Programme

Unfurtunately the monastery Irsee has been closed by the Bavarian government due to the corona virus.

Therefore we have decided to offer the conference as a web conference only.

In those unpredictable times, protecting our participants’ health has the highest priority for us!

The scientific exchange must not come to a complete standstill and we believe that with this web solution we have found a way to keep the scientific community going.

In order to participate in the livestream of the conference as easy as possible and to give your presentation, we recommend the use of the web browsers Google Chrome or Microsoft Edge.

Here you can find detailed instructions for using the livestream.

As a participant of the Bioinspired 2020 you have received an e-mail containing the login data for the web conference.

The login data for the sessions are provided daily.

In order to allow all conference participants access to the posters, we ask you to upload your poster by login on the conference homepage and clicking on the button "My Submission" in the upper right corner of the conference homepage. Then select the submission to which you want to upload the poster and upload the poster at the bottom of the page.

Furthermore we would like to ask all poster authors to prepare 4 PowerPoint slides to present your poster to the audience.
Please also include your contact details on the digital poster to allow participants to reach you with questions.

Please note that your poster will be pictured publically.

As poster author you can upload your poster similar to the way you submitted your abstract.
Click on "My Submissions" in the upper right corner at the homepage.

Poster documents can be found by opening the respective abstract in the online programme.
If a poster document has already been uploaded for the abstract, it can then be opened and downloaded.

Please note that your poster will be pictured publically.

You can ask your questions via chat already during the presentations!
Please use for this the Q&A (F&A) button!

For further scientific exchange we implemented a discussion forum on the homepage of the DGM.
Please visit discussion.dgm.de and use your DGM or Bioinspired user credentials to login.

Special Poster Session Biofabrication

Establishment of a fiber-based and RGD-modified spider silk for the generation of a drug-producing tissue container

Tuesday (17.03.2020)
18:19 - 18:22

Introduction: Targeted therapies with biologicals are of growing clinical importance in the treatment of autoimmune diseases or cancer. Although auspicious, there are limitations in the broad medical application: the production of biologicals is complex and expensive and the serum half-life time of some biologicals is short requiring frequent injections or infusions. The generation of a drug-producing tissue container vascularized by an AV loop and implanted in the patient seems to be a promising approach to solve this problem. This study aimed at the establishment of an ideal carrier matrix based on recombinant engineered spider silk for the generation of a transplantable therapeutic tissue container.

Materials and methods: For cytocompatibility and drug release testing in vitro, genetically modified HEK293 cells, producing a reporter molecule consisting of the extracellular domain of TNFR2 linked to luciferase, were incorporated into recombinant engineered ADF4(C16)-RGD spider silk. Furthermore, biocompatibility and angiogenesis were assessed in the rat AV loop model using µCT and histology.

Results: Modifying the eADF4(C16) spider silk with the RGD motive supported cell viability as well as the production of the reporter molecule. Moreover, we were able to prove a slow biodegradation and incipient vascularization of constructs containing eADF4(C16)-RGD spider silk. Although, macrophages were present in the histological specimen no signs of severe immunoreaction were observed.

Conclusion: This study demonstrates the impact of modifying engineered ADF4(C16) spider silk with functional groups on cytocompatibility, protein production as well as angiogenesis. The use of engineered ADF4(C16)-RGD spider silk enables new possibilities for the establishment of a transplantable therapeutic tissue container.
