Sickle Cell Disease Spotlight: Dr. Yutaka Niihara and Grateful Patient Juanita Gougis

Sickle cell disease; Regenerative medicine

Research Description

Dr. Niihara has been involved in patient care and research for sickle cell disease for most of his career, is the founder of Emmaus Life Sciences, Inc., and the principal inventor of Endari, an L-glutamine therapy for treatment of sickle cell disease approved by FDA in July 2017. Additionally, his laboratory focuses on regenerative medicine using cell sheet technology. This treatment uses autologous progenitor cell sheets to repair damaged organs such as cornea epithelium and myocardium.
