Denise Aparecida Berti, Ph.D.

Senior Research Staff Scientist

I received my Ph.D. in 2010 under the supervision of Dr. Emer S. Ferro at the University of São Paulo, Brazil, studying mechanisms of intracellular peptide signaling in a model of insulin resistance and obesity in rats. In 2010, I joined the lab of Dr. Deborah Schechtman as a postdoctoral fellow at the Biochemistry Department of the University of São Paulo. My research focus was signaling pathways mediated by protein kinase C (PKC), specifically trying to elucidate the regulation of self-renewal of embryonic stem cells (ESC) by this family of kinase. In 2013, I moved to Israel as a visiting scientist at the Weizmann Institute of Science to start a collaboration with Dr. Rony Seger. The primary goal of this collaboration was to deepen my knowledge and gain new insights into the nuclear translocation of MAP kinases and their role on pluripotency and self-renewal of ESC. Considering my knowledge and experience with ESC, I decided to take on the challenge to explore my skills in the field of regenerative medicine. Therefore, in 2016 I joined Kadimastem, an Israel-based biotech company that was founded by Dr. Michel Revel. In this new role, I had the opportunity to be a part of the R&D team on diabetes, which focused on hESC differentiation to insulin-producing cells for cell therapy. In 2020, I joined Dr. Maike Sander’s lab as a senior research staff scientist where I am leading studies on ESC-derived beta cells to understand the pathogenesis of diabetes.
