Scientists of the Max Delbruck Center for Molecular Medicine (MDC) Berlin-Buch and the Experimental and Clinical Research Center (ECRC) of MDC and Charité in Berlin-Buch have gained new insights into the development of epithelial cells and their molecular repertoire. Dr. Max Werth, Katharina Walentin and Professor Kai Schmidt-Ott have identified a transcription factor (grainyhead-like 2, Grhl2), which regulates the composition of the molecular "bridges" that link adjacent epithelial cells...
