Regenerative medicine

Overview

Tim Woodfield thumbProfessor Tim Woodfield.

Tissue Engineering (TE) and Regenerative Medicine (RM) combine a patient’s own cells with biodegradable scaffolds and growth factors. These therapies may offer considerable advantages over current surgical interventions used to repair or regenerate damaged tissues following trauma or disease.

The CReaTE group (Christchurch Regenerative Medicine and Tissue Engineering Group), consists of a multidisciplinary research team led by Professor Tim Woodfield, and is working at the interface of cell-biology, biomaterials science and engineering.

Using advanced 3D scaffolds and in-vitro culture techniques, combined with adult human stem cells, our group is attempting to identify the complex cellular environments controlling tissue growth in 3D. We are also researching their application in translating cell-based therapies to the clinic.

Printing cartilage

Tim Woodfield thumbnailA third of the New Zealand population will be aged over 60 by 2051. This growth, combined with an elderly population living longer and more active lives, means an epidemic of degenerative joint disease is fast approaching. Dr Tim Woodfield, of the Christchurch Regenerative Medicine and Tissue Engineering (CReaTE) Group, is working on a way to address this epidemic.
