Project Title

Dissecting the mechanisms of endocrine lineage formation in gut and pancreas

Project Description

Endocrine cells in the intestine and pancreas secrete various hormones to regulate energy uptake and blood glucose homeostasis. Impairment and dysfunction of these cells is linked to the emergence of obesity, cardiovascular disease and type 2 diabetes, which are leading causes of death worldwide. Understanding the driving factors of endocrinogenesis and identification of conserved pathways is an essential prerequisite for the development of novel therapeutic approaches targeting the regenerative capacity of tissue resident (stem) cells in gut and pancreas. Utilizing mouse models and the potential of CRISPR/Cas9 gene editing tools during in vitro differentiation of human induced pluripotent stem cells (hiPSCs) towards pancreatic and intestinal tissue, we study the role of mechanosignalling and polarity cues during endocrine induction.
