 The study reports the expression pattern of angiotensin I converting enzyme 2, ACE2, across over 150 different cell types in all major human tissues and organs, revealing that ACE2 is mainly expressed in enterocytes, renal tubules, gallbladder, cardiomyocytes, male reproductive cells, placental trophoblasts, ductal cells, eye, and vasculature, with limited expression in the respiratory system.
