Dr. Dorothee Bornhorst, Prof. Seyfried Lab Alumni, won the GfE Dissertation Award 2022


The German Society for Developmental Biology (GfE) announced that Dr. Dorothee Bornhorst has won the 2022 PhD dissertation award.


Dr. Bornhorst received the prize for her thesis entitled “Intra-organ communication within the developing zebrafish heart involves mechanical coupling of myocardium and endocardium”. The research was carried out in Prof. Salim Seyfried’s laboratory at Hannover Medical School and Potsdam University (Germany) and uncovered that biomechanical signaling pathways play an important role in cardiac growth coordination. Dr. Bornhorst’s work suggests that the growth of the endocardium, a specialized endothelial tissue lining the interior of the heart, results from myocardial chamber volume expansion and ends when the tension on the tissue is relaxed (published in Nature Communications, 2019).


This award has been established to recognize and encourage outstanding research achievements during the dissertation phase working in the field of developmental biology. During their society meeting in September at the University of Hohenheim, Stuttgart, this award was given in an honor ceremony.
