AAU, along with 91 other higher education organizations and institutions, yesterday sent a letter to Health and Human Services Secretary Alex Azar to express collective concern over the department’s policy imposing substantial barriers to and limiting the use of research using fetal tissue cells. In the letter, the group states that the policy “would impose substantial barriers to and limit the use of an essential biomedical research resource that has led to many advances in human health and remains critical for the development of new treatments for a wide range of serious diseases.”
