• Hidetaka Hara (MD, PhD) is Associate Professor of Surgery at the University of Alabama at Birmingham. Dr. Hara obtained his MD from Kawasaki Medical School, Okayama, Japan in 1995, and then completed a general surgery fellowship and PhD at Department of Surgery at Hiroshima University, Japan. During his surgical and research training, he became interested in organ transplantation, particularly in the field of xenotransplantation. He came to the United States in May 2004 to gain further experience in transplant immunology. As a Postdoctoral Associate in Dr. David K.C. Cooper’s laboratory at the Thomas E. Starzl Transplantation Institute (STI), University of Pittsburgh, Dr. Hara performs experimental surgeries in large animal models, including pig-to-non-human-primate heart, kidney, liver and islet transplants; and pig-to-pig spleen, kidney, heart and islet transplants. Dr. Hara also has extensive in vitro research experience, investigating the human-to-pig immune response. Dr. Hara rapidly proved to be a valuable member of the group. He made the decision to dedicate himself full-time to research on organ transplantation, particularly in the field of xenotransplantation. Dr. Hara has recently developed interest in pig corneal xenotransplantation. Dr. Hara has contributed to illuminating how genetic modifications in pigs can protect their organs from human immune responses. He has gained very considerable experience and has made major contributions to the field, and his work is now well-known internationally.
    In view of his productivity and growing reputation, Dr. Hara was steadily promoted through the rank of Research Instructor (in 2007) to his present position of Research Assistant Professor (in 2011) at STI. Since Dr. Cooper has relocated his laboratory to the University of Alabama at Birmingham (UAB) where they plan to take xenotransplantation into the clinic within the next few years, Dr. Hara joined Dr. Cooper at UAB as an Assistant Professor of Surgery (on November, 2016). Dr. Hara was promoted from Assistant Professor to Associate Professor (in 2017) at UAB.

    Research Overview

  • I am interested in transplant immunology, particularly in the field of xenotransplantation. I have contributed to illuminating how genetic modifications in pigs can protect their organs from human immune responses.

  • Teaching Overview

  • I have an established record of excellence in teaching and monitoring. I personally supervised the work of all the research fellows, university students, and technicians who have gained experience in the laboratory at the University of Pittsburgh during the past 13 years. I have proved an excellent mentor, training the postdoctoral fellows and technicians in basic and advanced techniques of immunology, enabling many young members of the laboratory to coauthor manuscripts published by the group (Transplantation. 2008;86:1452-1462, Transfusion. 2009;49:2418-2429. Immunology. 2011;134:386-397, Cornea. 2016;35:105-13). I have given seminars in several centers in the USA, Japan, and China. In addition, I have participated as an invited guest speaker at the International Xenotransplantation Association. Many of my trainees (in Dr. Cooper’s laboratory) have presented at national and international meetings, including being invited as guest speakers. Several of his group’s fellows have received the Young Investigator Award at scientific conferences.
    Teaching experience: All were postdoctoral research fellows or medical or undergraduate students unless otherwise indicated.

    In addition to training more than a dozen postdoctoral fellows in Pittsburgh, I have been invited to two centers in China to help establish similar laboratories. Furthermore, our group continues to collaborate with several departments and companies, both domestic (internal) and international. These collaborative groups include the following groups:
    (i) Edmonton, Canada (Dr. James Shapiro at University of Alberta, Edmonton, Canada) focusing on islet transplantation in the GSMS site in humans as a clinical trial, (ii) Winnipeg, MB, Canada (Dr. Rizwan Manji, University of Manitoba) focusing on pig derived bioprosthetic heart valves, (iii) Palermo, Italy (Dr. Bruno Gridelli, ISMETT) in investigating pig-to-baboon hepatocyte xenotransplantation using a clinically-applicable immunosuppressive regimen, (iv) Moscow, Russia (Dr. Nicoli Bovin) focusing on the role of N-glycolylneuraminic acid (Neu-Gc) as a relevant pig antigen in xenotransplantation, (v) Beijing, China (Tongren Hospital, Drs. Zhiqiang Pan and Xiaojuan Dong) focusing on corneal xenotransplantation in NHPs, (vi) Shenzhen, China (Shenzhen Second Hospital, Drs. Chai, Lisha, Wang, Zhou) focusing on kidney and neonatal islet xenotransplantations in NHPs, (vii) Tulane University and Revivicor, Inc. (Dr. David Ayares) focusing on pig lung scaffold implantation in monkeys, (viii) UPMC (Dr. Martin Wijkstrom) focusing on the comparison of serum anti-pig antibody levels, memory T cells and T cell proliferative response to pig stimulator cells between patients with high and low panel-reactive antibodies, (ix) University of Pittsburgh/McGowan Institute (Dr. Yadong Wang) using bioengineered material sheets for wound repair in a diabetic pig model. My involvement was helping carry out in vivo studies (as an advisor). In addition, Dr. Wang and I (as a Co-PI) have received a NIH grant (RO1) to help cover the expense of these studies.

    In all the above mentioned collaborations I have strongly involved in each as either an active participant or as a teaching/advisor.
