About Us

During the past 19 years, Dr. Amit has dedicated her research work in laying the methodological groundwork for appropriate pluripotent stem cells culture. She conducted her Ph.D. degree in the Department of Medical Sciences at the Faculty of Medicine, Technion. Her thesis dealt with the isolation of human embryonic stem cells and their directed differentiation into blood cells.

In 1998 she joined Prof. Thomson at the University of Wisconsin where she was trained in growing and isolating embryonic stem cell lines. Upon her return to Israel she derived the first human embryonic stem cell line in Israel, third worldwide. Her areas of expertise are in the derivation of primary cell lines (adults, embryonic and fetal), culture medium development, cells mass production using dynamic systems, stem cells directed differentiation, and good manufacturing procedures.

Dr. Amit has published articles describing novel culture methods for culturing pluripotent stem cells, culturing stem cells in carrier-free suspension, as well as studies on stem cells directed differentiation methods. Her research experience is recognized with over 45 published papers which all together were cited about 10,000 times, as speaker with 30 national and international invited lectures, 15 patent families, and as co-investigator on grants in the field of pluripotent stem cells research. Some of these patents were used as the base for establishing Accellta, a stem cells company, where she serves as the CEO/CTO and co-founder.

Dr. Amit also wrote a book summarizing major culture methods for human pluripotent stem cells. On the academic side, she had trained over 10 graduate students and resident medical student research projects. In recent years, Michal serves as a Senior Lecturer at the Ephraim Katzir Department of Biotechnology Braude College.
