With this novel approach we will generate an biochemically engineered endosymbionic skin cell, which achieve the ability of autonomous, light and time controlled oxygen production. When engrafted, these neoendosymbionts would be able to stabilise the oxygen supply at the site of injury, thus counteracting tissue hypoxia and consequently enable enhanced wound closure. Our highly interdisciplinary research team is made up of scientist from different research fields including biochemistry (CBIB, Uni Bremen), cell biology (Genetics, Uni Bremen), marine biology (AWI, Bremerhaven), microsystems technology (IMSAS, Uni Bremen) and medical scientist (Klinikum-Munich; Tierärztliche Hochschule Hannover), providing an excellent scientific environment to target all the involved scientific and practical questions. For example, in cooperation with microsystems engineers (IMSAS, Uni Bremen) we developed a temperature and light controlled oxygen micro-sensor prototype for biochemical measurement of oxygen consumption and production by cells under physiological conditions. In summary, our concept represents an entirely new line of wound therapy for diabetic as well as for arteriosclerotic non-healing wounds and may also pave the way for a new generation of molecular cell engineering strategies.</p> <h3><strong>Contact:</strong></h3> <table> <tbody> <tr> <td> <p><a class="internalLink" href="t3://page?uid=5398" target="_blank" title="Öffnet internen Link in aktuellem Fenster">Dr. Mario Waespy (CBIB)</a><br /> NW2 B2190<br /> Phone: +49-421-218-63224<br /> E-Mail: <a class="mail" href="mailto:ma_wa@uni-bremen.de" title="Öffnet ein Fenster zum Versenden der E-Mail">ma_wa@uni-bremen.de</a></p> </td> <td><a class="internalLink" href="t3://page?uid=21129" target="_blank" title="Öffnet internen Link in aktuellem Fenster">Prof. Dr. Dr. Ursula Mirastschijski (CBIB)</a><br /> NW2 B2190<br /> Phone: +49-421-218-63224<br /> E-Mail: <a class="mail" href="mailto:mirastsc@uni-bremen.de" title="Öffnet ein Fenster zum Versenden der E-Mail">mirastsc@uni-bremen.de</a><br />  </td> </tr> <tr> <td> <p><a class="internalLink" href="t3://page?uid=5389" target="_blank" title="Öffnet internen Link in aktuellem Fenster">Prof. Dr. Sørge Kelm (CBIB)</a><br /> NW2 B2235<br /> Phone.: +49-421-218-63222<br /> E-Mail:<a class="mail" href="mailto: skelm@uni-bremen.de" title="Öffnet ein Fenster zum Versenden der E-Mail"> skelm@uni-bremen.de</a></p> </td> <td> <p><a class="externalLink" href="http://www.imsas.uni-bremen.de/" target="_blank" title="Öffnet externen Link in neuem Fenster">Prof. Dr.-Ing.
