Islet Laboratory Lab Manager
- Senior Postdoctoral Scientist
I am responsible for running the Clinical islet isolation facility. This is a purpose built, clean-room laboratory, licenced by the Human Tissue Authority for the aseptic production of pancreatic islet cells from cadaveric donor pancreases. The islets are used for transplantation in patients with Type 1 diabetes who have unstable diabetes with severe complications.
The facility operates to pharmaceutical grade GMP standards. I have to ensure that the facility meets all operational and environmental targets of cleanliness & sterility and that all the preparations used for transplant in turn meet strict production criteria.
When islets cannot be transplanted and where there is research consent, I coordinate their distribution for research purposes. They are used by several groups in Oxford and a network of laboratories across the UK.
My research centres on improving islet isolation, understanding the nature of the extracellular matrix at the islet-exocrine interface and its digestion by collagenase enzyme-blends. The goal is to be able to tailor the composition of the collagenase blend to different donor types and so optimise the yield of islets from all donors.
