Biologically young animals with long telomeres receive the bone marrow of biologically old animals with shortened [...] link between cardiovascular and pulmonary diseases. However, little is known about the molecular biological causes. A research team led by Professor Dr. Christian Bär from the Institute of Molecular and [...] so to speak, and the cell loses its ability to divide completely. “Telomer lengths are therefore biological markers of age,” explains Professor Bär. Chimeric mouse models with different organ and immune

Leibniz Research Laboratories for Biotechnology and Artificial Organs (LEBAO) want to develop a biological heart support system. So-called induced pluripotent stem cells (iPS cells) from genetically re [...] heart still has a reduced pumping capacity. Development according to the modular principle The biological heart prosthesis made from fibrin, heart muscle cells and heart valves is intended to compensate [...] The single-chamber heart is to be created in a modular fashion. The scientists want to develop biological components piece by piece and assemble them according to the modular principle. First, still u

Biological age can differ [...] healthy donors from the MHH Clinic for Transfusion Medicine and Tissue Engineering. Gender and biological age taken into account By comparing the data, the scientists were able to establish reference ranges

Molecular imaging provides a particularly precise insight, showing biological processes and organ functions "live" and can thus reveal the course of a disease or the effectiveness [...] sniffing substances find cells according to the lock-and-key principle "Molecular imaging makes biological mechanisms and organ functions in the living organism visible and is therefore enormously important
