Prof‭. ‬Michel Revel‭, ‬MD‭, ‬PhD‭ ‬ | Chief Scientist

Prof‭. ‬Revel is Professor Emeritus of Molecular Genetics at the Weizmann Institute of Science‭. ‬His research on Interferon‭, ‬its mechanisms of action and the isolation of the human Interferon-beta gene‭, ‬have led to the development of Interferon-beta therapy for the treatment of multiple sclerosis‭, ‬Rebif®‭, ‬Blockbuster drug marketed worldwide‭.‬


In recent years‭, ‬Prof‭. ‬Revel's laboratory focused on hESC and succeeded to produce nerve myelinating cells that‭, ‬when transplanted in myelin-deficient animals‭, ‬have regenerated the myelin coating‭. ‬These studies contributed to the development of a suspension culture technology for hESC which can then be used to produce differentiated human cells such as insulin-producing pancreatic‭ ‬beta cells and nerve myelinating cells‭.‬


Alongside his research and development activity‭, ‬Prof‭. ‬Revel is deeply involved in the ethics of science and biotechnology‭, ‬and‭ ‬served as chairman of the Israel National Bioethics Council‭, ‬and was a member of the International Bioethics Committee of UNESCO‭.‬


Prof‭. ‬Revel was the recipient of the Israel Prize for medical research‭, ‬the EMET Prize for biotechnology‭, ‬and is a member of the‭ ‬Israel Academy of Science and Humanities‭. ‬He has been a member of Israel's National Committee for Biotechnology‭, ‬serving for three years as its chairman‭.‬

Ariel Revel, MD, | Director of Medical Affairs

Prof. Ariel Revel, MD, is a professor of medicine at Tel Aviv University and a Visiting Professor at Oxford University in the UK and Stanford University in California. He is among Israel's leading specialists in gynecology and obstetrics and has for many years been involved in IVF and minimally invasive surgery. 

Ariel Revel served as a battalion and brigade physician, and raised his family in Nataf. He volunteers with Etgarim, where he kayaks and rides tandem bikes with children and teens with disabilities, and with Physicians for Human Rights, as a physician at the clinic for status-less individuals in Jaffa.

He is a an important figure on the medical landscape, and this together with his impressive knowledge and many years of experience has produced one of the most fascinating books published in recent years in Israel.

Ariel at Kadimastem is responsible for the following areas

1) To represent the surgical and medical aspects of islet transplantation for patients with diabetes.

2) To promote to medical doctors that cell therapy is the future of medicine. To improve and perhaps cure neurodegenerative diseases such as ALS.

3) Present to general public and potential inventors the potential of human embryonic stem cells to produce clinical level adult cells to cure Diabetes, Glaucoma  and Traumatic Spinal Cord Injuries.

Kfir Molakandov PhD  | Director of Diabetes and Innovation

Dr. Kfir Molakandov started his academic career in developmental biology with Prof. Sarah Ferber's research on transdifferentiation of liver to the pancreas.


During his PhD, he trained at the Gene Therapy Center, Alabama, USA, and specialized in adenoviral vectors construction, modifications and purification. Following the completion of his thesis, Dr. Molakandov joined Kadimastem.


He leads the team that is developing cell-therapy for diabetes using Pluripotent Stem Cells as the cell source. His team has dedicated the last few years in developing a large scale robust protocol for generating islet cells in high quantities and high quality.


Currently, we have finalized the production process that includes a full characterization of the different stages of differentiation using molecular tools and physiological parameters.


Accordingly, we are now moving towards the clinical application of this technology, aiming to bring these therapeutic cells to clinical trials.
