The first clinical trial in Tohoku university hospital after the Great East JAPAN Earthquake: The heroic efforts of my friend, professor Masashi Aoki

The Great East Japan Earthquake of 2011 seriously jeopardized our collaborative research with Professor Masashi Aoki (Tohoku University School of Medicine) on the development of new therapies for amyotrophic lateral sclerosis (ALS) using hepatocyte growth factor. After the earthquake struck, Professor Aoki made a tremendous contribution to saving patients' lives and to recovering from the disastrous situation. Thanks to his strong leadership and support from many reliable colleagues, we could finally start new clinical trials for ALS patients. In this article, I wish to introduce Professor Aoki's heroic efforts.
