    Blood-Brain Barrier: CSF Proteins

    Maintenance of Brain Homeostasis by Sugar Structures CSF – cerebrospinal fluid, in German also called ‘liquor cerebrospinalis’ or ‘Nervenwasser’ – with a particular protein called ‘beta-trace protein’, was the topic of my doctoral thesis ‘Isolation and chemical characterization of -trace pro­tein from human cerebro­spinal fluid: identification as pro­staglan­din D synthase’ (1992) in the CSF laboratory of the Neurological Clinic, MHH. CSF and the

    Body´s Own Stem Cells

    Isolation and Culture In the living organism, stem cells reside in niches to keep them in an optimal state. Here, the oxygen concentration is much lower than in ambient air with 21 % O2. Consequently, when the cells are taken from their natural environment and cultured in the lab, they experience a notable change in

    Conjoined Twins for Biohybrid Implants

    Photo: Dr. Sebastian Heene In November 2025, NIFE was open to the public (https://nife-hannover.de/erfolgreicher-tag-der-offenen-tuer/) demonstrating its manifold activities in research and translation. I (Prof. Dr. Andrea Hoffmann) contributed a talk on “Stem Cells and Immune Cells: Conjoined Twins for Novel Biohybrid Implants”. The term ´conjoined twins´ alludes to the inseparable functions of both cell types

    Two-weeks lab course “Introduction into cell culture technology of animal cells”, annually in September

    For students in life science (B.Sc.), Leibniz University. Statement of a student from the 2023 course: The practical course for the lecture “Adult stem cells in regenerative medicine” was a lot of fun. Prof. Hoffmann skilfully combines theory and practice with the help of Yvonne, Kirsten and Anika. Both the experiments and the associated theory

    Cardiac Allograft Vasculopathy

    Gene Polymorphisms as Risk Factors In transplanted hearts (also called ̒cardiac allograftsʼ) blood vessels may clog after transplantation. This is called vasculopathy and leads to rejection of the graft. Consequently, for long-time survival of transplanted hearts a strict control of the organ function is mandatory.Patients may have genetic predispositions for upcoming rejection. My work interrogated

    Tendon

    New data on gene expressions allow diagnosis It is often difficult to distinguish healthy from diseased tendons and to choose the right patient treatment. We aim to identify a pattern of gene markers that might allow such differentiation. To do so, we have isolated RNA from different tendons from more than 80 human patients and
