Paul Andrews BSC (Hons) PhD FSB


Dr. Paul D. Andrews

Prior to establishing Stem Cell Solutions Ltd, I was Senior Scientist and Project Leader at Cellartis AB, at the time world-leader in ethically derived hES cell lines and their derivatives, with bases in Dundee, Scotland and Gothenburg, Sweden.  My team was part of a larger collaboration with Lund University in Sweden and the Hagerdorn Institute in Denmark.We had significant success in developing novel defined and xeno-free media formulations for the growth and subsequent differentiation of human embryonic stem cells into beta-cell progenitors with the long term aim for their use in the therapy of type-2 diabetes (funded by Novo Nordisk). Cellartis was acquired in 2011 by the French biotech company Cellectis.

Human stem cells

Human Feeder-free ES cells

Prior to being recruited to Cellartis, I was Senior Scientist and Team Leader in the Drug Discovery Unit (DDU), based in the internationally renowned College of Life Sciences at the University of Dundee in Scotland. In his position I led the Stem Cell Technologies team which performed a range of high content small molecule screens on human ES cells and their derivatives – a successful collaboration with Cellartis AB and 3 academic groups within Scotland, funded by ITI Life Sciences (now Scottish Enterprise). The programme was commercial in outlook and timeline/milestone driven. Building on my knowledge in the field of microscopy, I established high content screening (HCS) capabilities for the DDU and subsequently applied this to identify a portfolio of small molecules able to manipulate human ES cells fate. I acquired an in-depth understanding of the drug discovery process during this time. We were able to establish a robust platform for industry-standard screening stem cells from scratch.

Paul Andrews Nikon Small World

Two Telophase Cell Dividing (Nikon Small World Prize winner)

Prior to entering the drug discovery field, I achieved a track record in biochemistry, cell biology and high-end microscopy, mainly in oncology-related areas, in the laboratory of Jason Swedlow.

Prior to joining Jason’s lab I spent two years running a fledgling Microscope facility (centred around a DeltaVision Microscope) and therefore was exposed to a wide range of imaging techniques and cellular/organismal systems.

My focus ever since graduating from my PhD program was on understanding signalling pathways and their regulation of the cell cycle and the cytoskeleton. I have worked extensively on Aurora B protein kinase and PP1 protein phosphatase. I also have extensive experience of molecular and classical genetics using budding yeast gained over 7 years in the laboratory Michael Stark in at the University of Dundee. My PhD with David Hornby at the University of Sheffield, was concerned with the characterisation and regulation of  human DNA Methyltransferase.
