Aron Moscona

With sadness, the MBL announces the passing of Life Corporation Member Dr. Aron Moscona. Dr. Moscona died of heart failure on January 14 in Manhattan. The MBL flag will be lowered in his memory.

Dr. Moscona taught in the Embryology Course from 1960 to 1963. He became an MBL Corporation Member in 1962.

Dr. Moscona provided early insights into how cells in the developing embryo find one another and interact. His work led to the discovery of cadherins, the molecules on cell surfaces that recognize one another. The discovery paved the way for the exploration of processes by which blood cells leave the bone marrow to circulate, sperm and eggs free themselves, and skin cells cross gaps to close a wound.

Dr. Moscona and his wife, Malka, were on the faculty of the University of Chicago for decades and taught numerous developmental biologists.

Dr. Moscona grew up in Haifa, Israel and received his doctorate from Hebrew University. In addition to his ties to the MBL, he conducted research at Stangeways Research Laboratory in Cambridge, England.
