Dr. Zoë HewittAs Quality Assurance Manager of the Centre for Stem Cell Biology, Stem Cell Derivation Facility I am responsible for ensuring the quality and safety of human embryonic stem cells (hESCs) derived as raw materials for secondary clinical manufacture.
I have six years of experience culturing hESCs, including a period of time developing differentiation protocols for hESCs to Hepatocytes, and 12 months experience of quality management. It is anticipated that following the production of a suitable grade hESC line as a raw material I will be able to use these expertise to assist the Research Scientists involved in the London Project to develop their differentiation procedures for RPE cells inline with Good Manufacturing Practices (GMP).
The development of a Quality Management System which has been independently audited and considered to be of a high standard
Invited to speak at conferences on issues relating to developing quality management systems and deriving clinical grade human embryonic stem cells
Member of a National Quality Forum, dedicated to defining Quality and Safety Criteria for hESC raw materials
Part of a working group involved in defining the regulatory framework of hESC raw materials within the UK
