Fotios Sampaziotis

Title: Fotios Sampaziotis: Innovator in Cholangiocyte Research

Introduction

Fotios Sampaziotis is a prominent inventor based in Hitchin, GB. He has made significant contributions to the field of cholangiocyte research, focusing on methods to expand and produce cholangiocyte progenitor cells. His innovative work has led to the development of two notable patents.

Latest Patents

Fotios Sampaziotis holds two patents that showcase his expertise in cholangiocyte research. The first patent, titled "Methods of expanding cholangiocytes," relates to the expansion of primary cholangiocytes in the form of cholangiocyte organoids (COs). This invention utilizes culture conditions that inhibit canonical Wnt signaling while potentiating non-canonical Wnt/PCP signaling. The patent provides methods, expanded populations of cholangiocytes, and medical applications of these expanded cells. The second patent, "In vitro production of cholangiocytes," focuses on the efficient generation of cholangiocyte progenitor (CP) cells. In this process, foregut stem cells (FSCs) are cultured in a hepatic induction medium to produce hepatoblasts, which are then cultured in a biliary induction medium to generate cholangiocyte progenitors (CPs). These CPs can be matured into cholangiocyte-like cells (CLCs) that exhibit the functional properties of common bile duct cholangiocytes.
