect and lower risk of thrombocytopenia, application of low molecular weight heparin (LMWH) will minimize vascular complications and enhance graft and animal survival.

Fifty allogeneic hind limb transplantations were performed (C57BL/6 to DBA/2 mice) using five different anticoagulation protocols. Bleeding and thromboembolic events were recorded macroscopically by postoperative hemorrhage and livid discoloration of the graft, respectively. Graft perfusion and survival were monitored daily by capillary-refill-time of graft toes within 2–3 seconds. Vascular congestion and tissue necrosis were examined by histological evaluation of hematoxylin-eosin-stained tissue sections.

All transplantations were technically successful. Increase in thromboembolic events and a concomitant decrease in bleeding events were observed with the decreasing concentration of heparin in the perfusion solution. Although treatment of donor and recipient with low dose of LMWH could not reduce thromboembolic events, moderate dose effectively reduced these events. Compared with the poor outcome of graft perfusion with heparin alone, additional treatment of donor and recipient with low dose of LMWH improved graft and animal survival by 18%. Interestingly, animals treated with moderate dose of LMWH demonstrated 100% graft and animal survival.
Treatment of donor and recipient mice with a moderate dose of LMWH prevents vascular complications and improves the outcome of murine hind limb transplants.

science x media Tandem Program: "From Slices to Spaces"
Prof. Dr. Moritz Queisner and Frédéric Eyl (Designer and Managing Director of TheGreenEyl) successfully applied to the Stiftung Charité for funding as a "science x media tandem".
The science x media tandems are the first programme in the new funding priority "Open Life Science". With this funding priority, the Charité Foundation is working to make the life sciences in Berlin more comprehensible and accessible to a broader public and to strengthen the trustworthiness of medical professionals.

Under the title "From Slices to Spaces", the tandem of Moritz Queisner and Frédéric Eyl is implementing a science parcours in which spatially complex research data from surgery and biomedicine will be made multisensually accessible to a broad audience through new visualization techniques. Building on research work on new imaging techniques by Moritz Queisner, they employ Extended Reality techniques. Due to their unique ability to link digital objects with the real environment of the viewers, the 4D images they generate are particularly suited for representing and conveying spatial information.

This is where the tandem's project comes in: 4D images are not only interesting for researchers to understand complex research data but can also provide laypeople with a less presupposing insight into research data and processes. Frédéric Eyl's media expertise will be used to make the specific visual knowledge from research comprehensible and experiential for non-experts. The science parcours is intended to integrate as a digital extension into the architecture of the new research building, "Der Simulierte Mensch", located on the premises of Charité. The parcours will include the facade, the inter-floor airspace, and the central glass surfaces within the building as its stations. By enabling users to explore 4D research data within the architecture and investigate it using their own smartphones in an AR application, concrete practices and deployment locations of new image-based technologies become experiential and comprehensible. This project not only enhances the perception of Charité and the scientific location of Berlin but also opens up places of knowledge creation to the public, making practices and techniques of life sciences more visible.

New DFG project "4D Imaging"
Stacks Image 28436
The DFG Schwerpunktprogramm „Das Digitale Bild“ (SPP 2172) funds the new project “4D Imaging: From Image Theory to Imaging Practice” (2023-2026). Principal investigators are Prof. Dr. Kathrin Friedrich (Universität Bonn) and Prof. Dr. Moritz Queisner.

The term 4D imaging refers to a new form of digital visuality in which image, action and space are inextricably interwoven. 4D technologies capture, process and transmit information about physical space and make it computable in real time. Changes due to movements and actions become calculable in real time, making 4D images particularly important in aesthetic and operational contexts where they reconceptualize various forms of human-computer interaction. The 4D Imaging project responds to the growing need in medicine to understand, use, and design these complex imaging techniques. It transfers critical reflexive knowledge from research into clinical practices to enable surgeons to use and apply 4D Imaging techniques. Especially in surgical planning, 4D Imaging techniques may improve the understanding and accessibility of spatially complex anatomical structures. To this end, the project is developing approaches to how 4D imaging can complement and transform established topographic ("2D") imaging practices.

Design Lab #13: Material Legacies
The exhibition »Design Lab #13: Material Legacies« at Kunstgewerbemuseum Berlin, opening on November 3rd, 2022, explores contingencies and ruptures between traditional crafts and the most recent developments at the crossroads of material research, design, engineering, and architecture. It brings together artifacts from the museum’s collection with work-in-progress installations by designers and researchers from the Cluster of Excellence »Matters of Activity. Image Space Material« in order to initiate a dialogue about the historical, contemporary, and future conditions under which materiality unfolds.

By engaging with a series of different materials and techniques the exhibition encompasses both the problematization of unsustainable pasts and presents as well as the imagination of speculative material futures. Taking materiality as a starting point, each of the exhibits will investigate its sociocultural, economic, and political context in order to disentangle the multiple interrelations that arise from and with materials. As such »Design Lab #13: Material Legacies« aims to challenge the passive understandings of materiality and associate with the widening discourse on relational knowledge practices in arts, design, humanities, and social science.

The exhibition will be running from 4 November 2022 to 26 February 2023. For the exhibition announcement on the website of the

BMBF funds KIARA
With the programme "AI-based assistance systems for process-accompanying health applications", the Federal Ministry of Education and Research (BMBF) is funding innovative research and development work on interactive assistance systems that support processes in clinical health care using artificial intelligence methods.

Together with the partners Gebrüder Martin GmbH & Co. KG, Tuttlingen, HFC Human-Factors-Consult GmbH, Berlin and the Fraunhofer Institute for Telecommunications Heinrich-Hertz-Institut (HHI), Berlin, we successfully applied with the project "AI-based recording of work processes in the operating theatre for the automated compilation of the operating theatre report" (KIARA).


Stacks Image 28492


Operating theatre reports document all relevant information during surgical interventions. They serve to ensure therapeutic safety and accountability and as proof of performance. The preparation of the OR report is time-consuming and ties up valuable working time – time that is then not available for the treatment of patients.

In the KIARA project, we are working on a system that automatically drafts operating theatre reports. The KIARA system is intended to relieve medical staff: it documents operating theatre activities and creates a draft of the report, which then only needs to be checked, completed and approved. The system works via cameras integrated into operating theatre lamps. Their image data is then analysed with the help of artificial intelligence to recognise and record objects, people and all operating theatre activities. The ambitious system is to be developed and tested in a user-centred manner for procedures in the abdominal cavity and in oral and maxillofacial surgery.

KIARA is intended to continuously learn through human feedback and to simplify clinical processes for the benefit of medical staff by automating the creation of operating theatre reports. The system can also be applied to other operating theatre areas in the future.

The project has a financial volume of € 2.16 million.
The kick-off meeting took place on 16.09.2022 at the Charité.

DFG Walter-Benjamin grant for the investigation of sex as a biological variable in alloimmunity
Stacks Image 28511
With a DFG Walter-Benjamin grant Dr. med. Friederike Martin will join the laboratory of Transplant Surgery Research at Harvard under the direction of Professor Stefan G. Tullius in Boston to investigate the role of biological sex for transplantation outcome.

Influences of donor and recipient sex on transplantation outcome have been described manifold, as well as an influence of sex hormones on the innate and adaptive immune response. So far, research, investigating the impact of sex hormones and different sex- and age-dependent sex-hormone levels on alloimmune response after solid organ transplantation is lacking. The aim of the project “Sex as a biological Variable in Alloimmunity” is, to delineate the impact of sex hormones and especially estrogens and age-dependent changes in estrogen-levels on alloimmune response after allogenic transplantation.  The project is based on the publication “Recipient sex and estradiol levels affect transplant outcomes in an age-specific fashion” published in the AJT in 2021 by the workgroup of Prof. Tullius.

Friederike, who already received the Sanofi Women in Transplantation fellowship grant for research in gender and sex in transplantation in 2021, will work as a Postdoc on this project in the Tullius Lab for an expected 2 years period, starting in January 2023.
